Re: [Wicket-user] Upload Progress bar

[Andrew Lombardi]

johan, ok, i've attempted that, and ran into the same blocking-type behaviour.  I've added the following to the init() of my Application:         DynamicByteArrayResource dbar = new DynamicByteArrayResource() {             protected byte[] getData() {                 if(RequestCycle.get()!=null) {                 ProgressSession sess = (ProgressSession) RequestCycle.get().getSession();                 if(sess!=null) {                     int count = sess.getCount();                     String countStatus = "count: "+count;                     return countStatus.getBytes();                 }                 }                 return "".getBytes();             }             public String getContentType() {                 return "text/html";             }         };         Application.get().getSharedResources().add("statusResource", dbar); ProgressSession being a Session implementation holding property count. And then in a Page component, I've grabbed a ResourceReference and printed out the accessor url with this:         ResourceReference ref = new ResourceReference( "statusResource");         String url = "">         System.out.println("url:"+url); And the resource gets pulled up fine without the upload occuring at the same time.  but once the upload occurs, it seems to exhibit a blocking behaviour. any ideas?  it shouldn't behave this way right?  i'm using 1.1 final. -kin On Nov 23, 2005, at 3:02 PM, Johan Compagner wrote: just an idea. The progress bar thread could be a SharedResource request. Those request are not synchonized. And you can give back the progress number everytime the Resource is requested. johan On 11/23/05, Andrew Lombardi <[EMAIL PROTECTED]> wrote: I've got a need to show an Upload progress bar in a Wicket app that I've built.  We're uploading some fairly large files and would like to see some statuses.  Figured out with Igor how to go about injecting a CountingInputStream into the process for FileUpload, but have run into a roadblock! What ends up happening, is the page runs a _javascript_, to show another page that meta refreshes and shows a status grabbed from the session.  And at the same time submits the form to start the upload. Only problem is, it seems to block on the form submission  uploading the file, and never shows the status page until after its done processing the form.  Obviously too late. Igor mentioned that this was probably because Wicket synchronizes with the session.  And we both think there must be a way around this that is missing. the code I have overrides: protected WebRequest newWebRequest(HttpServletRequest servletRequest) and then subclasses ServletWebRequest offering a wrapped MultipartServletWebRequest which passes back a custom FileItem that wraps the InputStream in a CountingInputStream, that in turn updates the Session.  Whew!  That was long.
