Looks like we will club all the datasource RAR into a single RAR for the upcoming versions of the JBoss. The initial comments of the JIRA indicates that jboss-ha-xa-jdbc.rar and jboss-ha-local-jdbc.jar should be clubbed in the single rar file , is this what we are trying to achieve ? Or we will have all the 5 rar's corresponidng to Datasource in single RAR. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3996562#...
