  • WCF ReliableMessaging method called twice

    - by Brian
    Using Fiddler, we see 3 HTTP requests (and matching responses) for each call when: WS-ReliableMessaging is enabled, and, the method returns a large amount of data (17MB) The first HTTP request is a SOAP message with the action "CreateSequence" (presumable to establish the reliable session). The second and third HTTP requests are identical SOAP messages invoking our webservice method. Why are there two identical messages? Here is our config: <system.serviceModel> <client> <endpoint address="http://server/vdir/AccountingService.svc" binding="wsHttpBinding" bindingConfiguration="customWsHttpBinding" behaviorConfiguration="LargeServiceBehavior" contract="MyProject.Accounting.IAccountingService" name="BasicHttpBinding_IAccountingService" /> </client> <bindings> <wsHttpBinding> <binding name="customWsHttpBinding" maxReceivedMessageSize="90000000"> <reliableSession enabled="true"/> <security mode="None" /> </binding> </wsHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name="LargeServiceBehavior"> <dataContractSerializer maxItemsInObjectGraph="2147483647"/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> Thanks, Brian

  • ASP.NET MVC 2 router matches correct area route but generates URL to the first registered area inste

    - by Sandor Drieënhuizen
    I'm working on a S#arpArchitecture 1.5 project, which uses ASP.NET MVC 2. I've been trying to get areas to work properly but I ran into a problem: The ASP.NET MVC 2 routing engine matches the correct route to my area but then it generates an URL that belongs to the first registered area instead. Here's my request URL: /Framework/Authentication/LogOn?ReturnUrl=%2fDefault.aspx I'm using the Route Tester from Phil Haack and it shows: Matched Route: Framework/{controller}/{action}/{id} Generated URL: /Data/Authentication/LogOn?ReturnUrl=%2FDefault.aspx using the route "Data/{controller}/{action}/{id}" That's clearly wrong, the URL should point to the Framework area, not the Data area. This is how I register my routes, nothing special there IMO. private static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); AreaRegistration.RegisterAllAreas(); routes.MapRoute( "default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = UrlParameter.Optional }); } The area registration classes all look like this. Again, nothing special. public class FrameworkAreaRegistration : AreaRegistration { public override string AreaName { get { return "Framework"; } } public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Framework_default", "Framework/{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = UrlParameter.Optional }); } }

  • onmouseover with django / imagekit

    - by Michael Moreno
    I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

  • MVC ASP.NET, ObjectContext and Ajax. Weird Behaviour

    - by fabianadipolo
    Hi, i've been creating a web application in mvc asp.net. I have three different project/solutions. One solution contains the model in EF (DAL) and all the methods to add, update, delete and query the objects in the model, the objectcontext is managed here in a per request basis. Other solution contains a content management system in wich authorized users insert, delete, update and access objects through the DAL mentioned before. And the last solution contains the web page that is accessed by all users and where the only operations executed are selects, no update, inserts or deletes here. All the selects are executed against the DAL mentioned before (the first solution). The problem here is that i'm not sure whether an HttpContext lifespan ObjectContext is the best solution. I have a lot of ajax calls in my web app and i'm not sure if an httpcontext could interfere with the performance of the application. I've been noticed that in some cases, specially when someone is working in the content manager inserting, updating or deleting, when you try to click on any link of the user web application (the web app that is accessed by any user - the third one that i mentioned before) the web page freezes and it remains stucked transferring data. In order to stop that behaviour you have to stop and refresh or click several times on the link. Excuse me for my bad english. I hope you could understand and could help me to solve this issue. Thanx in advance.

  • Facebook events api: Event member (FQL)

    - by sunil-khedar
    I am fetching the event members for facebook events. Till yesterday I was getting the proper counts of members of an event. But suddenly the counts have following issues: For lot of plans on every consecutive request, I am getting random number of members. Strange issue. Seems facebook servers are not synced properly or something similar. Earlier for the same query string (mentioned below), I was getting the correct counts. But now the count is much less. It seems that at least for a few events now they are sending only the members who are connected with our application (we are using facebook connect). Example: for the following query currently I am getting "31" members. But on event page members count is much more. FQL: FB.Facebook.apiClient.fql_query('SELECT uid, eid, rsvp_status FROM event_member WHERE eid=336671213618', function(result, error){alert(result.length);}); Event page: http://www.facebook.com/event.php?eid=109411842404023 Is there any recent change in facebook API or policies? Thanks in advance.

