Hi All, I've just tried the same thing on Windows platform only to find that the same issue appears. Then, I tried a "workaround": at Preferences->Servers->Installed Runtime, this time I added a "JBoss 4.2 Runtime" (which is under the tree node of JBoss, a division of Red Hat) (INSTEAD OF what previously I've set "JBoss v5.0" under the JBoss tree node). Oh. It started w/ some errors and warnings but at least it finally reaches as the status of "Started". Does it mean that the only installed Runtime under the tree node of "JBoss, a division of Red Hat" work? Or jboss 5.0 not ready here or anything I mis-configured? For the jboss 5 issue, the last message shown in console before the timeout error is "Binding Transaction Manager JNDI Reference". thanks in advance, jackling View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128267#...
