Java EE (Java Enterprise Edition) General Discussion

Hi,

I'm trying to get a stateless EJB to make calls to another stateless EJB running in a different container in a different weblogic server.
I've set up a simple test, where a client calls a method on test EJB 1 in weblogic server 1, which itself makes a call to test EJB 2 in weblogic server 2.
Both EJBs are extremely simple. EJB 1 simply contains one method that prints out some debug, gets the JNDI context of server 2, gets the remote interface of EJB 2 and calls a method on it, which simply prints out some debug.
This simple example works perfectly providing the trans-attribute tag in the ejb-jar.xml deployment descriptor is set to "NotSupported". If I give any transactionl properties to either EJB, I get the below exception.
I need to make these EJBs transactional. How do I set the trans-attribute tags? Can anyone help please?

thanks
