[jboss-user] [EJB/JBoss] - ejb deployer violation - Oracle

I am trying to use Oracle for Jboss Portal Server by the following steps. 1. copy and edit portal-oracle-ds.xml into server/defaultdeploy directory. 2. Delete portal-hsqldb-ds.xml 3. startup by run.bat Before I connect to Oracle, the example application RosterApp was deployed correctly and working fine with Oracle. After I have change the Portal database to Oracle, there is error messages popped up during startup. Does anyone help me?
