• Blackberry MDS simulator - Can't connect to the internet in the simulator.

  - by bcoyour

  I'm trying to do some testing of a website through the Blackberry simulator, while the simulator works fine, I can't get to any sites in the Blackberry Browser. Here is the specific setup I'm using. I'm Windows 7 (64-bit) Home Edition I have the latest (at the time) MDS installation - BlackBerry Email and MDS Services Simulators 4.1.4 Finally, I have the latest (at the time) Blackberry Simulator - BlackBerry Smartphone Simulators 5.0.0 (5.0.0.442) - 9700 I first start the MDS service, it briefly pops up the command-prompt and then closes it. I'm assuming that when it does that, it started the MDS service. Then I open the Blackberry simulator (9700), which opens up fine and loads the Blackberry OS. Then with the Blackberry OS all loaded up, I navigate to the browser and for example type www.google.com and then at the bottom it just says "sending request" and loads for about a minute. Then times out and says it can't find a connection. Anyone have any thoughts on what I'm missing? Or, does anyone know of an online simulator for the Blackberry, because thus far this has been a huge pain for testing sites on a Blackberry. Thank you! Ben

• WCF 3.5 - Remove SVC Extension - Special Case

  - by Brandon

  I have several RESTful endpoints like such: System.Security.Role.svc System.Security.User.svc etc. This is meant to be a namespace so our RESTful URL's would look like: /rest/{class namespace}/{actions} I have tried a few examples to get the SVC extension removed when my endpoint has multiple periods in it, however, nothing seems to work. I have tested with the WCF REST Contrib package (http://wcfrestcontrib.codeplex.com/), this example (http://www.west-wind.com/weblog/posts/570695.aspx), and another StackOverflow post (http://stackoverflow.com/questions/355165/how-to-remove-thie-svc-extension-in-restful-wcf-service). This works great when my endpoint is something like this: Echo.svc It will properly remove the SVC extension. Any ideas on how to handle endpoints with multiple periods in the endpoint name? EDIT: After some further testing, I found out that it is failing because whenever you do: string path = HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath; If the endpoint contains multiple periods, it strips off everything after the endpoint causing all of the standard IHttpModule's to fail. Example: If I call http://localhost/services/Echo/test, my relative app file path has a returned value of: ~/echo/test However, if I make a call as http://localhost/services/System.Security.User/test, then my relative app file path has a returned value of: ~/system.security.user I am missing the '/test' on the end in that situation.

• How can I make an AJAX link work once it is moved out of the iFrame?

  - by KcYxA

  Hi, I am using an iFrame with a form that return some content with an AJAX link. I am then moving the returned content out of the iFrame into the main page. However, then the ajax link does not work and the error "Element is null" is created once the link is clicked. How can I move content from the iFrame and still have the AJAX link working? Here's the code returned by the iFrame: <span id="top"> <a id="link8" onclick=" event.returnValue = false; return false;" href="/item_pictures/delete/7"> <img src="/img/delete.bmp"/> </a> <script type="text/javascript"> parent.Event.observe('link8', 'click', function(event) { new Ajax.Updater('top','/item_pictures/delete/3', { asynchronous:true, evalScripts:true, onCreate:function(request, xhr) { document.getElementById("top").innerHTML = "<img src=\"/img/spinner_small.gif\">"; }, requestHeaders:['X-Update', 'top'] }) }, false); </script> </span>

• IoC and dataContext disposing in asp.net mvc 2 application

  - by zerkms

  I have the Global.asax like the code below: public class MvcApplication : System.Web.HttpApplication { public static void RegisterRoutes(RouteCollection routes) { // .... } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); ControllerBuilder.Current.SetControllerFactory(typeof(IOCControllerFactory)); } } public class IOCControllerFactory : DefaultControllerFactory { private readonly IKernel kernel; public IOCControllerFactory() { kernel = new StandardKernel(new NanocrmContainer()); } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { if (controllerType == null) return base.GetControllerInstance(requestContext, controllerType); var controller = kernel.TryGet(controllerType) as IController; if (controller == null) return base.GetControllerInstance(requestContext, controllerType); var standartController = controller as Controller; if (standartController is IIoCController) ((IIoCController)standartController).SetIoc(kernel); return standartController; } class NanocrmContainer : Ninject.Modules.NinjectModule { public override void Load() { // ... Bind<DomainModel.Entities.db>().ToSelf().InRequestScope().WithConstructorArgument("connection", "Data Source=lims;Initial Catalog=nanocrm;Persist Security Info=True;User ID=***;Password=***"); } } } In this case if somewhere it is the class, defined like: public class UserRepository : IUserRepository { private db dataContext; private IUserGroupRepository userGroupRepository; public UserRepository(db dataContext, IUserGroupRepository userGroupRepository) { this.dataContext = dataContext; this.userGroupRepository = userGroupRepository; } } then the dataContext instance is created (if no one was created in this request scope) by Ninject. So the trouble now is - where to invoke dataContext method .Dispose()?

• Best way to manipulate and compare strings

  - by vtortola

  I'm developing a REST service, so a request could be something like this: /Data/Main/Table=Customers/ I need to get the segments one by one, and for each segment I will decide wich object I'm going to use, after I'll pass to that object the rest of the query so it can decide what to do next. Basically, the REST query is a path on a tree :P This imply lots String operations (depending on the query complexity), but StringBuilder is useful just for concatenations and remove, you cannot perform a search with IndexOf or similar. I've developed this class that fulfill my requirement, but the problem is that is manipulating Strings, so every time I get one segment ... I'll create extra Strings because String is an inmutable data type: public class RESTQueryParser { String _query; public RESTQueryParser(String query) { _query = query; } public String GetNext() { String result = String.Empty; Int32 startPosition = _query.StartsWith("/", StringComparison.InvariantCultureIgnoreCase) ? 1 : 0; Int32 i = _query.IndexOf("/", startPosition, StringComparison.InvariantCultureIgnoreCase) - 1; if (!String.IsNullOrEmpty(_query)) { if (i < 0) { result = _query.Substring(startPosition, _query.Length - 1); _query = String.Empty; } else { result = _query.Substring(startPosition, i); _query = _query.Remove(0, i + 1); } } return result; } } The server should support a lot of calls, and the queries could be huge, so this is gonna be a very repetitive task. I don't really know how big is the impact on the memory and the performance, I've just readed about it in some books. Should I implement a class that manage a Char[] instead Strings and implement the methods that I want? Or should be ok with this one? Regular expressions maybe?

• Silverlight, WCF service, integrated security AND ssl/https not possible?

  - by Flores

  I have this setup that works perfectly when using http. A silverlight 3 client .net 4 WCF service hosted in IIS with basicHttpBinding and using integrated security on the site When setting https to required on the website the setup stops working. Using the wcftestclient on the uri I get the message: The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'. The remote server returned an error: (401) Unauthorized. Maybe this makes sense because the wcftestclient does not pass credentials? in the web.config the security mode for the service binding is set is set to 'Transport'. The silverlight client is created like this: BasicHttpBinding basicHttpBinding = new BasicHttpBinding(); basicHttpBinding.Security.Mode = BasicHttpSecurityMode.Transport; var serviceClient = new ImportServiceClient(basicHttpBinding, serviceAddress); The service address is ofcourse starting with https:// And the silverlight client reports this error: The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via Remember, swithing it back to http (and setting security mode to 'TransportCredentialOnly' makes everything working again. Is the setup I want even supported? If so, how should it be configured?

• Intercepting method with Spring AOP using only annotations

  - by fish

  In my Spring context file I have something like this: <bean id="userCheck" class="a.b.c.UserExistsCheck"/> <aop:config> <aop:aspect ref="userCheck"> <aop:pointcut id="checkUser" expression="execution(* a.b.c.d.*.*(..)) &amp;&amp; args(a.b.c.d.RequestObject)"/> <aop:around pointcut-ref="checkUser" method="checkUser"/> </aop:aspect> </aop:config> a.b.c.UserExistsCheck looks like this: @Aspect public class UserExistsCheck { @Autowired private UserInformation userInformation; public Object checkUser(ProceedingJoinPoint pjp) throws Throwable { int userId = ... //get it from the RequestObject passed as a parameter if (userExists(userId)) { return pjp.proceed(); } else { return new ResponseObject("Invalid user); } } And the class that is being intercepted with this stuff looks like this: public class Klazz { public ResponseObject doSomething(RequestObject request) {...} } This works. UserExistCheck is executed as desired before the call is passed to Klazz. The problem is that this is the only way I got it working. To get this working by using annotations instead of the context file seems to be just too much for my small brain. So... how exactly should I annotate the methods in UserExistsCheck and Klazz? And do I still need something else too? Another class? Still something in the context file?

• IE9 selectAllChildren on an out-of-view element

  - by MrSlayer

  I am trying to replicate a service that is provided by Tynt.com that appends some text to a user's selection when copying. I understand that users don't particularly like this, but it is a client's request to append the URL and copyright notice whenever a user copies something from their website. In current browsers, I am able to do this by creating a DOM element, adding the selected text, appending the copyright text and then selecting the new node: var newSelection = document.createElement( 'div' ); newSelection.style.cssText = "height: 1px; width: 1px; overflow: hidden;"; if( window.getSelection ) { var selection = window.getSelection( ); if( selection.getRangeAt ) { var range = selection.getRangeAt( 0 ); newSelection.appendChild( range.cloneContents( ) ); appendCopyright( ); document.body.appendChild( newSelection ); selection.selectAllChildren( newSelection ); // ... remove element, return selection } } In IE9, this errors out on the selection.selectAllChildren( newSelection ) statement and I was able to figure out that this is because newSelection was effectively "hidden" from the viewport due to the styles applied in the second line above. Commenting that out works, but obviously the new node is shown to the end user. It appears that this was resolved in later versions of IE, but I am having trouble coming up with a workaround that is sufficient for IE9, a browser that I need to support. I've tried a variety of alternatives, like setting visibility: hidden;, positioning it off-screen, and trying some alternative selection functions, but they each present different problems. The error thrown by IE is: SCRIPT16389: Unspecified error.

• Preventing iframe caching in browser

  - by Zarjay

  How do you prevent Firefox and Safari from caching iframe content? I have a simple webpage with an iframe to a page on a different site. Both the outer page and the inner page have HTTP response headers to prevent caching. When I click the "back" button in the browser, the outer page works properly, but no matter what, the browser always retrieves a cache of the iframed page. IE works just fine, but Firefox and Safari are giving me trouble. My webpage looks something like this: <html> <head><!-- stuff --></head> <body> <!-- stuff --> <iframe src="webpage2.html?var=xxx" /> <!-- stuff --> </body> </html> The var variable always changes. Despite the fact that the URL of the iframe has changed (and thus, the browser should be making a new request to that page), the browser just fetches the cached content. I've examined the HTTP requests and responses going back and forth, and I noticed that even if the outer page contains <iframe src="webpage2.html?var=222" />, the browser will still fetch webpage2.html?var=111. Here's what I've tried so far: Changing iframe URL with random var value Adding Expires, Cache-Control, and Pragma headers to outer webpage Adding Expires, Cache-Control, and Pragma headers to inner webpage I'm unable to do any JavaScript tricks because I'm blocked by the same-origin policy. I'm running out of ideas. Does anyone know how to stop the browser from caching the iframed content?

• Exception during secure communication implementation

  - by Liran

  hi everyone. im trying to implement simple secured client server communiction using WCF. when im launching mt server everty thing is OK , But when im launching my client im getting this error: Error : An error occurred while making the HTTP request to https://localhost:800 0/ExchangeService. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caus ed by a mismatch of the security binding between the client and the server. this is the server code : Uri address = new Uri("https://localhost:8000/ExchangeService"); WSHttpBinding binding = new WSHttpBinding(); //Set Binding Params binding.Security.Mode = SecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None; binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None; Type contract = typeof(ExchangeService.ServiceContract.ITradeService); ServiceHost host = new ServiceHost(typeof(TradeService)); host.AddServiceEndpoint(contract, binding, address); host.Open(); this is the client configuration (app.config): </client> <bindings> <wsHttpBinding> <binding name="TradeWsHttpBinding"> <security mode="Transport"> <transport clientCredentialType="None" proxyCredentialType ="None"/> </security> </binding> </wsHttpBinding> </bindings> the security configuration at both the client and the server are the same , and i dont need certificate for the server in that kind of security (transport) so why do i get this exception ???? thanks...

• Post a form from asp to asp.Net

  - by Atomiton

  I have a classic asp application. I want to post a contest form from that page to an Asp.Net form. The reason is that I want to use a lot of logic i have built into an Asp.Net page for validation before entering into the database and I don't know asp very well. Not to mention asp.Net being more secure. What's the best way to accomplish this goal? My thoughts are as follows: My asp Page: <html> <body> <form action="/Contests/entry.aspx" method="post"> Name: <input type="text" name="fname" size="20" /> Last Name: <input type="text" name="lname" size="20" /> <input type="submit" value="Submit" /> </form> </body> </html> aspx page is running in a Virtual Directory and would handle anything posted to it. Is this possible, or does aspx prevent this kind of thing? I ( preferably ) don't want to create the form in aspx as my colleague wants to have control of the page and build the html himself and I don't want the hassle of constantly changing it. Are there caveats I need to consider? What roadblocks will I run into? How do I access the Posted Form Values? Request.Form?

