No, The JMS beta (if you are looking for something JMS-based) has only been out for
about a month. The Point-to-Point and Pub/Sub has been implemented but not the
advanced facilities features. Vendors are struggling to get to EJB 1.1, let alone
adding bells and whistles like messaging integration (yes, I know about WebLogic and
Ejipt).
I don't think you will see true integration of messaging and EJB until EJB 2.0 and the
idea of an asynchronous bean (if it makes it in to 2.0).

You don't need JMS over MQSeries, IBM provides a Java client library. This provides
you the ability to get at MQ functionality not found in JMS. Having said that, yes, I
am using the JMS for MQ package in a framework for my client. The next iteration of
this framework that includes MQ integration goes out in two weeks.
