Have a look at the JFace ProgressMonitorDialog, it displays the progress
of a long-running operation. You have to wrap your operation in an
IRunnableWithProgress and pass it to the run method of the dialog.

Roland,
you are launching with org.eclipse.rap.ui.workbench but do not
actually start the workbench (PlatformUI#createAndRunWorkbench).
This might cause the NPE.
From looking at the code (while (!container.isDisposed())...), it
seems that you are using RWT standalone. In this case you would need
to provide an IProgressMonitor implementation and/or use one that
comes with JFace.
This article might give you some directions:
