Original exception: com.ibm.ws.exception.WsException: DSRA8101E: DataSource class cannot be used as one-phase: ClassCastException: com.ibm.ws.rsadapter.jdbc.WSJdbcDataSource I can provide the full stack trace if needed. P6Spy, Jakarta Commons DBCP and similar products that will wrap an existing Connection object in it's own connection wrappers will usually surface these kind of exotic issues in managed environments. This is because managed environments will also try to wrap the Connection object so that global transaction/auto-commit handling etc can be enforced by the management container. We were struggling with this in OJB a while ago where combinations of WebLogic/JBoss/Oracle 10 JDBC driver/P6Spy/DBCP had to be dealt with in X number of ways, where X1 and is somewhat annoyingly high... Your specific exception is thrown when WebSphere is trying to wrap the existing Connection object into a ManagedConnection. Unfortunately I can't help you with any WebSpehere-specifics, but as general hints: * try to disable any caching/optimisations on the JDBC level that WebSphere tries to set on the Connection/DataSource * try different auto-commit and transaction settings in WebSpehere and OJB Hope this gives you some leads as to where to start... If you succeed, please report back to the list as we could put this in the FAQ. P6Spy is really useful when debugging OJB problems.
