Both hajndi-jms-ds.xml and jms-ds.xml should not have ended up in the deploy directory. There should be only one of them, depending on if you are clustering or not. Because of the install command line you gave: ant -f release-admin.xml -Dmessaging.config.source=all -Dmessaging.config.name=jms the hajndi-jms-ds.xml is the correct file and jms-ds.xml is incorrect (and should be removed). The 'all' configuration includes clustering support. The 'default' configuration contains everything except clustering. You did not by any chance run release-admin.xml twice, once without any options? That would explain the duplication.
