The only thing that I can see right off is the call to
PortableRemoteObject.narrow(). We use EJBs all the time with JRun. Our
code looks like yours except we never use that call. Try removing it.
Also, you might go into the JMC after you deploy your EJB and verify that
the "ebj.beanHomeName" property for your bean is really "TransactionBean"
like it should be. You should also verify that the ejb.allowedIdentities
property is set to "all" like the properties file says.
The exception you show seems to indicate that the server is having trouble
finding one of the bean classes. I'm not sure why that would be.
If this doesn't solve the problem, let me know and I will look closer.
Take heart! It appears that you are very close.

I have been trying for quite some time to deploy a session bean that will
handle database transactions. I am getting the following error