  • How to Increase the time till a read timeout error occurs?

    - by Alex
    Hi all. I've written in PHP a script that takes a long time to execute [Image processing for thousands of pictures]. It's a meter of hours - maybe 5. After 15 minutes of processing, I get the error: ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: The URL which I clicked Read Timeout The system returned: [No Error] A Timeout occurred while waiting to read data from the network. The network or server may be down or congested. Please retry your request. Your cache administrator is webmaster. What I need is to enable that script to run for much longer. Now, here are all the technical info: I'm writing in PHP and using the Zend Framework. I'm using Firefox. The long script that is processed is done after clicking a link. Obviously, since the script is not over I see the web page on which the link was and the web browser writes "waiting for ...". After 15 minutes the error occurs. I tried to make changes to Firefox threw about:config but without any success. I don't know, but the changes might be needed somewhere else. So, any ideas? Thanks ahead.

  • Servlet receives null from Remote EJB3 Session Bean

    - by Hank
    I'm sure this is a beginner error... So I have a JEE6 application with entities, facades (implementing the persistence layer) and Stateless Session Beans (EJB3) with Remote interfaces (providing access to the entities via facades). This is working fine. Via the SLSB I can retrieve and manipulate entities. Now, I'm trying to do this from a Web Application (deployed on the same Glassfish, entity+interface definitions from JEE app imported as separate jar). I have a Servlet, that receives an instance of the SLSB injected. I get it to retrieve an entity, and the following happens (I can see it in the logs): the remote SLSB gets instantiated, its method called SLSB instantiates the facade, calls the 'get' method facade retrieves object from DB, returns it SLSB returns the object to the caller (all is good until here) calling servlet receives .. null !! What is going wrong? This should work, right? MyServlet: public class MyServlet extends HttpServlet { @EJB private CampaignControllerRemote campaignController; // remote SLSB protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/plain"); PrintWriter out = response.getWriter(); try { Campaign c = campaignController.getCampaign(5L); // id of an existing campaign out.println("Got "+ c.getId()); // c is null !! } finally { out.close(); } } ... } Pls let me know if you want to see other code, and I'll update the post.

  • HttpURLConnection: What is the minimum best-practice implementation?

    - by stormin986
    I've come across a lot of HttpURLConnection examples that are nothing more than openConnection(), getInputStream(), and then they just read the buffer and are done. It's simple but seems like it's not the best implementation ... it handles no problems. I don't yet know much about http, so I keep thinking I have everything covered until a new problem arises. I'm currently experiencing a similar problem to this one. Most times I try to read the same resource a second time (from a different HttpURLConnection object, after I .disconnect()'ed the previous one), the response code returns as -1 (but no exception is thrown!!). Before I knew to check the response code, I was baffled since I was throwing no exceptions. So, is there a minimum 'best practice' HttpURLConnection implementation? What are notable exceptions to handle? Request code checking? Any other error checks? What connection parameters do and don't need to be set (like doInput / doOutput, are these even necessary? Some examples have em, some don't). Etc. I realize this is kind of a broad question but I think it has potential to be a very useful resource if many of the common use cases and FAQs are addressed in one central place. This seems like the kind of thing a community wiki would be good for...

  • Spring-json problem in Liferay with Spring 2.5

    - by Jesus Benito
    Hi all, I am trying to use the library spring-json.1.3.1 in a project that has been done with Liferay 5.1.2 which includes Spring 2.5. Following the project website instructions, I managed to make the request hit in my controller, but at the moment of returning the json object back through the modelAndView object it fails with the following error: java.lang.IllegalArgumentException at com.liferay.portlet.MimeResponseImpl.setContentType(MimeResponseImpl.java:162) I have checked Liferays source code, and it checks that contentType that its being set is in a harcoded list,if it not it will throw a IllegalArgumentException that it is exactly what os happening. This is my view resolver code: <bean id="xmlFileViewResolver" class="org.springframework.web.servlet.view.XmlViewResolver"> /WEB-INF/context/views.xml 1 My views.xml code: <beans> <bean name="jsonView" class="org.springframework.web.servlet.view.json.JsonView"/> And my controller: @SuppressWarnings("unchecked") @Override public ModelAndView handleRenderRequest(RenderRequest arg0, RenderResponse arg1) throws Exception { Map model = new HashMap(); model.put("firstname", "Peter"); model.put("secondname", "Schmitt"); return new ModelAndView("jsonView", model); } Any ideas?

