Hi everybody!

I have a question related to Tomcat / JBoss integration:

I have a very simple J2EE app (from Java Tools from Extreme Programming). A servlet is calling an EJB.

The war file is deployed on Tomcat 4.1.12. The EJB is deployed on JBoss 3.0.3.

Looking at the Communication Exception below, can anyone tell me what is wrong in my configuration and why Tomcat cannot communicate with JBoss?
