Hi I commented the CachedConnectionValve at end of the server.xml file. Also commented the CachedConnectionManager in META-INF/jboss-service.xml. The "Connection is not associated with a managed connection" is gone and application is running fine. By the way, this warning appears when there are unclosed connections. <track-statements>false</track-statements> in datasource .xml file would help hide warnings if statements are not closed. Hope it helps. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4234685#... Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&a...