  • RESTful WCF Data Service Authentication

    - by Adrian Grigore
    Hi, I'd like to implement a REST api to an existing ASP.NET MVC website. I've managed to set up WCF Data services so that I can browse my data, but now the question is how to handle authentication. Right now the data service is secured via the site's built in forms authentication, and that's ok when accessing the service from AJAX forms. However, It's not ideal for a RESTful api. What I would like as an alternative to forms authentication is for the users to simply embed the user name and password into the url to the web service or as request parameters. For example, if my web service is usually accessible as http://localhost:1234/api.svc I'd like to be able to access it using the url http://localhost:1234/api.svc/{login}/{password} So, my questions are as follows: Is this a sane approach? If yes, how can I implement this? It seems trivial redirecting GET requests so that the login and password are attached as GET parameters. I also know how to inspect the http context and use those parameters to filter the results. But I am not sure if / how the same approach could be applied to POST, PUT and DELETE requests. Thanks, Adrian

  • Strange error coming from ActiveRecord (probably)

    - by artemave
    My development environment: Ubuntu 9 Ruby 1.9.1/1.8.7 (rvm) Rails 2.3.5 Mysql 5.0 Apache Passenger Below is the part of the program flow to represent the issue. Request comes: #action def create begin @report = Report.new(params[:report]) ... rescue LocationNotFound => e ... end end Report constructor: class Report attr_accessor :locations def initialize(params = {}) @locations = params[:locations] ? fetch_locations(params[:locations]) : [] end ... end fetch_locations: def fetch_locations(loc_names) Rails.logger.debug "LOC_NAMES: " + loc_names.inspect ls = Location.find(:all, :conditions => [ # line 57 "locations.name in (#{loc_names.map{'?'}.join(',')})", *loc_names ], :include => [:sample_summaries, :samples]) # loc_names will never be empty ... end Location model: class Location < ActiveRecord::Base has_many :sample_summaries has_many :samples, :through => :sample_summaries ... end Now, the first time (after passenger restart) this runs fine and does the job. Most of the consequent times I get the error: Mar-11 11:01:00 #15098 DEBUG: LOC_NAMES: ["Moscow, RF", "London, UK"] Mar-11 11:01:00 #15098 DEBUG: Location Load (0.0ms) SELECT * FROM `locations` WHERE (locations.name in ('Moscow, RF','London, UK')) Mar-11 11:01:00 #15098 DEBUG: SampleSummary Load (0.0ms) SELECT `sample_summaries`.* FROM `sample_summaries` WHERE (`sample_summaries`.location_id IN (1,3)) Mar-11 11:01:00 #15098 DEBUG: SampleSummary Columns (0.0ms) SHOW FIELDS FROM `sample_summaries` Mar-11 11:01:00 #15098 FATAL: NoMethodError (You have a nil object when you didn't expect it!

  • ASP.Net GridView UpdatePanel Paging Gives Error On Second Click

    - by joe
    I'm trying to implement a GridView with paging inside a UpdatePanel. Everything works great when I do my first click. The paging kicks in and the next set of data is loaded quickly. However, when I then try to click a link for another page of data, I get the following error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server.

  • Best way to change jqGrid rowNum from ALL to -1 before pass to a web service

    - by Billyhole
    I'm looking to find the best way to allow users to choose to show ALL records in a jqGrid. I know that a -1 value passed for the rows parameter denotes ALL, but I want the word "ALL" not a -1 to appear in the rowList select element, ie. rowList: [15, 50, 100, 'ALL']. I'm passing the grid request to a web service which accepts an int for "rows", and I'm trying find how and when I should change the user selected value of "ALL" to a -1 before it gets sent to the web service. Below is my cleaned up grid code. I tried some various code blocks before my $.ajax in the datatype function. But most attempts just seemed like I have to be doing this the most convoluted way I possibly could. For example, datatype: function(postdata) { if ($("#gridTableAssets").jqGrid('getGridParam', 'rowNum') == 'ALL') { $("#gridTableAssets").appendPostData({ "rows": -1, "page": 1 }); } $.ajax({... But doing that seemed to cause the actual "page" GridParam to be nulled out on subsequent grid actions, forcing me handle that in other places. There just seems like this is something that would be frequently done out there and have clean way of doing it. Cleaned grid code: $("#gridTableAssets").jqGrid({ datatype: function(postdata) { $.ajax({ url: "/Service/Repository.asmx/GetAssets", data: JSON.stringify(postdata), type: 'POST', contentType: "application/json; charset=utf-8", error: function(XMLHttpRequest, textStatus, errorThrown) { alert('error'); }, success: function(msg) { var assetsGrid = $("#gridTableAssets")[0]; assetsGrid.addJSONData(JSON.parse(msg)); ... } }); }, ... pager: $('#pagerAssets'), rowNum: 15, rowList: [15, 50, 100, 'ALL'], ... onPaging: function(index, colindex, sortorder) { SessionKeepAlive(); } }); And here is the web service [WebMethod] public string GetAssetsOfAssetStructure(bool _search, int rows, int page, string sidx, string sord, string filters)

  • htaccess mod_rewrite check file/directory existence, else rewrite?

    - by devians
    I have a very heavy htaccess mod_rewrite file that runs my application. As we sometimes take over legacy websites, I sometimes need to support old urls to old files, where my application processes everything post htaccess. My ultimate goal is to have a 'Demilitarized Zone' for old file structures, and use mod rewrite to check for existence there before pushing to the application. This is pretty easy to do with files, by using: RewriteCond %{IS_SUBREQ} true RewriteRule .* - [L] RewriteCond %{ENV:REDIRECT_STATUS} 200 RewriteRule .* - [L] RewriteCond Public/DMZ/$1 -F [OR] RewriteRule ^(.*)$ Public/DMZ/$1 [QSA,L] This allows pseudo support for relative urls by not hardcoding my base path (I cant assume I will ever be deployed in document root) anywhere and using subrequests to check for file existence. Works fine if you know the file name, ie http://domain.com/path/to/app/legacyfolder/index.html However, my legacy urls are typically http://domain.com/path/to/app/legacyfolder/ Mod_Rewrite will allow me to check for this by using -d, but it needs the complete path to the directory, ie RewriteCond Public/DMZ/$1 -F [OR] RewriteCond /var/www/path/to/app/Public/DMZ/$1 -d RewriteRule ^(.*)$ Public/DMZ/$1 [QSA,L] I want to avoid the hardcoded base path. I can see one possible solutions here, somehow determining my path and attaching it to a variable [E=name:var] and using it in the condition. Another option is using -U, but the tricky part is stopping it from hijacking every other request when they should flow through, since -U is really easy to satisfy. Any implementation that allows me to existence check a directory is more than welcome. I am not interested in using RewriteBase, as that requires my htaccess to have a hardcoded base path.

    Hi There, I ahave some ajax that is fired when a checkbox is clicked, it essentially sends a query string to a PHP script and then returns the relevant HTML, however, if I select a select it works fine if I then slect another checkbox as well as the previous I get no activity what so ever, not even any errors in firebug, it is very curious, does anyone have any ideas? //Location AJAX //var dataObject = new Object(); var selected = new Array(); //alert(selected); $('#areas input.radio').change(function(){ // will trigger when the checked status changes var checked = $(this).attr("checked"); // will return "checked" or false I think. // Do whatever request you like with the checked status if(checked == true) { //selected.join('&'); selected = $('input:checked').map(function() { return $(this).attr('name')+"="+$(this).val(); }).get(); getQuery = selected.join('&')+"&location_submit=Next"; alert(getQuery); $.ajax({ type:"POST", url:"/search/location", data: getQuery, success:function(data){ //alert(getQuery); //console.log(data); $('body.secEmp').html(data); } }); } else { //do something to remove the content here alert($(this).attr('name')); } });

  • Proper use of HTTP status codes in a "validation" server

    - by Romulo A. Ceccon
    Among the data my application sends to a third-party SOA server are complex XMLs. The server owner does provide the XML schemas (.xsd) and, since the server rejects invalid XMLs with a meaningless message, I need to validate them locally before sending. I could use a stand-alone XML schema validator but they are slow, mainly because of the time required to parse the schema files. So I wrote my own schema validator (in Java, if that matters) in the form of an HTTP Server which caches the already parsed schemas. The problem is: many things can go wrong in the course of the validation process. Other than unexpected exceptions and successful validation: the server may not find the schema file specified the file specified may not be a valid schema file the XML is invalid against the schema file Since it's an HTTP Server I'd like to provide the client with meaningful status codes. Should the server answer with a 400 error (Bad request) for all the above cases? Or they have nothing to do with HTTP and it should answer 200 with a message in the body? Any other suggestion? Update: the main application is written in Ruby, which doesn't have a good xml schema validation library, so a separate validation server is not over-engineering.

