Loading remote EJB from servlet using jakarta and openejb

Question

I am trying to create an environment where I use
openejb as my EJB container, and JAKARTA Tomcat
as my
Servlet/JSP container. However,
i'm having a problem in lookingup my remote EJB from my
jakarta application.
That exact code works perfectly if I run it standalone. I
am using the same JRE. Jakarta has also loaded the
openejb-0.8.3.jar and openejb_client-0.8.3.jar
What I dont understand is why jakarta
would behave differently than command-line java when I
am
running in the same JRE on a single machine.
Any help would be much appreciated.

Several fairly major improvements have been maid in OpenEJB specifically for the Tomcat people. For one, the whole way you integrate them has completely been rewritten. Now all you have to do is copy a openejb_loader-0.9.1.war into the Tomcat webapps directory and change an init-param in it. Pretty straight forward. OpenEJB 0.8.3 won't work with Tomcat in the same VM, however OpenEJB 0.9.0 and up have been totally revamped in all things related to classloading so that it can co-exist with Tomcats unique classloading architecture.
O'Reilly just published an article detailing the ins and outs of the integration, it's a pretty good read:
