  • How does this Singleton-like web class persists session data, even though session is not updated in

    - by Micah Burnett
    Ok, I've got this singleton-like web class which uses session to maintain state. I initially thought I was going to have to manipulate the session variables on each "set" so that the new values were updated in the session. However I tried using it as-is, and somehow, it remembers state. For example, if run this code on one page: UserContext.Current.User.FirstName = "Micah"; And run this code in a different browser tab, FirstName is displayed correctly: Response.Write(UserContext.Current.User.FirstName); Can someone tell me (prove) how this data is getting persisted in the session? Here is the class: using System; using System.Collections.Generic; using System.Linq; using System.Web; public class UserContext { private UserContext() { } public static UserContext Current { get { if (System.Web.HttpContext.Current.Session["UserContext"] == null) { UserContext uc = new UserContext(); uc.User = new User(); System.Web.HttpContext.Current.Session["UserContext"] = uc; } return (UserContext)System.Web.HttpContext.Current.Session["UserContext"]; } } private string HospitalField; public string Hospital { get { return HospitalField; } set { HospitalField = value; ContractField = null; ModelType = null; } } private string ContractField; public string Contract { get { return ContractField; } set { ContractField = value; ModelType = string.Empty; } } private string ModelTypeField; public string ModelType { get { return ModelTypeField; } set { ModelTypeField = value; } } private User UserField; public User User { get { return UserField; } set { UserField = value; } } public void DoSomething() { } } public class User { public int UserId { get; set; } public string FirstName { get; set; } } I added this to a watch, and can see that the session variable is definitely being set somewhere: (UserContext)System.Web.HttpContext.Current.Session["UserContext"]; As soon as a setter is called the Session var is immediately updated: set { HospitalField = value; //<--- here ContractField = null; ModelType = null; }

  • API for accessing PHP documentation?

    - by Chad Johnson
    I'm done some Googling, and I've found nothing. I'm scoping out writing a plugin for an editor I use, and I am wondering whether there is a way I can access the PHP documentation via an API? For instance, I'd like to get raw access to the information (besides the comments) located here: http://php.net/file_exists. php.net seemingly uses MediaWiki which provides an API. The tutorial provides the example URL, http://en.wikipedia.org/w/api.php?action=login&format=xml. This does not work for php.net, however (http://php.net/w/api.php?action=login&format=xml). I'm just looking for a little information on how to interface with the PHP documentation.

  • What is a Web Framework ? How does it compare with LAMP

    - by Nishant
    I started web development in LAMP/WAMP and it was logical to me . There is a Web Server program called Apache which does the networking part of setting up a service on port 80 ( common port ) . If the request is regular HTML it uses the HTTP headers to transport files .And if the request for the file is a PHP one , it has a mod_php with which Apache invokes the PHP interpreter to process the file and it gives back HTML which is again transferred as usual HTML . Now the question is what is a Web Framework ? I came across Python based website creation and there is Flask . What is a flask , how does it compare with LAMP . Further are DJango / Ruby on Rails different from flask ? Can someone answer me and also give some good places to read on these .Thanks for your answers in advance . Further is things like LAMP slower than the common FRAMEWORKS because they claimn easy deplyment fo web apps .

  • Authentication and authorization for RESTfull API (java jersery)

    - by abovesun
    Hi, implementing service something similar with tinyurl or bit.ly, I'm would like to expose service as API, I'm using java and jersey as RESTfull service implementation. I'm looking for simplest way for authentification of users who use API, OAuth is first thing coming in mind, but the problem is I don't need this 3 iteration calls with request token query, than access token query with callback url passing. I just need to give user ability to invoke api with no additional security calls to my server.

  • Offline Mapping API

    - by Aaron M
    Are there any services available that allow me to manipulate maps in an offline setting? I am working on a project that requires me to take a map and based on features on the map, generate a game world. I have looked at a few of the API's for different providers: Google, ms, etc. The API's I looked seem to be strictly showing a user a map. I am looking for something that allows me to create a derivative of a map (the Gameworld), that will never be seen by the public, and is only used by the game engine. However one caveat is that I would like to be able to link the derivative created for use by the game engine, with something I can show the user. As an example. Think of a cross country racing sim. Users cannot control the vehicles directly in this game, they can only control the cars setup, driver, etc. I create a gameworld from a map. The gameworld data (driver position, etc) is overlayed onto a real map. A race might last several days. The only interaction users have with the real map is viewing their position on the map, and where they are in relation to the others. I don't want to violate the terms of the API here. I read Googles API TOS, and it seems to me that creating the gameworld would violdate their TOS. The features I really need are the following The ability to locate a specific place on the map by lat/long The ability/rights to grab those maps and save them as an image file temporarily for processing The ability/rights to store a gameworld that is based on the real map The ability to show a user a map with an overlay (this is optional. I can use googles API, or any other one that supports lat/long.)

  • JavaScript method to write to Microsoft Visual Web Developer Debugger?