  • Loading GMaps via ajax

    - by Marco
    Hi to all, I'm loading a page containing a GMaps using the ajax() method of jQuery. The HTML page i'm loading is: <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false&amp;key=MY_API_KEY" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map_canvas")); var geocoder = new GClientGeocoder(); geocoder.getLatLng("San Francisco, California",function(point) { if (point) { map.setCenter(point, 7); } }); map.setUIToDefault(); } }); </script> <div id="map_canvas"></div> After retrieving this page, I'm setting its contents to a div using the html() method. The map is not showed, while other pages containing scripts, loaded in the same way, are correctly shown. Is this a specific issue about GMaps, that doesn't allow to be loaded via an ajax request? Thanks

  • How to express inter project dependencies in Eclipse PDE

    - by Roland Tepp
    I am looking for the best practice of handling inter project dependencies between mixed project types where some of the projects are eclipse plug-in/OSGI bundle projects (an RCP application) and others are just plain old java projects (web services modules). Few of the eclipse plug-ins have dependencies on Java projects. My problem is that at least as far as I've looked, there is no way of cleanly expressing such a dependency in Eclipse PDE environment. I can have plug-in projects depend on other plug-in projects (via Import-Package or Require-Bundle manifest headers), but not of the plain java projects. I seem to be able to have project declare a dependency on a jar from another project in a workspace, but these jar files do not get picked up by neither export nor launch configuration (although, java code editing sees the libraries just fine). The "Java projects" are used for building services to be deployed on an J2EE container (JBoss 4.2.2 for the moment) and produce in some cases multiple jar's - one for deploying to the JBoss ear and another for use by client code (an RCP application). The way we've "solved" this problem for now is that we have 2 more external tools launcher configurations - one for building all the jar's and another for copying these jar's to the plug-in projects. This works (sort of), but the "whole build" and "copy jars" targets incur quite a large build step, bypassing the whole eclipse incremental build feature and by copying the jars instead of just referencing the projects I am decoupling the dependency information and requesting quite a massive workspace refresh that eats up the development time like it was candy. What I would like to have is a much more "natural" workspace setup that would manage dependencies between projects and request incremental rebuilds only as they are needed, be able to use client code from service libraries in an RCP application plug-ins and be able to launch the RCP application with all the necessary classes where they are needed. So can I have my cake and eat it too ;) NOTE To be clear, this is not so much about dependency management and module management at the moment as it is about Eclipse PDE configuration. I am well aware of products like [Maven], [Ivy] and [Buckminster] and they solve a quite different problem (once I've solved the workspace configuration issue, these products can actually come in handy for materializing the workspace and building the product)

