Hi Tim, I sent the test program to you by e-mail. I would have preferred to stick with Messaging 1.0.1 for the time being as we do not need clustering and have performed all our tests with this release. But as this seems to be a dead end, we have to reconsider. Has stability and performance of 1.2.0 now reached a level comparable to 1.0.1? On another thread (http://www.jboss.com/index.html?module=bb&op=viewtopic&t=105371) I read about problems with 1.2.0 and the ServiceBindingManager. Has this been resolved? We are dependent on this to work, as we have to run several instances in parallel on the same hardware. Many thanks, Ralf Torsten View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4045434#...