• Overlay an HTML page with an HTML form

  - by jah

  Hi folks, this is a question about the best way (or least effort of the best ways) to overlay an html page with a form. Best in this context meaning best user experience whilst meeting the functional requirements. Let's say I have a page with a short form on it; the user has to enter some financial details. To assist the user to enter an accurate value for one of the fields there's another, much longer form. The longer form needs to be displayed only if the user requests the help. For users without javascript, clicking a link will submit the short form (persisting already filled fields in a session) and the server will respond with the long form. They'll submit the long form and the server will combine the submitted data with the persisted data and serve the short form again - with the fields populated. For users with javascript I want to overlay the short form page (in a lightbox stylee) with the long form, allow them to populate the long form and then go back to the short form with less round-trips to the server. Do I: Overlay the short form page with an iframe whose target is the long form? Request the long form over ajax and stuff it into a div? Generate the long form entirely on the client-side? Some other wizadry I haven't thought of? A short explanation of the best mechanism will do me very nicely indeed. Thank you very much!

• Having trouble with extension methods for byte arrays

  - by Dave

  I'm working with a device that sends back an image, and when I request an image, there is some undocumented information that comes before the image data. I was only able to realize this by looking through the binary data and identifying the image header information inside. I've been able to make everything work fine by writing a method that takes a byte[] and returns another byte[] with all of this preamble "stuff" removed. However, what I really want is an extension method so I can write image_buffer.RemoveUpToByteArray(new byte[] { 0x42, 0x4D }); instead of byte[] new_buffer = RemoveUpToByteArray( image_buffer, new byte[] { 0x42, 0x4D }); I first tried to write it like everywhere else I've seen online: public static class MyExtensionMethods { public static void RemoveUpToByteArray(this byte[] buffer, byte[] header) { ... } } but then I get an error complaining that there isn't an extension method where the first parameter is a System.Array. Weird, everyone else seems to do it this way, but okay: public static class MyExtensionMethods { public static void RemoveUpToByteArray(this Array buffer, byte[] header) { ... } } Great, that takes now, but still doesn't compile. It doesn't compile because Array is an abstract class and my existing code that gets called after calling RemoveUpToByteArray used to work on byte arrays. I could rewrite my subsequent code to work with Array, but I am curious -- what am I doing wrong that prevents me from just using byte[] as the first parameter in my extension method?

• Cocoa Read NSInputStream from FTP connection

  Hi, I (apparently) manage to make a ftp connection, but fail to read anything from it, and with good cause: I don't reach the reading until the connection has timed out.

Any help is greatly appreciated as I find Xcode quite horrible for debugging (no exception or error msg on failed steps what so ever). Chuck

• ASP.NET MVC - Entending the Authorize Attribute

  - by Mad Halfling

  Hi folks, currently I use [Authorize(Roles = ".....")] to secure my controller actions on my ASP.NET MVC 1 app, and this works fine. However, certain search views need to have buttons that route to these actions that need to be enabled/disabled based on the record selected on the search list, and also the security privs of the user logged in. Therefore I think I need to have a class accessing a DB table which cross-references these target controller/actions with application roles to determine the state of these buttons. This will, obviously, make things messy as privs will need to be maintained in 2 places - in that class/DB table and also on the controller actions (plus, if I want to change the access to the action I will have to change the code and compile rather than just change a DB table entry). Ideally I would like to extend the [Authorize] functionality so that instead of having to specify the roles in the [Authorize] code, it will query the security class based on the user, controller and action and that will then return a boolean allowing or denying access. Are there any good articles on this - I can't imagine it's an unusual thing to want to do, but I seem to be struggling to find anything on how to do it (could be Monday-morning brain). I've started some code doing this, looking at article http://schotime.net/blog/index.php/2009/02/17/custom-authorization-with-aspnet-mvc/ , and it seems to be starting off ok but I can't find the "correct" way to get the calling controller and action values from the httpContext - I could possibly fudge a bit of code to extract them from the request url, but that doesn't seem right to me and I'd rather do it properly. Cheers MH

