[jboss-user] [JNDI/Naming/Network] - ClassCastException in remote EJB3.0 lookup from tomcat webap

Hi everyone, I am trying to connect to an EJB3.0 remote session bean (deployed in an ear on JBoss V4.0.5) from a tomcat V5.5 webapp. The tomcat and the JBoss installation are deployed on different machines. I get the following ClassCastException in a call to PortableRemoteObject.narrow: java.lang.ClassCastException at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229) Caused by: java.lang.ClassCastException: javax.naming.Reference at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:212) Here is my client code: String urlName = "jnp://156.135.155.156:1099"; Properties p = new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory"); p.put(Context.PROVIDER_URL, urlName); p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); InitialContext ic = new InitialContext(p); Object ref = ic.lookup("SDOCIBusinessApp/SDOCIBusinessServiceImpl/remote"); SDOCIBusinessService narrowed = (SDOCIBusinessService )PortableRemoteObject.narrow(ref, SDOCIBusinessService.class); Here is the list output of jmx-console: Global JNDI Namespace +- HASessionState (class: org.jnp.interfaces.NamingContext) | +- Default (class: org.jboss.ha.hasessionstate.server.HASessionStateImpl) +- TopicConnectionFactory (class: org.jboss.naming.LinkRefPair) +- jmx (class: org.jnp.interfaces.NamingContext) | +- invoker (class: org.jnp.interfaces.NamingContext) | | +- RMIAdaptor (proxy: $Proxy52 implements interface org.jboss.jmx.adaptor.rmi.RMIAdaptor,interface org.jboss.jmx.adaptor.rmi.RMIAdaptorExt) | +- rmi (class: org.jnp.interfaces.NamingContext) | | +- RMIAdaptor[link -> jmx/invoker/RMIAdaptor] (class: javax.naming.LinkRef) +- SDOCIBusinessApp (class: org.jnp.interfaces.NamingContext) | +- SDOCIBusinessServiceImpl (class: org.jnp.interfaces.NamingContext) | | +- remote (class: java.lang.Object) | | +- remoteStatefulProxyFactory (proxy: $Proxy87 implements interface org.jboss.ejb3.ProxyFactory) | +- ExcelConverterImpl (class: org.jnp.interfaces.NamingContext) | | +- local (proxy: $Proxy79 implements No ClassLoaders found for: ch.skyguide.aim.interfaces.businesslogic.converter.ExcelConverter (no security manager: RMI class loader disabled)) | +- IBriefingExportInvokerImpl (class: org.jnp.interfaces.NamingContext) | | +- local (proxy: $Proxy82 implements No ClassLoaders found for: ch.skyguide.aim.interfaces.businesslogic.exportinvoker.IBriefingExportInvoker (no security manager: RMI class loader disabled)) I have packaged the EJB plus interfaces in an SDOCIBusinessApp.ear to be deployed on jboss and also as a jar in the WEB-INF/lib directory in the war file of my webapp since the webapp needs to reference the interface SDOCIBusinessService. I have read all sorts of posted topics which seem to deal with this ClassCastException but I haven't found the solution to my problem yet. Can anybody help?
