Yes, we have simplified clustering considerably in 1.4.0. One of the changes is there are no longer separate clustered and non clustered persistence config files. I recommend you look at the 1.4.0 userguide, since a few other things have changed in clustering too (no more default router policy or message distribution policy). Basically we have tried to make clustering easier to setup and configure. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067595#...
