Hi Mathias,
you can register the required jdk in WebStart. In the german Version under "Datei -> Einstellungen->
Java.
Loading classes under WS works easy.
Step 1: You put them in a jar-File.
"jar -cfv myClasses.jar TestApp.class TestApp$1.class TestApp$2.class ...".
Step 2: You put the jar Files on the Server.
Step 3: Modify the ressourcesTag in your JNLP-File.
But how WebStart works with beans...sorry, I don't know, but let me know:-)
Regards,
Heinz elman
