Why dont you have Servlets generate JSP pahes and then jave jsp pass data
back to a servlet. Alternatively you could have Servlets pass data to an
EJB and use Servlets/EJB.

No. The bean here sits on the Server side and as far as I know it is not
possible to download the Bean onto the client for GUI.  Is this a real GUI
that cannot be created with just advanced HTML tags?  You can write a
servlet that creates Tree Control using basic images.

Applets are not a bad idea, but can really hurt performance of an
application if the client is not on a fast connection.  probably want to
consider that.
