Felix, I believe this is a Tomcat bug. Tomcat seems unable to locate EJBs unless you put a copy of your application jars and the JBoss client jars in the $TOMCAT_HOME/lib directory as well as your app's directory. At least this is what I found after much digging in various mailing lists. Hope that helps! Frank T.
