[news.eclipse.platform.swt] Force Shell Focus

[cboujennah@xxxxxxxxx (Chris. B.)]

Hi, everybody!
I'm working on an application which can be called by other apps. When it 
is the case, my Eclipse application should take the focus and appear on 
top of the other windows. I'm working under Windows XP SP2.
I've tried this:
==================
PlatformUI.getWorkbench().getDisplay().asyncExec(new Runnable() {
     public void run() {
       IWorkbench workbench = PlatformUI.getWorkbench();
       IWorkbenchWindow activeWorkbenchWindow = 
workbench.getActiveWorkbenchWindow();
       Shell shell = activeWorkbenchWindow.getShell();
       shell.forceActive();
     }
   });
==================
But the taskbar only flashes and tells me that something happened in my 
application. It does not come back in front of windows.
Does anyone have any idea???
Thanks in advance!