  • How to Select Items in Dropdown in Selenium

    - by Marcus Gladir
    Firstly, I have been trying to get the dropdown from this web page: http://solutions.3m.com/wps/portal/3M/en_US/Interconnect/Home/Products/ProductCatalog/Catalog/?PC_Z7_RJH9U5230O73D0ISNF9B3C3SI1000000_nid=RFCNF5FK7WitWK7G49LP38glNZJXPCDXLDbl This is the code I have: import urllib2 from bs4 import BeautifulSoup import re from pprint import pprint import sys from selenium import common from selenium import webdriver import selenium.webdriver.support.ui as ui from boto.s3.key import Key import requests url = 'http://solutions.3m.com/wps/portal/3M/en_US/Interconnect/Home/Products/ProductCatalog/Catalog/?PC_Z7_RJH9U5230O73D0ISNF9B3C3SI1000000_nid=RFCNF5FK7WitWK7G49LP38glNZJXPCDXLDbl' element_xpath = '//*[@id="Component1"]' driver = webdriver.PhantomJS() driver.get(url) element = driver.find_element_by_xpath(element_xpath) element_xpath = '/option[@value="02"]' all_options = element.find_elements_by_tag_name("option") for option in all_options: print("Value is: %s" % option.get_attribute("value")) option.click() source = driver.page_source.encode('utf-8', 'ignore') driver.quit() source = str(source) soup = BeautifulSoup(source, 'html.parser') print soup What prints out is this: Traceback (most recent call last): File "../../../../test.py", line 58, in <module> Value is: XX main() File "../../../../test.py", line 46, in main option.click() File "/home/eric/dev/octocrawler-env/local/lib/python2.7/site-packages/selenium-2.33.0-py2.7.egg/selenium/webdriver/remote/webelement.py", line 54, in click self._execute(Command.CLICK_ELEMENT) File "/home/eric/dev/octocrawler-env/local/lib/python2.7/site-packages/selenium-2.33.0-py2.7.egg/selenium/webdriver/remote/webelement.py", line 228, in _execute return self._parent.execute(command, params) File "/home/eric/dev/octocrawler-env/local/lib/python2.7/site-packages/selenium-2.33.0-py2.7.egg/selenium/webdriver/remote/webdriver.py", line 165, in execute self.error_handler.check_response(response) File "/home/eric/dev/octocrawler-env/local/lib/python2.7/site-packages/selenium-2.33.0-py2.7.egg/selenium/webdriver/remote/errorhandler.py", line 158, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.ElementNotVisibleException: Message: u'{"errorMessage":"Element is not currently visible and may not be manipulated","request":{"headers":{"Accept":"application/json","Accept-Encoding":"identity","Connection":"close","Content-Length":"81","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:51413","User-Agent":"Python-urllib/2.7"},"httpVersion":"1.1","method":"POST","post":"{\\"sessionId\\": \\"30e4fd50-f0e4-11e3-8685-6983e831d856\\", \\"id\\": \\":wdc:1402434863875\\"}","url":"/click","urlParsed":{"anchor":"","query":"","file":"click","directory":"/","path":"/click","relative":"/click","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/click","queryKey":{},"chunks":["click"]},"urlOriginal":"/session/30e4fd50-f0e4-11e3-8685-6983e831d856/element/%3Awdc%3A1402434863875/click"}}' ; Screenshot: available via screen And the weirdest most infuriating bit of it all is that sometimes it actually all works out. I have no clue what's going on here.

  • Spring MVC parameter validation

    - by Don
    Hi, I've defined a controller, validator and command class for a Spring 2.5 MVC application like this: public class ResourceController extends AbstractCommandController { private MessageRetriever messageRetriever; protected ModelAndView handle(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception { ResourceCommand resourceCommand = (ResourceCommand) command; // I NEED TO CHECK HERE IF COMMAND IS VALID? } public static class ResourceCommand { private String module; private String site; private String lang; // GETTERS AND SETTERS OMITTED } public static class ResourceValidator implements Validator { public boolean supports(Class clazz) { return ResourceCommand.class.isAssignableFrom(clazz); } public void validate(Object obj, Errors errors) { ValidationUtils.rejectIfEmptyOrWhitespace(errors, "module", "MODULE_REQUIRED"); ValidationUtils.rejectIfEmptyOrWhitespace(errors, "site", "SITE_REQUIRED"); ValidationUtils.rejectIfEmptyOrWhitespace(errors, "lang", "LANG_REQUIRED"); } } } I have wired these all together in the application context: <bean id="resourceController" class="com.amadeus.jcp.ui.framework.localization.ResourceController"> <property name="commandClass" value="com.amadeus.jcp.ui.framework.localization.ResourceController.ResourceCommand"/> <property name="validator"> <bean class="com.amadeus.jcp.ui.framework.localization.ResourceController.ResourceValidator"/> </property> </bean> However, I can't figure out how to actually check whether the command is valid or not - I assume the framework calls the validator, but how do I get access to the result? Incidentally, I'm using Java 1.4, so can't use any solutions that require annotations or other Java 1.5 features. Thanks, Don

  • REST API Best practice: How to accept as input a list of parameter values

    - by whatupwilly
    Hi All, We are launching a new REST API and I wanted some community input on best practices around how we should have input parameters formatted: Right now, our API is very JSON-centric (only returns JSON). The debate of whether we want/need to return XML is a separate issue. As our API output is JSON centric, we have been going down a path where our inputs are a bit JSON centric and I've been thinking that may be convenient for some but weird in general. For example, to get a few product details where multiple products can be pulled at once we currently have: http://our.api.com/Product?id=["101404","7267261"] Should we simplify this as: http://our.api.com/Product?id=101404,7267261 Or is having JSON input handy? More of a pain? We may want to accept both styles but does that flexibility actually cause more confusion and head aches (maintainability, documentation, etc.)? A more complex case is when we want to offer more complex inputs. For example, if we want to allow multiple filters on search: http://our.api.com/Search?term=pumas&filters={"productType":["Clothing","Bags"],"color":["Black","Red"]} We don't necessarily want to put the filter types (e.g. productType and color) as request names like this: http://our.api.com/Search?term=pumas&productType=["Clothing","Bags"]&color=["Black","Red"] Because we wanted to group all filter input together. In the end, does this really matter? It may be likely that there are so many JSON utils out there that the input type just doesn't matter that much. I know our javascript clients making AJAX calls to the API may appreciate the JSON inputs to make their life easier. Thanks, Will

  • How to set up RPX widget and facebook app to be able to authenticate with rpx_now?

    - by Andrei
    Using the sample app for rpx_now gem ( http://github.com/grosser/rpx_now_example) on localhost:3000, I have successfully logged in via Google Accounts, myOpenID, Yahoo, but cannot make it via Facebook. In the RPX app/widget settings I have set my facebook-app key and secret. In my facebook app settings, the Connect URL is myappname.rpxnow.com. But when I try to connect, then I don't even see a facebook login page, just a number of redirects and I am back to my localhost with the following exception http://gist.github.com/386520 . Before I was successfully connecting with oauth2 gem, however, without fetching user data - only authentication. That time I set only key/secret and localhost as my Connect URL. Currently, I don't even ask for email etc., but still the same problem. Can it happen because rpx_now cannot get requested user data from facebook? Or it is a problem of facebook key/secret? May be I need to provide more settings of my facebook app? RPXNow::ApiError in UsersController#create Got error: Invalid parameter: token (code: 1), HTTP status: 200 RAILS_ROOT: /home/Andrei/rpx_now_example Application Trace | Framework Trace | Full Trace /usr/lib/ruby/gems/1.8/gems/rpx_now-0.6.20/lib/rpx_now/api.rb:71:in `parse_response' /usr/lib/ruby/gems/1.8/gems/rpx_now-0.6.20/lib/rpx_now/api.rb:21:in `call' /usr/lib/ruby/gems/1.8/gems/rpx_now-0.6.20/lib/rpx_now.rb:23:in `user_data' /home/Andrei/rpx_now_example/app/controllers/users_controller.rb:16:in `create' Request Parameters: None Show session dump Response Headers: {"Content-Type"="", "Cache-Control"="no-cache"}

  • Apache RewriteRule: it is possible to 'detect' the first and second parameter?

    - by DaNieL
    Im really really a newbie in regexp and i cant figure out how to do that. My goal is to have the RewriteRule to 'slice' the request url in 3 parts: example.com/foo #should return: index.php?a=foo&b=&c= example.com/foo/bar #should return: index.php?a=foo&b=bar&c= example.com/foo/bar/baz #should return: index.php?a=foo&b=bar&c=baz example.com/foo/bar/baz/bee #should return: index.php?a=foo&b=bar&c=baz/bee example.com/foo/bar/baz/bee/apple #should return: index.php?a=foo&b=bar&c=baz/bee/apple example.com/foo/bar/baz/bee/apple/and/whatever/else/no/limit/in/those/extra/parameters #should return: index.php?a=foo&b=bar&c=baz/bee/apple/and/whatever/else/no/limit/in/those/extra/parameters In short, the first parameter in the url (foo) should be given to a, the second (bar) to b, and the rest of the string in c I wroted this one <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !=/favicon.ico RewriteRule ^(([a-z0-9/]))?(([a-z0-9/]+))?(([a-z0-9]+))(.*)$ index.php?a=$1&b=$2&c=$3 [L,QSA] </IfModule> but obviously doesnt work, and i dont even know if what i want is possible. Any suggestion?
