Recently I had to port a solution consisting of several Seam applications from JBoss AS 4.2.2 to Glassfish v2.1. This had some tricky parts, mainly because Glassfish is strict about J2EE standard, while JBoss AS is quite not.

The exception which needed the most time to figure out was the one below:

The above stack trace is of calling a remote EJB from a Seam integrated Vaadin application. However, a similar exception was thrown if I called the remote EJB method from a single (command line) client. The EJB method is marked as transactional (REQUIRED).

The issue seemed to be related to this: https://jira.jboss.org/browse/JBSEAM-3778 , althought I have no MDBs in the scenario. Upgrading to 2.2.1CR1 solved the problem.
