Spring to Java EE, Part Three - new tech article on otn/java

- by Janice J. Heiss

In a new article up on otn/java, Java EE expert David Heffelfinger continues his series exploring the relative strengths and weaknesses of Java EE and Spring. Here, he demonstrates how easy it is to develop the data layer of an application using Java EE, JPA, and the NetBeans IDE instead of the Spring Framework.In the first two parts of the series, he generated a complete Java EE application by using JavaServer Faces (JSF) 2.0, Enterprise JavaBeans (EJB) 3.1, and Java Persistence API (JPA) 2.0 from Spring’s Pet Clinic MySQL schema, thus showing how easy it is to develop an application whose functionality equaled that of the Spring sample application.In his new article, Heffelfinger tweaks the application to make it more user friendly.From the article:“The generated application displays primary keys on some of the pages, and these keys are surrogate primary keys—meaning that they have no business value and are used strictly as a unique identifier—so there is no reason why they should be visible to the user. In addition, we will modify some of the generated labels to make them more user-friendly.”He concludes the article with a summary:“The Java EE version of the application is not a straight port of the Spring version. For example, the Java EE version enables us to create, update, and delete veterinarians as well as veterinary specialties, whereas the Spring version of the application enables us only to view veterinarians and specialties. Additionally, the Spring version has a single page for managing/viewing owners, pets, and visits, whereas the Java EE version of the application has separate pages for each of these entities.The other thing we should keep in mind is that we didn’t actually write a lot of the code and markup for the Java EE version of the application, because the bulk of it was generated by the NetBeans wizard.” Have a look at the complete article here.

Grading an algorithm: Readability vs. Compactness

- by amiregelz

Consider the following question in a test \ interview: Implement the strcpy() function in C: void strcpy(char *destination, char *source); The strcpy function copies the C string pointed by source into the array pointed by destination, including the terminating null character. Assume that the size of the array pointed by destination is long enough to contain the same C string as source, and does not overlap in memory with source. Say you were the tester, how would you grade the following answers to this question? 1) void strcpy(char *destination, char *source) { while (*source != '\0') { *destination = *source; source++; destionation++; } *destionation = *source; } 2) void strcpy(char *destination, char *source) { while (*(destination++) = *(source++)) ; } The first implementation is straightforward - it is readable and programmer-friendly. The second implementation is shorter (one line of code) but less programmer-friendly; it's not so easy to understand the way this code is working, and if you're not familiar with the priorities in this code then it's a problem. I'm wondering if the first answer would show more complexity and more advanced thinking, in the tester's eyes, even though both algorithms behave the same, and although code readability is considered to be more important than code compactness. It seems to me that since making an algorithm this compact is more difficult to implement, it will show a higher level of thinking as an answer in a test. However, it is also possible that a tester would consider the first answer not good because it's not readable. I would also like to mention that this is not specific to this example, but general for code readability vs. compactness when implementing an algorithm, specifically in tests \ interviews.

Small-scale database options for .NET

- by raney

I have a .NET 4.0/WPF based application I've developed and maintain for my company that acts as a friendly GUI central-point-of-information, combining information pulled from a couple of SQL databases, as well as CSV exports from a few other applications. I would like to build out my own database to support the entirety of the information that the application accesses, so that I could have a service running on my server that would read in necessary remote SQL info and file exports, to provide the user's application with a single database to connect to, as well as to remove all of the file handling currently involved in the program (copying new CSV resources from network location, reading them into memory each launch.) I have complete control and flexibility here as long as the user's experience isn't affected, and this is as much a learning experience as it is tidying up. Caveat being, I don't have much in the way of a budget. Right now I recognize my options to be: SQL Express - I'm comfortable with the server setup, I like ADO.NET and LINQ to SQL. I feel that I have the least to learn here, but it would let me focus on SQL in a familiar environment. Perhaps in conjunction with Entity Framework? MongoDB - I don't know a whole lot about, but I've heard the name enough to make me curious. Brief research seems friendly enough, and there is .NET support. I like working with open source projects. My questions are: What's popular and extensible right now? I'm not far from starting to job-hunt, and I'd like this project to be relevant going forward. What am I missing? Pros, cons? Other options? What plays well with .NET? What are the things I should be considering, the questions I should be asking, when making a decision like this? Thanks for your time.

How to target just one search engine and optimise for that

- by mickburkejnr

I've been dabbling with SEO a lot in the last 6 months, and one thing that has surprised me is the disparity between Google and Bing in the way they deliver results. A website ranked for a specific keyword/phrase on Google may rank 3rd on the first page, but using the same keyword/phrase on Bing will display the same website but ranked 15th for the exact same keyword/phrase. I came up with the idea to increase traffic to my website by targetting Bing instead of Google for several reasons. The biggest one is that while it's not the biggest search provider, people still use it, and I feel that if other websites have been "neglected" and not optimised for Bing my website would stand a better chance of getting near the top of their search rankings. The question is though how would I do this? A lot of the SEO advice on the internet is generic, but I can't help feeling it's Google orientated for obvious reasons. How could I optimise my website to be Bing friendly, rather than Google friendly? I know it sounds like suicide as I'm taking myself out of the Google mindset, but I feel it could work wonders for traffic to the site.

How to make it so units don't stack up in one location?

- by Daggio

So I'm making a game in AS3, it's a strategy DotA-like game (for flash game equivalent, there's UDE) so far so good, I have the A* pathfinding algorithm all sorted out and the minion units move to the desired location as I want them to be. The problem a rise when a unit stops in a node that has already occupied by another friendly unit. Both (or more than two) of them stacks up in one location, it looks like they're one unit. I want to add collision detection so when they collide they don't stack up together. But now they stop when they collide on they way to a node. This isn't good because they won't move at all midway (they won't respond to enemy attacks like that). I've added a deltatime so they only stopped for 2 seconds before they move again to their designated designation. This moves them again but they flicker. Not how I want it. So, like the title said. How to make more than one units don't stack up in a node? And if possible, how to make them not flicker while moving (it's good if they can tell other friendly units on the way and avoid them accordingly)?

Want Google to index redirect urls

- by Dave Goten

I'm having issues with users who think that Google Search is the address bar. Some of the sites that link to my site use user friendly addresses with 301 redirects to pages that have less friendly URLs. So, for example if I enter www.foo.com/bar it goes to www.bar.com/page.php?some-parameters-and-utm-codes-etc usually this is done by a 301 redirect in order to keep the SEO from foo.com on bar.com and so on, which I believe is standard practice. However, lately there have been more and more people searching www.foo.com/bar instead of going to www.foo.com/bar directly and because the page /bar is nothing more than a redirect it has no SEO that I know of. Things I've thought of but haven't been able to test, because Google takes forever to update :) (and I'm lazy like that), include using Google sitemaps and having them enter their redirects as entries there. (I could see this working if they were the top search entry all the time, and it might appear as a sitelink, but I don't know if that'll make the url itself show up in searches) Using Canonical tags on my pages to the redirects they set up. Which is a nightmare in itself because of the nature of my pages. One week the www.foo.com/bar might go to www.bar.com/pageA.php the next it might goto www.bar.com/pageB.php and having to remember to take the canonical tag off of pageA, so that it doesn't get confused with pageB would be a pain. Using 302 redirects -.- So I guess the question here is, does anyone have any experience or knowledge about this? What should I do to make www.foo.com/bar show up when someone 'searches' for this redirect url?

Dual-Boot Problem

- by user171379

I have a HP laptop that originally had Windows 7 OS on it, I partioned the drive and allocated 100gb (est.) for the ubuntu install. the install went fine i have ubuntu and windows 7 still on the computer. But I can not get the OS boot screen to show ubuntu as an OS. I can while start up pull up the start menu screen via ESC. Key and press F9 for Boot Device Options and get the boot manager screen and it lists... OS boot manager, Ubuntu (Hitachi HTS 543232A7A384), boot from EFI file, and Notebook Hard Drive... I can boot Ubuntu from this screen by selecting Ubuntu. But i would like to make it easier to access. The computer boot is not for myself otherwise it would not be a problem i would remove windows altogether. I would like to make it basically "User Friendly" if that's at all possible and make the OS boot screen show Ubuntu as a bootable OS as well as Windows 7. on the boot selection screen. Any help on this issue would be greatly appreciated, I've looked to see if i could find the answer and maybe i've overlooked something so here I am. Like i said i need it to be as user friendly as possible and force the user to choose windows 7 or ubuntu not send them into one or the other without them being allowed to choose. I can get any information you might need if necessary but i dont know exactly what you'll need other than what i've given. Ubuntu version is the 13.04 just so you know.