    - by Josh
    I generally test my web apps with Firefox and use Firebug. I love Firebug. But when I'm testing JavaScript code in IE I use the debugger in Microsoft's Visual Web Developer 2008 Express Edition. I would love to have an equivalent to Firebug's console.log methods which would allow me to log messages to Visual Web Developer. Any way to log messages to the error list/messages list/output pane using JavaScript?

  • Java preferences API throughput

    - by Domchi
    I'm using Java Preferences API to store window position and size of Swing application. At this moment, I'm listening to window resize/reposition events and storing the position and size every time they change. However, that means that if user slowly resizes window which is 200px wide to 400px wide, I'll probably write new window size about 200 times during pretty short time. Preferences API uses whichever datastore is available on the host system (windows registry for Windows etc.) - but the question is, what are limitations or best practices for properties API? Is it OK, or would it be smart to write only when user has finished resizing? Anyone had experiences with Properties API on different platforms?

  • Running Endpoint locally could not provide access to API explorer when HTTP proxy is enabled

    - by harik
    I'm using Android Studio(0.5.8) on Window7 x64 for developing my Android App with Google AppEngine backend. If my machine is having direct internet access and I launch backend locally (as DevApp Server) and access my API Endpoints through webbrowser (chrome) it is all working as expected. Accessing api explorer is also working fine from webbrowser. http://localhost:8080/_ah/api/explorer But if I have configured internet through http proxy (in Android Studio and also in webbrowser) then webbrowser displays initial page of backend but can't access endpoint api explorer. And deploying appbackend in Google AppEngine also fails with errors. gradlew backend:appengineUpdate Same is working fine if direct internet access is available (not via http proxy). How can we make it work with http proxy also? Any help is appreciated, Thanks.

  • Maven dependency for Servlet 3.0 API?

    - by deamon
    How can I tell Maven 2 to load the Servlet 3.0 API? I tried: <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>3.0</version> <scope>provided</scope> </dependency> I use http://repository.jboss.com/maven2/ but what repository would be correct? Addendum: It works with a dependency for the entire Java EE 6 API and the following settings: <repository> <id>java.net</id> <url>http://download.java.net/maven/2</url> </repository> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> I'd prefer to only add the Servlet API as dependency, but "Brabster" may be right that separate dependencies have been replaced by Java EE 6 Profiles. Is there a source that confirms this assumption?

  • Register new memer for vBulletin via Mobile API

    - by Nikolay Stariradeff
    I'm trying to use the vBulletin REST Mobile API to simply register. The sourced are installed on my local machine and according the documentation https://www.vbulletin.com/forum/content.php/393-User-Registration-Process-Mobile-API This procedure should not be so hard, especially without humanity and COPPA authentication. However I've stacked! The method definition describes "addnewmember" clear, so I've generated a test link, which should do the job. https://www.vbulletin.com/forum/content.php/365-User-Related-Methods The link is: .../forum/api.php?&api_m=register_addmember&api_c=1&api_s=76ec9eec61e7fdfef2f3feee28d5f392&api_sig=8fe54313b333cc0fef4ddd8e398b5c80&api_v=6&agree=1&username=testuser&email=XXXXXX%40gmail.com&emailconfirm=XXXXX%40gmail.com&password=12345678&passwordconfirm=12345678 As a response I get: register_not_agreed The Docs: register_not_agreed The agree parameter should be set to 1. Which is also clear - agree parameter was not there. Here comes the funny part - In the API-Log I can see that the 'agree' parameter is correctly passed *1 test_client Gast 13:23, 18.06.2012 register_addmember Array ( [api_m] = register_addmember [api_c] = 1 [api_s] = 76ec9eec61e7fdfef2f3feee28d5f392 [api_sig] = 8fe54313b333cc0fef4ddd8e398b5c80 [api_v] = 6 [agree] = 1 [username] = testuser [email] = ....* Is there anybody with experience with the Mobile API that could help?

  • Clean install of IIS 6 on Windows Server 2003 ignoring 'web.config'?

    - by Vario
    Hi, Any help with this would be really appreciated! As the title suggests, I'm running a brand new install of Windows Server 2003 and IIS 6 and I'm basically attempting to mirror a live web server onto a new internal development server, which runs the same setup. It's an ASP.NET site that relies heavily on URL rewriting (using Intelligencia). ASP.NET is set to run on v2.0.50727 on both servers. I've tried intentionally introduce syntax errors into the web.config and it just appears to be ignoring them completely, so given IIS 6 doesn't read the web.config, the rest of the site doesn't work at all (I get a 404 error, as a 'Default.aspx' doesn't exist since the web.config handles the default page rewriting). Having looked at the Application Mapping, '.config' files are set to use the default 'c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll' which exists. Is there anything else I may be missing? Thanks in advance.

  • Whats a good API for generating reports for a java web application?

    - by Ahmad
    I have a J2EE application that has a lot of reports, the situation now is the following: Report filters' values are sent to the application over DWR mainly, the data are retrieved from Oracle DB throw DB procedures and returned back to the client. However, some customization is required every now and then (new data filters, columns, ordering, ...), and these changes are painful to implement since we need to modify the JSPs, DB Procedures, the application itself, ... What API do you recommend to use for such reports?

  • Why can't i create a RESTful web service in ejb module?

