That seems unusual to me, though I'm not an applet expert as, say,
Andrew is. I have not run across any hybrid applet/JEE applications
before - what advantages does that approach hold?

I can think of myriad disadvantages.

Signing an applet means to provide a trust certificate to the user,
which they have to accept before the applet obtains elevated privileges.
Without that, the applet cannot do things like invoke resources outside
its home domain.

Is the EJB from outside the applet's home domain?

Would a more conventional approach, like having an HTML form submission
trigger servlet actions such as EJB invocation, suit your purposes? It'd
be a lot simpler to engineer.

I don't know the answer to this either. Simple signed applets I can do
but I don't know anything about EJB.