WCF REST Error Handler

- by Elton Stoneman

I’ve put up on GitHub a sample WCF error handler for REST services, which returns proper HTTP status codes in response to service errors. The code is very simple – a ServiceBehavior implementation which can be specified in config to tag the RestErrorHandler to a service. Any uncaught exceptions will be routed to the error handler, which sets the HTTP status code and description in the response, based on the type of exception. The sample defines a ClientException which can be thrown in code to indicate a problem with the client’s request, and the response will be a status 400 with a friendly error message: throw new ClientException("Invalid userId. Must be provided as a positive integer"); - responds: Request URL http://localhost/Sixeyed.WcfRestErrorHandler.Sample/ErrorProneService.svc/lastLogin?userId=xyz Error Status Code: 400, Description: Invalid userId. Must be provided as a positive integer Any other uncaught exceptions are hidden from the client. The full details are logged with a GUID to identify the error, and the response to the client is a status 500 with a generic message giving them the GUID to follow up on: var iUserId = 0; var dbz = 1 / iUserId; - logs the divide-by-zero error and responds: Request URL http://localhost/Sixeyed.WcfRestErrorHandler.Sample/ErrorProneService.svc/dbz Error Status Code: 500, Description: Something has gone wrong. Please contact our support team with helpdesk ID: C9C5A968-4AEA-48C7-B90A-DEC986F80DA5 The sample demonstrates two techniques for building the response. For client exceptions, a friendly HTML response is sent in the body as well as the status code and description. Personally I prefer not to do that – it doesn’t make sense to get a 400 error and find text/html when you’re expecting application/json, but it’s easy to do if that’s the functionality you want. The other option is to send an empty response, which the sample does with server exceptions. The obvious extension is to have multiple exceptions representing all the status codes you want to provide, then your code is as simple as throwing the relevant exception – UnauthorizedException, ForbiddenExeption, NotImplementedException etc – anywhere in the stack, and it will be handled nicely.

- by Mona

I want to get data from MySQL database using PHP and display it in Android activity. I code it and pass JSON Array but there is a problem i dont know how to connect to server and my all database is on local server. I code it Kindly tell me where i go wrong so I can get exact results. I'll be very thankful to you. My PHP code is: <?php $response = array(); require_once __DIR__ . '/db_connect.php'; $db = new DB_CONNECT(); if (isset($_GET["cid"])) { $cid = $_GET['cid']; // get a product from products table $result = mysql_query("SELECT *FROM my_task WHERE cid = $cid"); if (!empty($result)) { // check for empty result if (mysql_num_rows($result) > 0) { $result = mysql_fetch_array($result); $task = array(); $task["cid"] = $result["cid"]; $task["cus_name"] = $result["cus_name"]; $task["contact_number"] = $result["contact_number"]; $task["ticket_no"] = $result["ticket_no"]; $task["task_detail"] = $result["task_detail"]; // success $response["success"] = 1; // user node $response["task"] = array(); array_push($response["my_task"], $task); // echoing JSON response echo json_encode($response); } else { // no task found $response["success"] = 0; $response["message"] = "No product found"; // echo no users JSON echo json_encode($response); } } else { // no task found $response["success"] = 0; $response["message"] = "No product found"; echo json_encode($response); } } else { $response["success"] = 0; $response["message"] = "Required field(s) is missing"; // echoing JSON response echo json_encode($response);} ?> My Android code is: public class My_Task extends Activity { TextView cus_name_txt, contact_no_txt, ticket_no_txt, task_detail_txt; EditText attend_by_txtbx, cus_name_txtbx, contact_no_txtbx, ticket_no_txtbx, task_detail_txtbx; Button btnSave; Button btnDelete; String cid; // Progress Dialog private ProgressDialog tDialog; // Creating JSON Parser object JSONParser jParser = new JSONParser(); ArrayList<HashMap<String, String>> my_taskList; // single task url private static final String url_read_mytask = "http://198.168.0.29/mobile/read_My_Task.php"; // url to update product private static final String url_update_mytask = "http://198.168.0.29/mobile/update_mytask.php"; // url to delete product private static final String url_delete_mytask = "http://198.168.0.29/mobile/delete_mytask.php"; // JSON Node names private static String TAG_SUCCESS = "success"; private static String TAG_MYTASK = "my_task"; private static String TAG_CID = "cid"; private static String TAG_NAME = "cus_name"; private static String TAG_CONTACT = "contact_number"; private static String TAG_TICKET = "ticket_no"; private static String TAG_TASKDETAIL = "task_detail"; private static String attend_by_txt; // task JSONArray JSONArray my_task = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.my_task); cus_name_txt = (TextView) findViewById(R.id.cus_name_txt); contact_no_txt = (TextView)findViewById(R.id.contact_no_txt); ticket_no_txt = (TextView)findViewById(R.id.ticket_no_txt); task_detail_txt = (TextView)findViewById(R.id.task_detail_txt); attend_by_txtbx = (EditText)findViewById(R.id.attend_by_txt); attend_by_txtbx.setText(My_Task.attend_by_txt); Spinner severity = (Spinner) findViewById(R.id.severity_spinner); // Create an ArrayAdapter using the string array and a default spinner layout ArrayAdapter<CharSequence> adapter3 = ArrayAdapter.createFromResource(this, R.array.Severity_array, android.R.layout.simple_dropdown_item_1line); // Specify the layout to use when the list of choices appears adapter3.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // Apply the adapter to the spinner severity.setAdapter(adapter3); // save button btnSave = (Button) findViewById(R.id.btnSave); btnDelete = (Button) findViewById(R.id.btnDelete); // getting product details from intent Intent i = getIntent(); // getting product id (pid) from intent cid = i.getStringExtra(TAG_CID); // Getting complete product details in background thread new GetProductDetails().execute(); // save button click event btnSave.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { // starting background task to update product new SaveProductDetails().execute(); } }); // Delete button click event btnDelete.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { // deleting product in background thread new DeleteProduct().execute(); } }); } /** * Background Async Task to Get complete product details * */ class GetProductDetails extends AsyncTask<String, String, String> { /** * Before starting background thread Show Progress Dialog * */ @Override protected void onPreExecute() { super.onPreExecute(); tDialog = new ProgressDialog(My_Task.this); tDialog.setMessage("Loading task details.

jQuery, ASP.NET, and Browser History

- by Stephen Walther

One objection that people always raise against Ajax applications concerns browser history. Because an Ajax application updates its content by performing sneaky Ajax postbacks, the browser backwards and forwards buttons don’t work as you would normally expect. In a normal, non-Ajax application, when you click the browser back button, you return to a previous state of the application. For example, if you are paging through a set of movie records, you might return to the previous page of records. In an Ajax application, on the other hand, the browser backwards and forwards buttons do not work as you would expect. If you navigate to the second page in a list of records and click the backwards button, you won’t return to the previous page. Most likely, you will end up navigating away from the application entirely (which is very unexpected and irritating). Bookmarking presents a similar problem. You cannot bookmark a particular page of records in an Ajax application because the address bar does not reflect the state of the application. The Ajax Solution There is a solution to both of these problems. To solve both of these problems, you must take matters into your own hands and take responsibility for saving and restoring your application state yourself. Furthermore, you must ensure that the address bar gets updated to reflect the state of your application. In this blog entry, I demonstrate how you can take advantage of a jQuery library named bbq that enables you to control browser history (and make your Ajax application bookmarkable) in a cross-browser compatible way. The JavaScript Libraries In this blog entry, I take advantage of the following four JavaScript files: jQuery-1.4.2.js – The jQuery library. Available from the Microsoft Ajax CDN at http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js jquery.pager.js – Used to generate pager for navigating records. Available from http://plugins.jquery.com/project/Pager microtemplates.js – John Resig’s micro-templating library. Available from http://ejohn.org/blog/javascript-micro-templating/ jquery.ba-bbq.js – The Back Button and Query (BBQ) Library. Available from http://benalman.com/projects/jquery-bbq-plugin/ All of these libraries, with the exception of the Micro-templating library, are available under the MIT open-source license. The Ajax Application Let’s start by building a simple Ajax application that enables you to page through a set of movie database records, 3 records at a time. We’ll use my favorite database named MoviesDB. This database contains a Movies table that looks like this: We’ll create a data model for this database by taking advantage of the ADO.NET Entity Framework. The data model looks like this: Finally, we’ll expose the data to the universe with the help of a WCF Data Service named MovieService.svc. The code for the data service is contained in Listing 1. Listing 1 – MovieService.svc using System.Data.Services; using System.Data.Services.Common; namespace WebApplication1 { public class MovieService : DataService<MoviesDBEntities> { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("Movies", EntitySetRights.AllRead); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } } The WCF Data Service in Listing 1 exposes the movies so that you can query the movie database table with URLs that looks like this: http://localhost:2474/MovieService.svc/Movies -- Returns all movies http://localhost:2474/MovieService.svc/Movies?$top=5 – Returns 5 movies The HTML page in Listing 2 enables you to page through the set of movies retrieved from the WCF Data Service. Listing 2 – Original.html <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Movies with History</title> <link href="Design/Pager.css" rel="stylesheet" type="text/css" /> </head> <body> <h1>Page <span id="pageNumber"></span> of <span id="pageCount"></span></h1> <div id="pager"></div> <br style="clear:both" /><br /> <div id="moviesContainer"></div> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="App_Scripts/Microtemplates.js" type="text/javascript"></script> <script src="App_Scripts/jquery.pager.js" type="text/javascript"></script> <script type="text/javascript"> var pageSize = 3, pageIndex = 0; // Show initial page of movies showMovies(); function showMovies() { // Build OData query var query = "/MovieService.svc" // base URL + "/Movies" // top-level resource + "?$skip=" + pageIndex * pageSize // skip records + "&$top=" + pageSize // take records + " &$inlinecount=allpages"; // include total count of movies // Make call to WCF Data Service $.ajax({ dataType: "json", url: query, success: showMoviesComplete }); } function showMoviesComplete(result) { // unwrap results var movies = result["d"]["results"]; var movieCount = result["d"]["__count"] // Show movies using template var showMovie = tmpl("<li><%=Id%> - <%=Title %></li>"); var html = ""; for (var i = 0; i < movies.length; i++) { html += showMovie(movies[i]); } $("#moviesContainer").html(html); // show pager $("#pager").pager({ pagenumber: (pageIndex + 1), pagecount: Math.ceil(movieCount / pageSize), buttonClickCallback: selectPage }); // Update page number and page count $("#pageNumber").text(pageIndex + 1); $("#pageCount").text(movieCount); } function selectPage(pageNumber) { pageIndex = pageNumber - 1; showMovies(); } </script> </body> </html> The page in Listing 3 has the following three functions: showMovies() – Performs an Ajax call against the WCF Data Service to retrieve a page of movies. showMoviesComplete() – When the Ajax call completes successfully, this function displays the movies by using a template. This function also renders the pager user interface. selectPage() – When you select a particular page by clicking on a page number in the pager UI, this function updates the current page index and calls the showMovies() function. Figure 1 illustrates what the page looks like when it is opened in a browser. Figure 1 If you click the page numbers then the browser history is not updated. Clicking the browser forward and backwards buttons won’t move you back and forth in browser history. Furthermore, the address displayed in the address bar does not change when you navigate to different pages. You cannot bookmark any page except for the first page. Adding Browser History The Back Button and Query (bbq) library enables you to add support for browser history and bookmarking to a jQuery application. The bbq library supports two important methods: jQuery.bbq.pushState(object) – Adds state to browser history. jQuery.bbq.getState(key) – Gets state from browser history. The bbq library also supports one important event: hashchange – This event is raised when the part of an address after the hash # is changed. The page in Listing 3 demonstrates how to use the bbq library to add support for browser navigation and bookmarking to an Ajax page. Listing 3 – Default.html <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Movies with History</title> <link href="Design/Pager.css" rel="stylesheet" type="text/css" /> </head> <body> <h1>Page <span id="pageNumber"></span> of <span id="pageCount"></span></h1> <div id="pager"></div> <br style="clear:both" /><br /> <div id="moviesContainer"></div> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="App_Scripts/jquery.ba-bbq.js" type="text/javascript"></script> <script src="App_Scripts/Microtemplates.js" type="text/javascript"></script> <script src="App_Scripts/jquery.pager.js" type="text/javascript"></script> <script type="text/javascript"> var pageSize = 3, pageIndex = 0; $(window).bind('hashchange', function (e) { pageIndex = e.getState("pageIndex") || 0; pageIndex = parseInt(pageIndex); showMovies(); }); $(window).trigger('hashchange'); function showMovies() { // Build OData query var query = "/MovieService.svc" // base URL + "/Movies" // top-level resource + "?$skip=" + pageIndex * pageSize // skip records + "&$top=" + pageSize // take records +" &$inlinecount=allpages"; // include total count of movies // Make call to WCF Data Service $.ajax({ dataType: "json", url: query, success: showMoviesComplete }); } function showMoviesComplete(result) { // unwrap results var movies = result["d"]["results"]; var movieCount = result["d"]["__count"] // Show movies using template var showMovie = tmpl("<li><%=Id%> - <%=Title %></li>"); var html = ""; for (var i = 0; i < movies.length; i++) { html += showMovie(movies[i]); } $("#moviesContainer").html(html); // show pager $("#pager").pager({ pagenumber: (pageIndex + 1), pagecount: Math.ceil(movieCount / pageSize), buttonClickCallback: selectPage }); // Update page number and page count $("#pageNumber").text(pageIndex + 1); $("#pageCount").text(movieCount); } function selectPage(pageNumber) { pageIndex = pageNumber - 1; $.bbq.pushState({ pageIndex: pageIndex }); } </script> </body> </html> Notice the first chunk of JavaScript code in Listing 3: $(window).bind('hashchange', function (e) { pageIndex = e.getState("pageIndex") || 0; pageIndex = parseInt(pageIndex); showMovies(); }); $(window).trigger('hashchange'); When the hashchange event occurs, the current pageIndex is retrieved by calling the e.getState() method. The value is returned as a string and the value is cast to an integer by calling the JavaScript parseInt() function. Next, the showMovies() method is called to display the page of movies. The $(window).trigger() method is called to raise the hashchange event so that the initial page of records will be displayed. When you click a page number, the selectPage() method is invoked. This method adds the current page index to the address by calling the following method: $.bbq.pushState({ pageIndex: pageIndex }); For example, if you click on page number 2 then page index 1 is saved to the URL. The URL looks like this: Notice that when you click on page 2 then the browser address is updated to look like: /Default.htm#pageIndex=1 If you click on page 3 then the browser address is updated to look like: /Default.htm#pageIndex=2 Because the browser address is updated when you navigate to a new page number, the browser backwards and forwards button will work to navigate you backwards and forwards through the page numbers. When you click page 2, and click the backwards button, you will navigate back to page 1. Furthermore, you can bookmark a particular page of records. For example, if you bookmark the URL /Default.htm#pageIndex=1 then you will get the second page of records whenever you open the bookmark. Summary You should not avoid building Ajax applications because of worries concerning browser history or bookmarks. By taking advantage of a JavaScript library such as the bbq library, you can make your Ajax applications behave in exactly the same way as a normal web application.

Internet Explorer and Cookie Domains

- by Rick Strahl

I've been bitten by some nasty issues today in regards to using a domain cookie as part of my FormsAuthentication operations. In the app I'm currently working on we need to have single sign-on that spans multiple sub-domains (www.domain.com, store.domain.com, mail.domain.com etc.). That's what a domain cookie is meant for - when you set the cookie with a Domain value of the base domain the cookie stays valid for all sub-domains. I've been testing the app for quite a while and everything is working great. Finally I get around to checking the app with Internet Explorer and I start discovering some problems - specifically on my local machine using localhost. It appears that Internet Explorer (all versions) doesn't allow you to specify a domain of localhost, a local IP address or machine name. When you do, Internet Explorer simply ignores the cookie. In my last post I talked about some generic code I created to basically parse out the base domain from the current URL so a domain cookie would automatically used using this code:private void IssueAuthTicket(UserState userState, bool rememberMe) { FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, userState.UserId, DateTime.Now, DateTime.Now.AddDays(10), rememberMe, userState.ToString()); string ticketString = FormsAuthentication.Encrypt(ticket); HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, ticketString); cookie.HttpOnly = true; if (rememberMe) cookie.Expires = DateTime.Now.AddDays(10); var domain = Request.Url.GetBaseDomain(); if (domain != Request.Url.DnsSafeHost) cookie.Domain = domain; HttpContext.Response.Cookies.Add(cookie); } This code works fine on all browsers but Internet Explorer both locally and on full domains. And it also works fine for Internet Explorer with actual 'real' domains. However, this code fails silently for IE when the domain is localhost or any other local address. In that case Internet Explorer simply refuses to accept the cookie and fails to log in. Argh! The end result is that the solution above trying to automatically parse the base domain won't work as local addresses end up failing. Configuration Setting Given this screwed up state of affairs, the best solution to handle this is a configuration setting. Forms Authentication actually has a domain key that can be set for FormsAuthentication so that's natural choice for the storing the domain name: <authentication mode="Forms"> <forms loginUrl="~/Account/Login" name="gnc" domain="mydomain.com" slidingExpiration="true" timeout="30" xdt:Transform="Replace"/> </authentication> Although I'm not actually letting FormsAuth set my cookie directly I can still access the domain name from the static FormsAuthentication.CookieDomain property, by changing the domain assignment code to:if (!string.IsNullOrEmpty(FormsAuthentication.CookieDomain)) cookie.Domain = FormsAuthentication.CookieDomain; The key is to only set the domain when actually running on a full authority, and leaving the domain key blank on the local machine to avoid the local address debacle. Note if you want to see this fail with IE, set the domain to domain="localhost" and watch in Fiddler what happens. Logging Out When specifying a domain key for a login it's also vitally important that that same domain key is used when logging out. Forms Authentication will do this automatically for you when the domain is set and you use FormsAuthentication.SignOut(). If you use an explicit Cookie to manage your logins or other persistant value, make sure that when you log out you also specify the domain. IOW, the expiring cookie you set for a 'logout' should match the same settings - name, path, domain - as the cookie you used to set the value.HttpCookie cookie = new HttpCookie("gne", ""); cookie.Expires = DateTime.Now.AddDays(-5); // make sure we use the same logic to release cookie var domain = Request.Url.GetBaseDomain(); if (domain != Request.Url.DnsSafeHost) cookie.Domain = domain; HttpContext.Response.Cookies.Add(cookie); I managed to get my code to do what I needed it to, but man I'm getting so sick and tired of fixing IE only bugs. I spent most of the day today fixing a number of small IE layout bugs along with this issue which took a bit of time to trace down.© Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

Anti-Forgery Request in ASP.NET MVC and AJAX

- by Dixin

Background To secure websites from cross-site request forgery (CSRF, or XSRF) attack, ASP.NET MVC provides an excellent mechanism: The server prints tokens to cookie and inside the form; When the form is submitted to server, token in cookie and token inside the form are sent by the HTTP request; Server validates the tokens. To print tokens to browser, just invoke HtmlHelper.AntiForgeryToken():<% using (Html.BeginForm()) { %> <%: this.Html.AntiForgeryToken(Constants.AntiForgeryTokenSalt)%> <%-- Other fields. --%> <input type="submit" value="Submit" /> <% } %> which writes to token to the form:<form action="..." method="post"> <input name="__RequestVerificationToken" type="hidden" value="J56khgCvbE3bVcsCSZkNVuH9Cclm9SSIT/ywruFsXEgmV8CL2eW5C/gGsQUf/YuP" />  <input type="submit" value="Submit" /> </form> and the cookie: __RequestVerificationToken_Lw__=J56khgCvbE3bVcsCSZkNVuH9Cclm9SSIT/ywruFsXEgmV8CL2eW5C/gGsQUf/YuP When the above form is submitted, they are both sent to server. [ValidateAntiForgeryToken] attribute is used to specify the controllers or actions to validate them:[HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult Action(/* ... */) { // ... } This is very productive for form scenarios. But recently, when resolving security vulnerabilities for Web products, I encountered 2 problems: It is expected to add [ValidateAntiForgeryToken] to each controller, but actually I have to add it for each POST actions, which is a little crazy; After anti-forgery validation is turned on for server side, AJAX POST requests will consistently fail. Specify validation on controller (not on each action) Problem For the first problem, usually a controller contains actions for both HTTP GET and HTTP POST requests, and usually validations are expected for HTTP POST requests. So, if the [ValidateAntiForgeryToken] is declared on the controller, the HTTP GET requests become always invalid:[ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public class SomeController : Controller { [HttpGet] public ActionResult Index() // Index page cannot work at all. { // ... } [HttpPost] public ActionResult PostAction1(/* ... */) { // ... } [HttpPost] public ActionResult PostAction2(/* ... */) { // ... } // ... } If user sends a HTTP GET request from a link: http://Site/Some/Index, validation definitely fails, because no token is provided. So the result is, [ValidateAntiForgeryToken] attribute must be distributed to each HTTP POST action in the application:public class SomeController : Controller { [HttpGet] public ActionResult Index() // Works. { // ... } [HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult PostAction1(/* ... */) { // ... } [HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult PostAction2(/* ... */) { // ... } // ... } Solution To avoid a large number of [ValidateAntiForgeryToken] attributes (one attribute for one HTTP POST action), I created a wrapper class of ValidateAntiForgeryTokenAttribute, where HTTP verbs can be specified:[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)] public class ValidateAntiForgeryTokenWrapperAttribute : FilterAttribute, IAuthorizationFilter { private readonly ValidateAntiForgeryTokenAttribute _validator; private readonly AcceptVerbsAttribute _verbs; public ValidateAntiForgeryTokenWrapperAttribute(HttpVerbs verbs) : this(verbs, null) { } public ValidateAntiForgeryTokenWrapperAttribute(HttpVerbs verbs, string salt) { this._verbs = new AcceptVerbsAttribute(verbs); this._validator = new ValidateAntiForgeryTokenAttribute() { Salt = salt }; } public void OnAuthorization(AuthorizationContext filterContext) { string httpMethodOverride = filterContext.HttpContext.Request.GetHttpMethodOverride(); if (this._verbs.Verbs.Contains(httpMethodOverride, StringComparer.OrdinalIgnoreCase)) { this._validator.OnAuthorization(filterContext); } } } When this attribute is declared on controller, only HTTP requests with the specified verbs are validated:[ValidateAntiForgeryTokenWrapper(HttpVerbs.Post, Constants.AntiForgeryTokenSalt)] public class SomeController : Controller { // Actions for HTTP GET requests are not affected. // Only HTTP POST requests are validated. } Now one single attribute on controller turns on validation for all HTTP POST actions. Submit token via AJAX Problem For AJAX scenarios, when request is sent by JavaScript instead of form:$.post(url, { productName: "Tofu", categoryId: 1 // Token is not posted. }, callback); This kind of AJAX POST requests will always be invalid, because server side code cannot see the token in the posted data. Solution The token must be printed to browser then submitted back to server. So first of all, HtmlHelper.AntiForgeryToken() must be called in the page where the AJAX POST will be sent. Then jQuery must find the printed token in the page, and post it:$.post(url, { productName: "Tofu", categoryId: 1, __RequestVerificationToken: getToken() // Token is posted. }, callback); To be reusable, this can be encapsulated in a tiny jQuery plugin:(function ($) { $.getAntiForgeryToken = function () { // HtmlHelper.AntiForgeryToken() must be invoked to print the token. return $("input[type='hidden'][name='__RequestVerificationToken']").val(); }; var addToken = function (data) { // Converts data if not already a string. if (data && typeof data !== "string") { data = $.param(data); } data = data ? data + "&" : ""; return data + "__RequestVerificationToken=" + encodeURIComponent($.getAntiForgeryToken()); }; $.postAntiForgery = function (url, data, callback, type) { return $.post(url, addToken(data), callback, type); }; $.ajaxAntiForgery = function (settings) { settings.data = addToken(settings.data); return $.ajax(settings); }; })(jQuery); Then in the application just replace $.post() invocation with $.postAntiForgery(), and replace $.ajax() instead of $.ajaxAntiForgery():$.postAntiForgery(url, { productName: "Tofu", categoryId: 1 }, callback); // Token is posted. This solution looks hard coded and stupid. If you have more elegant solution, please do tell me.

