Hello,
I'm having an INCREDIBLY annoying problem trying to access an EJB that I've
deployed. I'd love it if someone could pitch a hand. Here's the situation
...
Setup:
I'm running JBoss 3 running on JRockit VM.
I'm running Netscape iPlanet-WebServer-Enterprise/4.1SP6 4.1sp6 as the web
server on Sun JVM 1.3.0_02
The Goal:
I've got a jar containing our middle-tier which is linked in by both
Netscape & JBoss. The jar contains 50+ EJBs and their supporting classes.
This application is currently running on a Borland Inprise appserver and
we're attempting to do a port to JBoss.
The Current Status:
The jar is loaded successfully and all EJBs are deployed and verified by
JBoss. All 50+ EJBs are appearing in the Agent View (port 8082). There are
no errors at startup.
The Problem:
However, when we actually attempt to access the EJB (through code proven to
work on WebSphere/Inprise) exceptions are thrown on both the client and
server sides.
The server side claims to have as a missing class the implementation of the
EJB. This class in included in the same jar that contains the home
interface, etc. which it has loaded and registered.
Sample 1 below contains the stack trace from the Server side.
On the client side, we're seeing an InvalidClassException caused by
different versions of a class (which is unknown) between the serialization
and deserialization. I've considered that this could be do to the different
JVMs. I'm not as concerned about this as with the server-side exception.
Sample 2 below contains the stack trace from the Server side.
Any help you can give me is appreciated!
Thanks,
Michael Kenyon