    - by Nitesh Panchal
    Hello, I am using Netbeans 6.8. I can see an option to create a web service in my independent ejb module but i can't seem to find an option to create a RESTful based web service in my ejb module. Is there any kind of restriction in ejb module that i can only create SOAP based web service and not RESTful? or is it the bug of Netbeans 6.8?

  • Twitter API + OAuth - 401 error developing locally using reverse SSH tunnel

    - by oliland
    I'm developing a django application which lets users connect their Twitter account. As I'm developing locally, I have set up a reverse SSH tunnel so that the Twitter API has a valid callback url (myserver.net): ssh -nNTR :6969:localhost:8000 myserver.net On successful authentication, Twitter passes back its OAuth access tokens to myserver.net, which in turn attempts to access Twitter's API, which returns a 401 error. I assume that because the callback is different to the address which is accessing the API (myserver.net / localhost), Twitter denies me access. I have tried this: export http_proxy="http://myserver.net:3128" Where myserver.net:3128 is running a Squid Proxy server to tunnel Twitter's API requests from my development machine so they appear to be coming from myserver, but receive the same 401 error. When I deploy to a server with a proper hostname / static IP address it works fine. What else do I need to do?

  • .net example of using client certificates in web service call?

    - by Rory
    I'd like to use client certificates to verify the identity of administrative callers to my web service. Then I can issue certificates only to the people I want to call my web service and be pretty sure noone else can call it. This is in a very controlled scenario where only one or two people will get the client certificate, so distribution isn't a hard problem. This article provides a good example of how to call a web service using a client certificate. But how can I check details of the client certificate from within my web service? This old article talks about configuring IIS to do it, but I'd like to do it programmatically within my app. I think? thanks for any suggestions!

  • Web.xml: Are url-pattern tags relative to each other?

  • Anyone NOT using a Web Framework? Why?

    - by tom
    I'm well aware of the many reasons to use a web framework. I'm just wondering whether anyone out there is using absolutely no web framework whatsoever to develop their web projects. I would really love to know the reason(s) why you're not using a web framework. For the sake of this discussion, your programming language of choice does not matter. Some possibilities for discussion: You don't hide behind an ORM. You don't rely on any sort of templating system. You think MVC is a really nice TLA but lacks an essential vowel or two. No need for any additional javascript framework tomfoolery. You just write as much code as possible in your native programming language(s). Summary of reasons thus far: Language learning opportunities. Specific performance reasons (write-intensive transaction processing). Seeking more nuanced control over your data and applications (less abstraction). You're building your own framework! Prove to yourself that you can succeed (or fail) just like the big framework-building gurus. Integration issues with unpopular/legacy technologies (exotic databases or protocols come to mind). Big company, lots of code, no talent nor buy-in present to move to a web framework. Some frameworks really lock you in and cannot perpetually grow along with your needs. These few black sheep don't make it easy to jump outside of the framework, write some custom code, and easily jump back in. When you finally escape the asylum, you'll never look back.

  • Getting list of Facebook friends with latest API

    - by Eric
    I'm using the most recent version of the Facebook SDK (which lets to connect to something called the 'graph API' though I'm not sure). I've adapted Facebook's example code to let me connect to Facebook and that works... but I can't get a list of my friends. $friends = $facebook->api('friends.get'); This produces the error message: "Fatal error: Uncaught OAuthException: (#803) Some of the aliases you requested do not exist: friends.get thrown in /mycode/facebook.php on line 543" No clue why that is or what that means. Can someone tell me the right syntax (for the latest Facebook API) to get a list of friends? (I tried "$friends = $facebook-api-friends_get();" and get a different error, "Fatal error: Call to a member function friends_get() on a non-object in /mycode/example.php on line 129".) I can confirm that BEFORE this point in my code, things are fine: I'm connected to Facebook with a valid session and I can get my info and dump it to the screen just... i.e. this code executes perfectly before the failed friends.get call: $session = $facebook->getSession(); if ($session) { $uid = $facebook->getUser(); $me = $facebook->api('/me'); } print_r($me);

  • Bing search API and Azure

    - by Gapton
    I am trying to programatically perform a search on Microsoft Bing search engine. Here is my understanding: There was a Bing Search API 2.0 , which will be replaced soon (1st Aug 2012) The new API is known as Windows Azure Marketplace. You use different URL for the two. In the old API (Bing Search API 2.0), you specify a key (Application ID) in the URL, and such key will be used to authenticate the request. As long as you have the key as a parameter in the URL, you can obtain the results. In the new API (Windows Azure Marketplace), you do NOT include the key (Account Key) in the URL. Instead, you put in a query URL, then the server will ask for your credentials. When using a browser, there will be a pop-up asking for a/c name and password. Instruction was to leave the account name blank and insert your key in the password field. Okay, I have done all that and I can see a JSON-formatted results of my search on my browser page. How do I do this programmatically in PHP? I tried searching for the documentation and sample code from Microsoft MSDN library, but I was either searching in the wrong place, or there are extremely limited resources in there. Would anyone be able to tell me how do you do the "enter the key in the password field in the pop-up" part in PHP please? Thanks alot in advance.
