Question using EJB 2.1 MDB's.

From the EJB 2.1 Spec:
"The EJB 2.0 specification supported only JMS message-driven beans. The EJB 2.1 specification extends the message-driven bean contracts to support other messaging types in addition to JMS[34]. A message-driven bean is defined for a single messaging type, in accordance with the message listener interface it employs."
Does anyone used a MDB with a messaging type other than JMS? Does anyone knows where I can find an example on how I can do that? All the tutorials for J2EE 1.4 use MDB's using JMS. I want to use it with another messaging as the inbound component of a JCA 1.5 RA.
Thanks, for any help

The problem here is that J2EE 1.4 has just recently been finalized and approved. There are no Application Servers that support this technology in anything but a beta/developer preview form. Therefore, nobody is using this stuff for real work so it may be a while before you start seeing more resources. I know that the next edition of Enterprise JavaBeans is currently being finished off by Richard Monson-Haefel and should be released in the next few months... that is probably your best bet.
In the meantime this TSS article that RMH wrote in December 2002.
 
It is sorta covered in the JavaRanch Style Guide.