Plan your SharePoint 2010 Content Type Hub carefully

- by Wayne

Currently setting up a new environment on SharePoint 2010 (which was made available for download yesterday if anyone missed that :-). One of the new features of SharePoint 2010 is to set up a Content Type Hub (which is a part of the Metadata Service Application), which is a hub for all Content Types that other Site Collections can subscribe to. That is you only need to manage your content types in one location. Setting up the Content Type Hub is not that difficult but you must make it very careful to avoid a lot of work and troubleshooting. Here is a short tutorial with a few tips and tricks to make it easy for you to get started. Determine location of Content Type Hub First of all you need to decide in which Site Collection to place your Content Type Hub; in the root site collection or a specific one. I think using a specific Site Collection that only acts as a Content Type Hub is the best way, there are no best practice as of now. So I create a new Site Collection, at for instance http://server/sites/CTH/. The top-level site of this site collection should be for instance a Team Site. You cannot use Blank Site by default, which would have been the best option IMHO, since that site does not have the Taxonomy feature stapled upon it (check the TaxonomyFeatureStapler feature for which site templates that can be used). Configure Managed Metadata Service Application Next you need to create your Managed Metadata Service Application or configure the existing one, Central Administration > Application Management > Manage Service Applications. Select the Managed Metadata service application and click Properties if you already have created it. In the bottom of the dialog window when you are creating the service application or when you are editing the properties is a section to fill in the Content Type Hub. In this text box fill in the URL of the Content Type Hub. It is essential that you have decided where your Content Type Hub will reside, since once this is set you cannot change it. The only way to change it is to rebuild the whole managed metadata service application! Also make sure that you enter the URL correctly. I did copy and paste the URL once and got the /default.aspx in the URL which funked the whole service up. Make sure that you only use the URL to the Site Collection of the hub. Now you have to set up so that other Site Collections can consume the content types from the hub. This is done by selecting the connection for the managed metadata service application and clicking properties. A new dialog window opens and there you need to click the Consumes content types from the Content Type Gallery at nnnn. Now you are free to syndicate your Content Types from the Hub. Publish Content Types To publish a Content Type from the hub you need to go to Site Settings > Content Types and select the content type that you would like to publish. Then select Manage publishing for this content type. This takes you to a page from where you can Publish, Unpublish or Republish the content type. Once the content type is published it can take up to an hour for the subscribing Site Collections to get it. This is controlled by the Content Type Subscriber job that is scheduled to run once an hour. To speed up your publishing just go to Central Administration > Monitoring > Review Job Definitions > Content Type Subscriber and click Run now and you content type is very soon available for use. Published Content Type status You can check the status of the content type publishing in your destination site collections by selecting Site Settings > Content Type Publishing. From here you can force a refresh of all subscribed content types, see which ones that are subscribed and finally check the publishing error log. This error log is very useful for detecting errors during the publishing. For instance if you use any features such as ratings, metadata, document ids in your content type hub and your destination site collection does not have those features available this will be reported here.

Making your WCF Web Apis to speak in multiple languages

- by cibrax

One of the key aspects of how the web works today is content negotiation. The idea of content negotiation is based on the fact that a single resource can have multiple representations, so user agents (or clients) and servers can work together to chose one of them. The http specification defines several “Accept” headers that a client can use to negotiate content with a server, and among all those, there is one for restricting the set of natural languages that are preferred as a response to a request, “Accept-Language”. For example, a client can specify “es” in this header for specifying that he prefers to receive the content in spanish or “en” in english. However, there are certain scenarios where the “Accept-Language” header is just not enough, and you might want to have a way to pass the “accepted” language as part of the resource url as an extension. For example, http://localhost/ProductCatalog/Products/1.es” returns all the descriptions for the product with id “1” in spanish. This is useful for scenarios in which you want to embed the link somewhere, such a document, an email or a page. Supporting both scenarios, the header and the url extension, is really simple in the new WCF programming model. You only need to provide a processor implementation for any of them. Let’s say I have a resource implementation as part of a product catalog I want to expose with the WCF web apis. [ServiceContract][Export]public class ProductResource{ IProductRepository repository; [ImportingConstructor] public ProductResource(IProductRepository repository) { this.repository = repository; } [WebGet(UriTemplate = "{id}")] public Product Get(string id, HttpResponseMessage response) { var product = repository.GetById(int.Parse(id)); if (product == null) { response.StatusCode = HttpStatusCode.NotFound; response.Content = new StringContent(Messages.OrderNotFound); } return product; }} The Get method implementation in this resource assumes the desired culture will be attached to the current thread (Thread.CurrentThread.Culture). Another option is to pass the desired culture as an additional argument in the method, so my processor implementation will handle both options. This method is also using an auto-generated class for handling string resources, Messages, which is available in the different cultures that the service implementation supports. For example, Messages.resx contains “OrderNotFound”: “Order Not Found” Messages.es.resx contains “OrderNotFound”: “No se encontro orden” The processor implementation bellow tackles the first scenario, in which the desired language is passed as part of the “Accept-Language” header. public class CultureProcessor : Processor<HttpRequestMessage, CultureInfo>{ string defaultLanguage = null; public CultureProcessor(string defaultLanguage = "en") { this.defaultLanguage = defaultLanguage; this.InArguments[0].Name = HttpPipelineFormatter.ArgumentHttpRequestMessage; this.OutArguments[0].Name = "culture"; } public override ProcessorResult<CultureInfo> OnExecute(HttpRequestMessage request) { CultureInfo culture = null; if (request.Headers.AcceptLanguage.Count > 0) { var language = request.Headers.AcceptLanguage.First().Value; culture = new CultureInfo(language); } else { culture = new CultureInfo(defaultLanguage); } Thread.CurrentThread.CurrentCulture = culture; Messages.Culture = culture; return new ProcessorResult<CultureInfo> { Output = culture }; }} As you can see, the processor initializes a new CultureInfo instance with the value provided in the “Accept-Language” header, and set that instance to the current thread and the auto-generated resource class with all the messages. In addition, the CultureInfo instance is returned as an output argument called “culture”, making possible to receive that argument in any method implementation The following code shows the implementation of the processor for handling languages as url extensions. public class CultureExtensionProcessor : Processor<HttpRequestMessage, Uri>{ public CultureExtensionProcessor() { this.OutArguments[0].Name = HttpPipelineFormatter.ArgumentUri; } public override ProcessorResult<Uri> OnExecute(HttpRequestMessage httpRequestMessage) { var requestUri = httpRequestMessage.RequestUri.OriginalString; var extensionPosition = requestUri.LastIndexOf("."); if (extensionPosition > -1) { var extension = requestUri.Substring(extensionPosition + 1); var query = httpRequestMessage.RequestUri.Query; requestUri = string.Format("{0}?{1}", requestUri.Substring(0, extensionPosition), query); ; var uri = new Uri(requestUri); httpRequestMessage.Headers.AcceptLanguage.Clear(); httpRequestMessage.Headers.AcceptLanguage.Add(new StringWithQualityHeaderValue(extension)); var result = new ProcessorResult<Uri>(); result.Output = uri; return result; } return new ProcessorResult<Uri>(); }} The last step is to inject both processors as part of the service configuration as it is shown bellow, public void RegisterRequestProcessorsForOperation(HttpOperationDescription operation, IList<Processor> processors, MediaTypeProcessorMode mode){ processors.Insert(0, new CultureExtensionProcessor()); processors.Add(new CultureProcessor());} Once you configured the two processors in the pipeline, your service will start speaking different languages :). Note: Url extensions don’t seem to be working in the current bits when you are using Url extensions in a base address. As far as I could see, ASP.NET intercepts the request first and tries to route the request to a registered ASP.NET Http Handler with that extension. For example, “http://localhost/ProductCatalog/products.es” does not work, but “http://localhost/ProductCatalog/products/1.es” does.

