Use Jboss3.0.4-tomcat4.1.12,
When call the stateless EJB on the other Jboss Serverwith the same version from a transactional context,
I gets following exception message:

18:58:42,782 INFO [STDOUT] error marshalling arguments; nested exception is:

It is okay when call the EJBs in other Jboss server
from a non-transactional context.
Doesn't Jboss support transaction propagation now?
How can I call the EJBs on other Jboss server in
a transactional env?