• Detection of page refresh / F5 key in ASP.NET MVC 2

  - by Michael

  How would one go about detecting a page refresh / F5 key push on the controller handling the postback? I need to distinguish between the user pressing one of two buttons (e.g., Next, Previous) and when the F5 / page refresh occurs. My scenario is a single wizard page that has different content shown between each invocation of the user pressing the "Next" or "Previous" buttons. The error that I am running into is when the user refreshes the page / presses the F5 key, the browser re-sends the request back to the controller, which is handled as a post-back and the FormCollection type is used to look for the "submitButton" key and obtain its value (e.g., "Next," "Send"). This part was modeled after the post by Dylan Beattie at http://stackoverflow.com/questions/442704/how-do-you-handle-multiple-submit-buttons-in-asp-net-mvc-framework. Maybe I'm trying to bend MVC 2 to where it isn't meant to go but I'd like to stay with the current design in that the underlying database drives the content and order of what is shown. This allows us to add new content into the database without modifying the code the displays the content. Thanks, Michael

• wsdl return an array of complex types

  - by Anand

  hi, I have defined a web service that will return the data from my mysql data base. I have written the web service in php. Now I have defined a complex type as follows: $server->wsdl->addComplexType( 'Category', 'complexType', 'struct', 'all', '', array( 'category_parent_id' => array('name' => 'category_parent_id', 'type' => 'xsd:int'), 'category_child_id' => array('name' => 'category_child_id', 'type' => 'xsd:int'), 'category_list' => array('name' => 'category_list', 'type' => 'xsd:int') ) ); The above complex type is a row in a table in my database. Now my function must send an array of these rows so how do I achieve the same My code is as follows: require_once('./nusoap/nusoap.php'); $server = new soap_server; $server-configureWSDL('productwsdl', 'urn:productwsdl'); // Register the data structures used by the service $server-wsdl-addComplexType( 'Category', 'complexType', 'struct', 'all', '', array( 'category_parent_id' = array('name' = 'category_parent_id', 'type' = 'xsd:int'), 'category_child_id' = array('name' = 'category_child_id', 'type' = 'xsd:int'), 'category_list' = array('name' = 'category_list', 'type' = 'xsd:int') ) ); $server-register('getaproduct', // method name array(), // input parameters //array('return' = array('result' = 'tns:Category')), // output parameters array('return' = 'tns:Category'), // output parameters 'urn:productwsdl', // namespace 'urn:productwsdl#getaproduct', // soapaction 'rpc', // style 'encoded', // use 'Get the product categories' // documentation ); function getaproduct() { $conn = mysql_connect('localhost','root',''); mysql_select_db('sssl', $conn); $sql = "SELECT * FROM jos_vm_category_xref"; $q = mysql_query($sql); while($r = mysql_fetch_array($q)) { $items[] = array('category_parent_id'=$r['category_parent_id'], 'category_child_id'=$r['category_child_id'], 'category_list'=$r['category_list']); } return $items; } // Use the request to (try to) invoke the service $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server-service($HTTP_RAW_POST_DATA);

• Using PHP cURL with an HTTP Debugging Proxy

  - by Kane

  I'm using the app "Fiddler" to debug a GET attempt to a website via PHP cURL. In order to see the cURL traffic I had to specify that the cURL connection use the Fiddler proxy (see code below). $ch = curl_init(); curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1); curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888'); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_USERAGENT, $user_agent); curl_setopt($ch, CURLOPT_REFERER, "http://domain.com"); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_COOKIEJAR, "my_cookies.txt"); curl_setopt($ch, CURLOPT_COOKIEFILE, "my_cookies.txt"); curl_setopt($ch, CURLOPT_URL, "http://domain.com"); $response = curl_exec($ch); But the problem is that in Fiddler I can only see this: Request (domain.com is just an alias): CONNECT domain.com:80 HTTP/1.1 Response: HTTP/1.1 200 Blind-Connection Established If I manually load the website in a browser Fiddler gives me WAY more information. I can see the cookies, the header information, and what I'm receiving via the GET. Any ideas why Fiddler can't see more useful information from PHP cURL? Edit: I tried turning on the "Enable HTTPS Decryption" option inside Tools / Fiddler Options / HTTPS (which I'm not sure why I'd need to use as I didn't tell cURL to use HTTPS). Unfortunately, by changing this setting I now get a Response of: HTTP/1.1 502 Connection failed Edit: If it helps, the app "Charles" shows me WAY more information than Fiddler, but I really want to figure out Fiddler since I like it better.