How To Get Web Site Thumbnail Image In ASP.NET

- by SAMIR BHOGAYTA

Overview One very common requirement of many web applications is to display a thumbnail image of a web site. A typical example is to provide a link to a dynamic website displaying its current thumbnail image, or displaying images of websites with their links as a result of search (I love to see it on Google). Microsoft .NET Framework 2.0 makes it quite easier to do it in a ASP.NET application. Background In order to generate image of a web page, first we need to load the web page to get their html code, and then this html needs to be rendered in a web browser. After that, a screen shot can be taken easily. I think there is no easier way to do this. Before .NET framework 2.0 it was quite difficult to use a web browser in C# or VB.NET because we either have to use COM+ interoperability or third party controls which becomes headache later. WebBrowser control in .NET framework 2.0 In .NET framework 2.0 we have a new Windows Forms WebBrowser control which is a wrapper around old shwdoc.dll. All you really need to do is to drop a WebBrowser control from your Toolbox on your form in .NET framework 2.0. If you have not used WebBrowser control yet, it's quite easy to use and very consistent with other Windows Forms controls. Some important methods of WebBrowser control are. public bool GoBack(); public bool GoForward(); public void GoHome(); public void GoSearch(); public void Navigate(Uri url); public void DrawToBitmap(Bitmap bitmap, Rectangle targetBounds); These methods are self explanatory with their names like Navigate function which redirects browser to provided URL. It also has a number of useful overloads. The DrawToBitmap (inherited from Control) draws the current image of WebBrowser to the provided bitmap. Using WebBrowser control in ASP.NET 2.0 The Solution Let's start to implement the solution which we discussed above. First we will define a static method to get the web site thumbnail image. public static Bitmap GetWebSiteThumbnail(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight) { WebsiteThumbnailImage thumbnailGenerator = new WebsiteThumbnailImage(Url, BrowserWidth, BrowserHeight, ThumbnailWidth, ThumbnailHeight); return thumbnailGenerator.GenerateWebSiteThumbnailImage(); } The WebsiteThumbnailImage class will have a public method named GenerateWebSiteThumbnailImage which will generate the website thumbnail image in a separate STA thread and wait for the thread to exit. In this case, I decided to Join method of Thread class to block the initial calling thread until the bitmap is actually available, and then return the generated web site thumbnail. public Bitmap GenerateWebSiteThumbnailImage() { Thread m_thread = new Thread(new ThreadStart(_GenerateWebSiteThumbnailImage)); m_thread.SetApartmentState(ApartmentState.STA); m_thread.Start(); m_thread.Join(); return m_Bitmap; } The _GenerateWebSiteThumbnailImage will create a WebBrowser control object and navigate to the provided Url. We also register for the DocumentCompleted event of the web browser control to take screen shot of the web page. To pass the flow to the other controls we need to perform a method call to Application.DoEvents(); and wait for the completion of the navigation until the browser state changes to Complete in a loop. private void _GenerateWebSiteThumbnailImage() { WebBrowser m_WebBrowser = new WebBrowser(); m_WebBrowser.ScrollBarsEnabled = false; m_WebBrowser.Navigate(m_Url); m_WebBrowser.DocumentCompleted += new WebBrowserDocument CompletedEventHandler(WebBrowser_DocumentCompleted); while (m_WebBrowser.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); m_WebBrowser.Dispose(); } The DocumentCompleted event will be fired when the navigation is completed and the browser is ready for screen shot. We will get screen shot using DrawToBitmap method as described previously which will return the bitmap of the web browser. Then the thumbnail image is generated using GetThumbnailImage method of Bitmap class passing it the required thumbnail image width and height. private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser m_WebBrowser = (WebBrowser)sender; m_WebBrowser.ClientSize = new Size(this.m_BrowserWidth, this.m_BrowserHeight); m_WebBrowser.ScrollBarsEnabled = false; m_Bitmap = new Bitmap(m_WebBrowser.Bounds.Width, m_WebBrowser.Bounds.Height); m_WebBrowser.BringToFront(); m_WebBrowser.DrawToBitmap(m_Bitmap, m_WebBrowser.Bounds); m_Bitmap = (Bitmap)m_Bitmap.GetThumbnailImage(m_ThumbnailWidth, m_ThumbnailHeight, null, IntPtr.Zero); } One more example here : http://www.codeproject.com/KB/aspnet/Website_URL_Screenshot.aspx

Error with my Android Application httpGet

- by Coombes

Basically I'm getting a strange issue with my Android application, it's supposed to grab a JSON Array and print out some values, the class looks like this: ShowComedianActivity.class package com.example.connecttest; public class ShowComedianActivity extends Activity{ TextView name; TextView add; TextView email; TextView tel; String id; // Progress Dialog private ProgressDialog pDialog; //JSON Parser class JSONParser jsonParser = new JSONParser(); // Single Comedian url private static final String url_comedian_details = "http://86.9.71.17/connect/get_comedian_details.php"; // JSON Node names private static final String TAG_SUCCESS = "success"; private static final String TAG_COMEDIAN = "comedian"; private static final String TAG_ID = "id"; private static final String TAG_NAME = "name"; private static final String TAG_ADDRESS = "address"; private static final String TAG_EMAIL = "email"; private static final String TAG_TEL = "tel"; public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.show_comedian); // Getting Comedian Details from intent Intent i = getIntent(); // Getting id from intent id = i.getStringExtra(TAG_ID); new GetComedianDetails().execute(); } class GetComedianDetails extends AsyncTask<String, String, String>{ protected void onPreExecute(){ super.onPreExecute(); pDialog = new ProgressDialog(ShowComedianActivity.this); pDialog.setMessage("Fetching Comedian details. Please wait..."); pDialog.setIndeterminate(false); pDialog.setCancelable(true); pDialog.show(); } @Override protected String doInBackground(String... params) { runOnUiThread(new Runnable(){ public void run(){ int success; try{ //Building parameters List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("id",id)); // Getting comedian details via HTTP request // Uses a GET request JSONObject json = jsonParser.makeHttpRequest(url_comedian_details, "GET", params); // Check Log for json response Log.d("Single Comedian details", json.toString()); //JSON Success tag success = json.getInt(TAG_SUCCESS); if(success == 1){ // Succesfully received product details JSONArray comedianObj = json.getJSONArray(TAG_COMEDIAN); //JSON Array // get first comedian object from JSON Array JSONObject comedian = comedianObj.getJSONObject(0); // comedian with id found name = (TextView) findViewById(R.id.name); add = (TextView) findViewById(R.id.add); email = (TextView) findViewById(R.id.email); tel = (TextView) findViewById(R.id.tel); // Set text to details name.setText(comedian.getString(TAG_NAME)); add.setText(comedian.getString(TAG_ADDRESS)); email.setText(comedian.getString(TAG_EMAIL)); tel.setText(comedian.getString(TAG_TEL)); } } catch (JSONException e){ e.printStackTrace(); } } }); return null; } } } And my JSON Parser class looks like: package com.example.connecttest; public class JSONParser { static InputStream is = null; static JSONObject jObj = null; static String json = ""; // constructor public JSONParser() { } // function get json from url // by making HTTP POST or GET method public JSONObject makeHttpRequest(String url, String method, List<NameValuePair> params) { // Making HTTP request try { // check for request method if(method == "POST"){ // request method is POST // defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient();

url += "?" + paramString; HttpGet httpGet = new HttpGet(url); HttpResponse httpResponse = httpClient.execute(httpGet); HttpEntity httpEntity = httpResponse.getEntity(); is = httpEntity.getContent(); } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } try { BufferedReader reader = new BufferedReader(new InputStreamReader( is, "iso-8859-1"), 8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); json = sb.toString(); } catch (Exception e) { Log.e("Buffer Error", "Error converting result " + e.toString()); } // try parse the string to a JSON object try { jObj = new JSONObject(json); } catch (JSONException e) { Log.e("JSON Parser", "Error parsing data " + e.toString()); } // return JSON String return jObj; } } Now when I run a debug it's querying the correct address with ?id=1 on the end of the URL, and when I navigate to that url I get the following JSON Array: {"success":1,"comedian":[{"id":"1","name":"Michael Coombes","address":"5 Trevethenick Road","email":"[email protected]","tel":"xxxxxxxxxxxx"}]} However my app just crashes, the log-cat report looks like this: 03-22 02:05:02.140: E/Trace(3776): error opening trace file: No such file or directory (2) 03-22 02:05:04.590: E/AndroidRuntime(3776): FATAL EXCEPTION: main 03-22 02:05:04.590: E/AndroidRuntime(3776): android.os.NetworkOnMainThreadException 03-22 02:05:04.590: E/AndroidRuntime(3776): at android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1117) 03-22 02:05:04.590: E/AndroidRuntime(3776): at libcore.io.BlockGuardOs.connect(BlockGuardOs.java:84) 03-22 02:05:04.590: E/AndroidRuntime(3776): at libcore.io.IoBridge.connectErrno(IoBridge.java:127) 03-22 02:05:04.590: E/AndroidRuntime(3776): at libcore.io.IoBridge.connect(IoBridge.java:112) 03-22 02:05:04.590: E/AndroidRuntime(3776): at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:192) 03-22 02:05:04.590: E/AndroidRuntime(3776): at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:459) 03-22 02:05:04.590: E/AndroidRuntime(3776): at java.net.Socket.connect(Socket.java:842) 03-22 02:05:04.590: E/AndroidRuntime(3776): at org.apache.http.conn.scheme.PlainSocketFactory.connectSocket(PlainSocketFactory.java:119) 03-22 02:05:04.590: E/AndroidRuntime(3776): at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:144) 03-22 02:05:04.590: E/AndroidRuntime(3776): at org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:164) 03-22 02:05:04.590: E/AndroidRuntime(3776): at org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:119) 03-22 02:05:04.590: E/AndroidRuntime(3776): at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:360) 03-22 02:05:04.590: E/AndroidRuntime(3776): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:555) 03-22 02:05:04.590: E/AndroidRuntime(3776): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:487) 03-22 02:05:04.590: E/AndroidRuntime(3776): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:465) 03-22 02:05:04.590: E/AndroidRuntime(3776): at com.example.connecttest.JSONParser.makeHttpRequest(JSONParser.java:62) 03-22 02:05:04.590: E/AndroidRuntime(3776): at com.example.connecttest.ShowComedianActivity$GetComedianDetails$1.run(ShowComedianActivity.java:89) 03-22 02:05:04.590: E/AndroidRuntime(3776): at android.os.Handler.handleCallback(Handler.java:615) 03-22 02:05:04.590: E/AndroidRuntime(3776): at android.os.Handler.dispatchMessage(Handler.java:92) 03-22 02:05:04.590: E/AndroidRuntime(3776): at android.os.Looper.loop(Looper.java:137) 03-22 02:05:04.590: E/AndroidRuntime(3776): at android.app.ActivityThread.main(ActivityThread.java:4745) 03-22 02:05:04.590: E/AndroidRuntime(3776): at java.lang.reflect.Method.invokeNative(Native Method) 03-22 02:05:04.590: E/AndroidRuntime(3776): at java.lang.reflect.Method.invoke(Method.java:511) 03-22 02:05:04.590: E/AndroidRuntime(3776): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 03-22 02:05:04.590: E/AndroidRuntime(3776): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 03-22 02:05:04.590: E/AndroidRuntime(3776): at dalvik.system.NativeStart.main(Native Method) From this I'm guessing the error is in the jsonParser.makeHttpRequest however I can't for the life of me figure out what's going wrong and was hoping someone brighter than I could illuminate me.

change an absolutely positioned webpage into a centered one

- by Jonathan

So I have this template design that is currently absolutely positioned, but I'm trying to make it centered in any widescreen browser. I've tried making the width auto on the left and right side in my container, but it is still aligned with the left side. Css .JosephSettin_png { position: absolute; left:0px; top:0px; width:216px; height:40px; background: url("JosephSettin.png") no-repeat; } .home_png { position: absolute; left:472px; top:16px; width:48px; height:16px; } .discography_png { position: absolute; left:528px; top:16px; width:80px; height:24px; } .purchase_png { position: absolute; left:608px; top:16px; width:88px; height:24px; } .about_png { position: absolute; left:696px; top:16px; width:48px; height:24px; } .contact_png { position: absolute; left:744px; top:16px; width:56px; height:24px; } .main__pic_png { position: absolute; left:0px; top:56px; width:264px; height:264px; background: url("main_pic.png") no-repeat; } .footer__lines_png { position: absolute; left:0px; top:512px; width:800px; height:24px; background: url("footer_lines.png") no-repeat; } .info__heading_png { position: absolute; left:32px; top:360px; width:216px; height:32px; background: url("info_heading.png") no-repeat; } .info__pic3_png { position: absolute; left:265px; top:360px; width:159px; height:112px; background: url("info_pic3.png") no-repeat; } .info__pic2_png { position: absolute; left:432px; top:360px; width:176px; height:112px; background: url("info_pic2.png") no-repeat; } .info__pic1_png { position: absolute; left:616px; top:360px; width:177px; height:112px; background: url("info_pic1.png") no-repeat; } .info__pane_png { position: absolute; left:0px; top:345px; width:800px; height:144px; background: url("info_pane.png") no-repeat; } body { text-align: center; background-color:maroon; } #wrapper { width: 800px; margin-left: auto; margin-right: auto; text-align: left; } #a { text-decoration: none; color:white; font-weight:bold; } .style1 { font-weight: bold; color: #FFFFFF; } html <body> <center> <div id="wrapper"> <div class="JosephSettin_png"> </div> <div class="home_png"> <a href="home.html" style="color:yellow">Home</a></div> <div class="discography_png"> <a href="discography.html">Discography</a></div> <div class="purchase_png"><a href="store.html"><span class="style1">Store</span></a></div> <div class="about_png"><a href="about.html">About</a></div> <div class="contact_png"><a href="contact.html"><span class="style1"></span>Contact</a></div> <div class="ad_png"> </div> <div class="main__pic_png"> </div> <div class="welcome__header_png"> </div> <div class="welcome__text_png"> </div> <div class="footer__lines_png"> </div> <div class="footer__text_png"> </div> <div class="info__pane_png"></div> <div class="info__heading_png"> </div> <div class="info__text_png"> </div> <div class="info__pic3_png"> </div> <div class="info__pic2_png"> </div> <div class="info__pic1_png"> </div> <div class="info__pic3_png"> </div> </div> </center> </body> I know the container I create works if all my div classes aren't absolutely positioned. Do I have to change the position or did I make another error?

