Armin, Thank you for your response. If I specify JNDI name like jdbc/testdsn in the repository_database.xml, everything works fine. But the problem is, it makes a direct JNDI connection and Websphere is not letting me use the Resource-Ref settings set in the web.xml file. So I tried to use the indirect JNDI by creating a startup class that will bind the datasource alias to the JNDI. For this I followed the weblogic example from the OJB site. I had a create my class that implements serializable in order to bind it to the JNDI. is there any OJB class that I can use to bind the JNDI name in my startup class. Please help. Thanks.

Can any one help? Please.... I assume that that the CCE occur while jndi lookup of the DataSource in method ConnectionFactoryAbstractImpl#newConnectionFromDataSource InitialContext ic = new InitialContext(); ds = (DataSource) ic.lookup(jcd.getDatasourceName()); In the mapping of the jdbc-connection-descriptor you have to specify the jndi-name of the DataSource (to access the DB) defined on your appServer. It seems you set the name of your OJB access-class (bound to JNDI by yourself) instead. regards, Armin > > [Servlet Error]-[com/mydir/pkg/OjbPbStartup incompatible with > javax/sql/DataSource]: java.lang.ClassCastException: > com/mydir/pkg/OjbPbStartup incompatible with javax/sql/DataSource > at java.lang.Throwable.(Throwable.java) > at java.lang.Throwable.(Throwable.java) > at java.lang.ClassCastException.(ClassCastException.java:53) > at > org.apache.ojb.broker.accesslayer.ConnectionFactoryAbstractImpl.newConnectionFromDataSource(Unknown > Source) > at > org.apache.ojb.broker.accesslayer.ConnectionFactoryAbstractImpl.lookupConnection(Unknown > Source) > at > org.apache.ojb.broker.accesslayer.ConnectionFactoryManagedImpl.lookupConnection(Unknown > Source) > at > org.apache.ojb.broker.accesslayer.ConnectionManagerImpl.getConnection(Unknown > Source) > at > org.apache.ojb.broker.accesslayer.StatementManager.getPreparedStatement(Unknown > Source) > at org.apache.ojb.broker.accesslayer.JdbcAccessImpl.executeQuery(Unknown > Source) > at org.apache.ojb.broker.accesslayer.RsQueryObject.performQuery(Unknown > Source) > at org.apache.ojb.broker.accesslayer.RsIterator.(Unknown Source) > at org.apache.ojb.broker.core.RsIteratorFactoryImpl.createRsIterator(Unknown > Source) > at > org.apache.ojb.broker.core.PersistenceBrokerImpl.getRsIteratorFromQuery(Unknown > Source) > at > org.apache.ojb.broker.core.PersistenceBrokerImpl.getIteratorFromQuery(Unknown > Source) > at org.apache.ojb.broker.core.PersistenceBrokerImpl.getObjectByQuery(Unknown > Source) > at > org.apache.ojb.broker.core.DelegatingPersistenceBroker.getObjectByQuery(Unknown > Source) > at > org.apache.ojb.broker.core.DelegatingPersistenceBroker.getObjectByQuery(Unknown > Source) > at com.mydir.pkg.dao.tmpDAO.findByPK(tmpDAO.java) > at com.mydir.pkg.actions.UserLoginAction.execute(UserLoginAction.java:136) > at > org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:484) > at > org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:274) > at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482) > at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:525) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) > at > com.ibm.ws.webcontainer.servlet.StrictServletInstance.doService(StrictServletInstance.java:110) > at > com.ibm.ws.webcontainer.servlet.StrictLifecycleServlet._service(StrictLifecycleServlet.java:174) > at > com.ibm.ws.webcontainer.servlet.IdleServletState.service(StrictLifecycleServlet.java:313) > at > com.ibm.ws.webcontainer.servlet.StrictLifecycleServlet.service(StrictLifecycleServlet.java:116) > at > com.ibm.ws.webcontainer.servlet.ServletInstance.service(ServletInstance.java:283) > at > com.ibm.ws.webcontainer.servlet.ValidServletReferenceState.dispatch(ValidServletReferenceState.java:42) > at > com.ibm.ws.webcontainer.servlet.ServletInstanceReference.dispatch(ServletInstanceReference.java:40) > at > com.ibm.ws.webcontainer.filter.WebAppFilterChain.doFilter(WebAppFilterChain.java:61) > at > com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.handleWebAppDispatch(WebAppRequestDispatcher.java:974) > at > com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.dispatch(WebAppRequestDispatcher.java:564) > at > com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.forward(WebAppRequestDispatcher.java:200) > at com.ibm.ws.webcontainer.srt.WebAppInvoker.doForward(WebAppInvoker.java:119) > at > com.ibm.ws.webcontainer.srt.WebAppInvoker.handleInvocationHook(WebAppInvoker.java:276) > at > com.ibm.ws.webcontainer.cache.invocation.CachedInvocation.handleInvocation(CachedInvocation.java:71) > at > com.ibm.ws.webcontainer.srp.ServletRequestProcessor.dispatchByURI(ServletRequestProcessor.java:182) > at > com.ibm.ws.webcontainer.oselistener.OSEListenerDispatcher.service(OSEListener.java:334) > at > com.ibm.ws.webcontainer.http.HttpConnection.handleRequest(HttpConnection.java:56) > at > com.ibm.ws.http.HttpConnection.readAndHandleRequest(HttpConnection.java:618) > at com.ibm.ws.http.HttpConnection.run(HttpConnection.java:439) > at com.ibm.ws.util.ThreadPool$Worker.run(ThreadPool.java) > > > --------------------------------- > The fish are biting. > Get more visitors on your site using Yahoo!
