Simon,
I tried to fetch the Employer enitity bean in the servlet and it works fine.
However, when
i try fetching the entity bean in the session bean it appears that it does
not work.
I tried fixing the deployment descriptor to included the following:

Hey John,
I see that you're using jdk 1.2.2 invokers (and I think you're using jdk
1.2.2); I think that PortableRemoteObject has been moved to core JDK only
with 1.3, so your problem seems that you cannot find the
PortableRemoteObject class. Is this your case ? If so, you'll maybe need to
add javax.rmi package for jdk 1.2.2 to your classpath.
The rollback is a natural consequence of an application exception thrown:
you don't want to commit what you have only partially done before the
exception throw. So the container rollbacks the transaction.
HTH,
Simon
