Hi, I removed hsqldb-ds.xml and replaced it with oracle-ds.xml. For this reason, I changed the following files by replacing DefaultDS to OracleDS (your Datasource name). conf/login-config.xml deploy/uuid-key-generator.sar/META-INF/jboss-service.xml deploy/ejb-deployer.xml deploy/jms/hsqldb-jdbc-state-service.xml deploy/jms/hsqldb-jdbc2-service.xml --> replace with oracle-jdbc2-service.xml from $JBOSS_HOME/examples/jms and use your Datasource name braca View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4192960#...
