DownloadLink and ProgressBar
Hi All,
I have a wicket DownloadLink where I generate file dynamically and download
it. It works.
The process of dynamic File generation might take some time and like to show
ProgressBar which show how much the generation has progressed. How Can I do
that.
I am using wicket 1.5.8
Thank you very much.
add(new DownloadLink(export, new LoadableDetachableModelFile()
{
private static final long serialVersionUID =
840863954694163375L;
@Override
protected File load()
{
File exportTempDir = getGeneratedFile();
}
}

Re: DownloadLink and ProgressBar
Hi,
1-Replace the download link by an AJAX link.
2-Launch file generation on a background thread. Pass a class to this
thread that serves as context fro passing information from generating
thread with web threads (keeping a reference to thisi context on the page).
3-Make a progress panel visible + an AJAX timer that pols the server for
progress.
4-Once file is generated replace progress panel with a download link (or
use trick in [1] to trigger file dowmload)

Re: logout on session destroy
You can write a unboundListener and register it in your sessionStore.
This code should be in your application init()
getSessionStore().registerUnboundListener( new ISessionStore.UnboundListener() {
@Override
public void sessionUnbound(String sessionId) {
// logout timestamp in the database
}
});

Hi all,
it's quite frustrating, a simple thing gets complicated.
I have a Webapp with login page and logout button.
If the user clicks the logout I write a logout timestamp in the database.
Now I want to write the same timestamp when the session expires.
Only thing I have found on the Web is to use
WebApplication.sessionUnbound with Session ID.
When this method is called the AuthenticatedWebSession is still dead I
think or maybe I cant get the Object.
Other thing I found is the method onInvalidate() in the webSession, but
this method is never called. (i'm on Wicket 6.1.)
What is the right way to do the trick??
Thanks in advance

Re: logout on session destroy
Thanks, that works, but how can I get my WebSession Object??
In there the user is stored and I need the id of the user.
WebSession.get() does not work
Thanks in advance

Re: logout on session destroy
Maybe bind sessionId with user ID when session is created? on a persistence
storage? So that you can recover user ID with the session Id

Re: logout on session destroy
In this case, override the onInvalidate() method in your custom session.
from the api :
onInvalidate is a callback method that is executed when the user session is
invalidated
either by explicit call to {@link org.apache.wicket.Session#invalidate()}
or due to HttpSession expiration.

Update to the 6.12 version or follow Ernesto's advice or write your own
HttpSessionStore.

Thanks a lot now it works

Re: DownloadLink and ProgressBar
Thank you Ernesto for your prompt response. 1. is okay. Then for 2. I suppose I start the thread from the onclick method of the ajax link. Can you explain a bit how to start the file genaration with a thread? and for 3. how to pol the server for the progress?