log in and send sms with java

- by noobed

I'm trying to log into a site and afterwards to send a SMS (you can do that for free by the site - it's nothing more than just enter some text into some fields and 'submit'). I've used wireshark to track some of the post/get requests that my machine has been exchanging with the server - when using the browser. I'd like to paste some of my Java code: URL url; String urlP = "maccount=myRawUserName7&" + "mpassword=myRawPassword&" + "redirect_http=http&" + "submit=........"; String urlParameters = URLEncoder.encode(urlP, "CP1251"); HttpURLConnection connection = null; // Create connection url = new URL("http://www.mtel.bg/1/mm/smscenter/mc/sendsms/ma/index/mo/1"); connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("POST"); //I'm not really sure if these RequestProperties are necessary //so I'll leave them as a comment // connection.setRequestProperty("Content-Type", // "application/x-www-form-urlencoded"); // connection.setRequestProperty("Accept-Charset", "CP1251"); // connection.setRequestProperty("Content-Length", // "" + Integer.toString(urlParameters.getBytes().length)); // connection.setRequestProperty("Content-Language", "en-US"); connection.setUseCaches(false); connection.setDoInput(true); connection.setDoOutput(true); // Send request DataOutputStream wr = new DataOutputStream( connection.getOutputStream()); wr.writeBytes(urlParameters); wr.flush(); wr.close(); String headerName[] = new String[10]; int count = 0; for (int i = 1; (headerName[count] = connection.getHeaderFieldKey(i)) != null; i++) { if (headerName[count].equals("Set-Cookie")) { headerName[count++] = connection.getHeaderField(i); } } //I'm not sure if I have to close the connection here or not if (connection != null) { connection.disconnect(); } //the code above should be the login part //----------------------------------------- //this is copy-pasted from wireshark's info. String smsParam="from=men&" + "sender=0&" + "msisdn=359886737498&" + "tophone=0&" + "smstext=tova+e+proba%21+1.&" + "id=&" + "sendaction=&" + "direction=&" + "msgLen=84"; url = new URL("http://www.mtel.bg/moyat-profil-sms-tsentar_3004/" + "mm/smscenter/mc/sendsms/ma/index"); connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("POST"); connection.setRequestProperty("Cookie", headerName[0]); connection.setRequestProperty("Cookie", headerName[1]); //conn urlParameters = URLEncoder.encode(urlP, "CP1251"); connection.setUseCaches(false); connection.setDoInput(true); connection.setDoOutput(true); wr = new DataOutputStream( connection.getOutputStream()); wr.writeBytes(urlParameters); wr.flush(); wr.close(); //I'm not rly sure what exactly to do with this response. // Get Response InputStream is = connection.getInputStream(); BufferedReader rd = new BufferedReader(new InputStreamReader(is, "CP1251")); String line; StringBuffer response = new StringBuffer(); while ((line = rd.readLine()) != null) { response.append(line); response.append('\r'); } rd.close(); System.out.println(response.toString()); if (connection != null) { connection.disconnect(); } so that's my code so far. When I execute it ... I don't receive any text on my phone - so it clearly doesn't work as supposed to. I would appreciate any guidance or remarks. Is my cookie handling wrong? Is my login method wrong? Do I pass the right URLs. Do I encode and send the parameter string correctly? Is there any addition valuable data from these POSTs I should take? P.S. just in any case let me tell you that the username and password is not real. For security reasons I don't want to give valid ones. (I think this is appropriate approach) Here are the POST requests: POST /1/mm/auth/mc/auth/ma/index/mo/1 HTTP/1.1 Host: www.mtel.bg User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Referer: http://www.mtel.bg/1/mm/smscenter/mc/sendsms/ma/index/mo/1 Cookie: __utma=209782857.541729286.1349267381.1349270269.1349274374.3; __utmc=209782857; __utmz=209782857.1349267381.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); __atuvc=28%7C40; PHPSESSID=q0mage2usmv34slcv3dmd6t057; __utmb=209782857.3.10.1349274374 Content-Type: multipart/form-data; boundary=---------------------------151901450223722 Content-Length: 475 -----------------------------151901450223722 Content-Disposition: form-data; name="maccount" myRawUserName -----------------------------151901450223722 Content-Disposition: form-data; name="mpassword" myRawPassword -----------------------------151901450223722 Content-Disposition: form-data; name="redirect_https" http -----------------------------151901450223722 Content-Disposition: form-data; name="submit" ........ -----------------------------151901450223722-- HTTP/1.1 302 Found Server: nginx Date: Wed, 03 Oct 2012 14:26:40 GMT Content-Type: text/html; charset=Utf-8 Connection: close Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Location: /moyat-profil-sms-tsentar_3004/mm/smscenter/mc/sendsms/ma/index Content-Length: 0 The above text is vied with wireshark's follow tcp stream when pressing the log in button.

Trying to get around this Webservice call from Android using AsycTask

- by Kevin Rave

I am a fairly beginner in Android Development. I am developing an application that extensively relays on Webservice calls. First screen takes username and password and validates the user by calling the Webservice. If U/P is valid, then I need to fire up the 2nd activity. In that 2nd activity, I need to do 3 calls. But I haven't gotten to the 2nd part yet. In fact, I haven't completed the full coding yet. But I wanted to test if the app is working as far as I've come through. When calling webserivce, I am showing alert dialog. But the app is crashing somewhere. The LoginActivity shows up. When I enter U/P and press Login Button, it crashes. My classes: TaskHandler.java public class TaskHandler { private String URL; private User userObj; private String results; private JSONDownloaderTask task; ; public TaskHandler( String url, User user) { this.URL = url; this.userObj = user; } public String handleTask() { Log.d("Two", "In the function"); task = new JSONDownloaderTask(); Log.d("Three", "In the function"); task.execute(URL); return results; } private class JSONDownloaderTask extends AsyncTask<String, Void, String> { private String username;// = userObj.getUsername(); private String password; //= userObj.getPassword(); public HttpStatus status_code; public JSONDownloaderTask() { Log.d("con", "Success"); this.username = userObj.getUsername(); this.password = userObj.getPassword(); Log.d("User" + this.username , " Pass" + this.password); } private AsyncProgressActivity progressbar = new AsyncProgressActivity(); @Override protected void onPreExecute() { progressbar.showLoadingProgressDialog(); } @Override protected String doInBackground(String... params) { final String url = params[0]; //getString(R.string.api_staging_uri) + "Authenticate/"; // Populate the HTTP Basic Authentitcation header with the username and password HttpAuthentication authHeader = new HttpBasicAuthentication(username, password); HttpHeaders requestHeaders = new HttpHeaders(); requestHeaders.setAuthorization(authHeader); requestHeaders.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON)); // Create a new RestTemplate instance RestTemplate restTemplate = new RestTemplate(); restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter()); try { // Make the network request Log.d(this.getClass().getName(), url); ResponseEntity<Message> response = restTemplate.exchange(url, HttpMethod.GET, new HttpEntity<Object>(requestHeaders), Message.class); status_code = response.getStatusCode(); return response.getBody().toString(); } catch (HttpClientErrorException e) { status_code = e.getStatusCode(); return new Message(0, e.getStatusText(), e.getLocalizedMessage(), "error").toString(); } catch ( Exception e ) { Log.d(this.getClass().getName() ,e.getLocalizedMessage()); return "Unknown Exception"; } } @Override protected void onPostExecute(String result) { progressbar.dismissProgressDialog(); switch ( status_code ) { case UNAUTHORIZED: result = "Invalid username or passowrd"; break; case ACCEPTED: result = "Invalid username or passowrd" + status_code; break; case OK: result = "Successful!"; break; } } } } AsycProgressActivity.java public class AsyncProgressActivity extends Activity { protected static final String TAG = AsyncProgressActivity.class.getSimpleName(); private ProgressDialog progressDialog; private boolean destroyed = false; @Override protected void onDestroy() { super.onDestroy(); destroyed = true; } public void showLoadingProgressDialog() { Log.d("Here", "Progress"); this.showProgressDialog("Authenticating..."); Log.d("Here", "afer p"); } public void showProgressDialog(CharSequence message) { Log.d("Here", "Message"); if (progressDialog == null) { progressDialog = new ProgressDialog(this); progressDialog.setIndeterminate(true); } Log.d("Here", "Message 2"); progressDialog.setMessage(message); progressDialog.show(); } public void dismissProgressDialog() { if (progressDialog != null && !destroyed) { progressDialog.dismiss(); } } } LoginActivity.java public class LoginActivity extends AsyncProgressActivity implements OnClickListener { Button login_button; HttpStatus status_code; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //this.requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.main); login_button = (Button) findViewById(R.id.btnLogin); login_button.setOnClickListener(this); ViewServer.get(this).addWindow(this); } public void onDestroy() { super.onDestroy(); ViewServer.get(this).removeWindow(this); } public void onResume() { super.onResume(); ViewServer.get(this).setFocusedWindow(this); } public void onClick(View v) { if ( v.getId() == R.id.btnLogin ) { User userobj = new User(); String result; userobj.setUsername( ((EditText) findViewById(R.id.username)).getText().toString()); userobj.setPassword(((EditText) findViewById(R.id.password)).getText().toString() ); TaskHandler handler = new TaskHandler(getString(R.string.api_staging_uri) + "Authenticate/", userobj); Log.d(this.getClass().getName(), "One"); result = handler.handleTask(); Log.d(this.getClass().getName(), "After two"); Utilities.showAlert(result, LoginActivity.this); } } Utilities.java public class Utilities { public static void showAlert(String message, Context context) { AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context); alertDialogBuilder.setTitle("Login"); alertDialogBuilder.setMessage(message) .setCancelable(false) .setPositiveButton("OK",new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog,int id) { dialog.dismiss();
