Hello,
Nevertheless, after you you'll have solved all you problems, you'll not be
able to make applet access EJB in the current code status. Due to a bug, the
dynamic classloading does not work (if apps are not on the same host than
the server). The RMI subsystem, when unmarshalling your stub, will get a
file URL codebase (file://c:/jboss/...) relative to your JBoss server. Any
app will try to download class from it, fail (if distant) and try the local.
Applets will try and raise a security exception.
Vladimir Blagojevic and I have been discussed this issue and haven't found a
true clean solution. We have tried to get some support/hints from Rickard
but he seems to have left the JBoss planet for some time. ;)
You may also try to simply sign your applet (what I did).
Cheers,
Sacha
