Carlo explained to me why this no longer works. In essence, the spec says that if you are accessing EJBs from a servlet, then you must declare your EJBs in web.xml (this is true for all other EJB3 implementations). JBoss EJB3/AS4/AS4.2 provided an extension to this, such that EJBs were available in global JNDI, and you didn't have to type them all out in web.xml. This was a (nice) piece of value add that JBoss EJB3 provided, and Seam took advantage of. Carlo, correct me if I'm wrong :) So, taking this forward - without this, there are no Seam examples that are guaranteed to work in AS5. We'll add a jboss5 configuration to the port of booking example to jee5 so that we have at least one example that runs. And I guess we start converting our examples over to be non-EJB3 so that they run on both JBoss 4.2 and 5.
