Re: AMQ 4.0.x & MDB Listener not connecting
Hi James,
I am also facing the same issue with WAS5 and ActiveMQ4.1.1
This appears to be a local transaction issue in websphere.
This happens when websphere tries to create a new server session by calling
new ServerSession() [com.ibm.ejs.jms.listener.ServerSession]. The
constructor starts a local transaction and then goes into an infinite loop.
I have attached the file ServerSession.java
I have also attached the server trace logs.
Please advise.
Regards,
Suraj
