That leads me to another question.
It is my current understanding that Glassfish V2 implements EJB3 and
therefore Message Driven Beans are now controlled by the @MessageDriven
annotation at the bean, not by the sun-ejb-jar.xml.
I haven't been able to find a complete explanation of all possible
properties that can be configured using the @MessageDriven annotation . This
task seems to be closely related to the Application Server. I've tried
looking at Glassfish documentation and also at Sun Application Server 9
documentation. (I did found the mention to the sun-ejb-jar.xml but that was
at Sun Application Server 8 documentation and, as I said, I understand that
is EJB2).
Could you please point me to a good resource for @MessageDriven and/or
sun-ejb-jar.xml.documentation?
Thanks again.
Jorge
