Local ejb access vs remote access
msecrist Nov 7, 2008 11:07 AMI'm trying to figure out why remote access to my EJB works but local access doesn't seem to. If I create a test remote test client using the following code, everything seems to work fine.
Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); env.put(Context.PROVIDER_URL, "jnp://localhost:1099"); try { LeagueFacade leagueFacade = LeagueFacadeUtil.getHome(env).create(); League league = leagueFacade.findLeague(1);
If I use the following code in a jsp or servlet deployed as part of the same EAR into the Jboss container, I get an exception (failing on the call to LeagueFacadeUtil.getHome() ).
LeagueFacadeHome h = LeagueFacadeUtil.getHome(); LeagueFacade l = h.create(); League league = l.findLeague(1); Iterator schedules = league.getSchedules() .iterator();
java.lang.ClassCastException com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(Unknown Source) javax.rmi.PortableRemoteObject.narrow(Unknown Source) com.leagueplanet.ejb.LeagueFacadeUtil.lookupHome(LeagueFacadeUtil.java:25) com.leagueplanet.ejb.LeagueFacadeUtil.getHome(LeagueFacadeUtil.java:42) org.apache.jsp.schedule_jsp._jspService(schedule_jsp.java:78)
If I try to add an initial context environment as I did for the remote client, I get a different exception and it fails on the call to LeagueFacadeHome.create()
root cause java.rmi.ServerException: EJBException:; nested exception is: javax.ejb.EJBException: Invalid invocation, check your deployment packaging, method=public abstract com.leagueplanet.ejb.LeagueFacade com.leagueplanet.ejb.LeagueFacadeHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException org.jboss.ejb.plugins.LogInterceptor.handleException(LogInterceptor.java:365) org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:136) org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invokeHome(ProxyFactoryFinderInterceptor.java:107) org.jboss.ejb.SessionContainer.internalInvokeHome(SessionContainer
I'm obviously missing something but can't quite figure out what it is. BTW, this is the basic code from the WTP book, which was aimed at a JBoss 4.0 deployment.
Thanks,
