Remote EJB Lookup Problem
Fun...@hello.net
I am using WebSphere 3.5.5 and IBM's HTTP Server. I use the
following code to do a lookup on a EJB and it works if the code is run
on the same machine as the bean. When I run the code on a different
machine, I get a "Unable to load class: ejb._myBeanHome_Stub" error.
Any ideas?
Code:
env.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.ejs.ns.jndi.CNInitialContextFactory");
env.put(javax.naming.Context.PROVIDER_URL,
"iiop://192.168.1.100:900");
javax.naming.InitialContext context = new
javax.naming.InitialContext(env);
myBeanHome home =
(myBeanHome)PortableRemoteObject.narrow(context.lookup("myBean"),
myBeanHome.class);
Is there any WebShpere configuring I have to do to make "IIOP"
work?
Thanks in advance.

I was having some similar errors to what you describe on 4.0. When I
updated the install to use the Fix Pack 2 for the EJB fixes, the problem was
resolved. You may check to ensure you have all the fixpacks installed for
3.5.
Good luck,