• Pentaho - Reporting Tool - Is the .prpt file (report template file) contains datasource information

  - by Yatendra Goel

  I am new Pentaho Reporting Tool. I have the following question: When I created a report using Pentaho Report Designer, it output a report file having .prpt extension. After that I found an example on internet where the following code were used to display the report in html format:| protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ResourceManager manager = new ResourceManager(); manager.registerDefaults(); String reportPath = "file:" + this.getServletContext().getRealPath("sampleReport.prpt"); try { Resource res = manager.createDirectly(new URL(reportPath), MasterReport.class); MasterReport report = (MasterReport) res.getResource(); HtmlReportUtil.createStreamHTML(report, response.getOutputStream()); } catch (Exception e) { e.printStackTrace(); } } And the report got printed successfully. So as we haven't specified any datasource information here, I think that the .prpt file contains that information in it. If that's true than Isn't Jasper is better Reporting tool than Pentaho because when we display Jasper reports, we have to provide datasource details also so in that way our report is flexible and is not bound to any particular database.

• Wysiwyg with image copy/paste

  - by jW

  First, I understand that an image cannot be "copied" from a local machine into a website. I understand that it must be uploaded. I am a web programmer, and am familiar with common web wysiwyg tools such as TinyMCE and FCKEditor. My question is if there exists a program or web module or something of the sort that works will perform an automatic upload of images for a wysiwyg. I have a client that is constantly complaining about not being able to copy/paste documents with images from MS Word into a wysiwyg to create content on their website. I have looked into TX Text Control (http://labs.textcontrol.com/) and was looking into a possibly flash wysiwyg that could upload the file automatically behind the scenes. I don't know if this exists, and google did not much help me in my search, so I thought I would ask other coders. I am open to any sort of server technology, or browser requirements. I am looking for some browser based tool instead of an application tool such as Dreamweaver or otherwise. If no good solution to the problem exists, I am willing to accept that at this point. Note: This was a request from a client, and to me it seemed rather unreasonable. I decided to gather community advice instead of just tell the client 'No' and the options here have been extremely helpful and informative in presenting possible solutions.

• JSF Render response programmatically

  - by Shamik

  I have one parent page with a parentManagedBean (attached to Session Scope). On click of a button on this parent page, one popup comes which has a childManagedBean (attached to Request scope). Now ChildManagedBean holds a reference to parentManaged bean through JSF's managed property facility. On this popup window, user selects some option which populates a large value object. I use the managed property of childManagedBean to set the values from this large object to that of parentManagedBean. Problem is - The parent page shows a link, on click of which a popup comes, on selection of the popup, the popup disappears and set the values to the parentManaged bean. So far so good, but the newly set values need to appear on the parent page. This is where I am stuck. How to programmatically render the master page/render page when I am at the child managed bean? Is there a way I can get handle of the parent page and refresh it? Note: I'm using JSF 1.1 EDIT- After following the solution of "resubmit-ing the form" from javascript, I am seeing that the old form is getting resubmitting which overwrites all of my changed values.

• Implementing Struts 2 Interceptors using Struts 1

  - by Andriy Zakharchuk

  Hello all, I have a legacy application written with Struts 1. The only feature I was asked to add is to protect some actions. Currently any user can do whatever he/she wants. The idea is to allows all user see the data, but block modification operation, i.e. to modify data a user should log in. I know Struts2 has interceptors, so I could attach them to required actions and forward users to log in page when needed. But how can I do similar thing in Struts 1 application? My first idea was to create my own abstract Action class: public class AuthenticatedAction { public ActionForward execute( ActionMapping mapping, ActionForm form, HttpServletRequest theRequest, HttpServletResponse theResponse) { if (!logged) { // forward to log in form } else { doExecute(mapping, form, request, response); } } public abstract ActionForward doExecute( ActionMapping mapping, ActionForm form, HttpServletRequest theRequest, HttpServletResponse theResponse); } Then change all actions that require authentication from extends Action to extends AuthenticatedAction then add login form, login action (which performs authentications and puts this status into the session) and change JSP header tile to display authentication block, e.g., "You are (not logged in)/", Login/Logout. As I guess this should solve the problem. If this doesn't solve the problem, please explain me why. Is there any better (more elegant like interceptors are) way to do this? Thank you in advance.
