Hi, We are migrating from WebSphere 5.1 to JBoss Portal 2.6.8. Here is our previous and new code: | String JNDINAME = "SMOnlineFacade"; | String URL = "jnp://localhost:1099"; | String FACTORY = "org.jnp.interfaces.NamingContextFactory"; | String PKG_PREFIXES = "org.jboss.naming:org.jnp.interface"; | | Object o = null; | SMOnlineFacadeHome home = null; | SMOnlineFacadeRemote smOnlineFacade = null; | | try { | Hashtable env = new Hashtable(); | | env.put(Context.INITIAL_CONTEXT_FACTORY, FACTORY); | env.put(Context.PROVIDER_URL, URL); | env.put(Context.URL_PKG_PREFIXES, PKG_PREFIXES); | Context initialContext = new InitialContext(env); | | o = initialContext.lookup(JNDINAME); // The object returned is of type $Proxy### | home = (SMOnlineFacadeHome) PortableRemoteObject.narrow(o, SMOnlineFacadeHome.class); | smOnlineFacade = home.create(); | | // Was previously | // org.apache.jetspeed.portlet.PortletContext portletContext = getPortletConfig().getContext(); | // SMOnlineDelegate delegate = null; | // org.apache.jetspeed.portlet.PortletService portletService; | // try { | // portletService = portletContext.getService(SMOnlineDelegate.class); | // delegate = (SMOnlineDelegate)portletService; | // } catch (Exception e) { | // e.printStackTrace(); | // } | By the delegating methods I mean our "interface" towards the backend. All our EJBs are deployd and bound to the correct JNDI's. I get the ClassCastException you see below... 15:27:30,890 ERROR [STDERR] Caused by: java.lang.ClassCastException 15:27:30,890 ERROR [STDERR] at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229) 15:27:30,890 ERROR [STDERR] at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137) 15:27:30,890 ERROR [STDERR] at com.te.unitor.portlets.VesselSearch.getRemoteFacade(VesselSearch.java:892) 15:27:30,890 ERROR [STDERR] at com.te.unitor.portlets.VesselSearch.getOnlineDelegate(VesselSearch.java:970) 15:27:30,890 ERROR [STDERR] at com.te.unitor.portlets.VesselSearch.init(VesselSearch.java:132) 15:27:30,890 ERROR [STDERR] at org.jboss.portal.portlet.impl.jsr168.PortletContainerImpl.initPortlet(PortletContainerImpl.java:359) 15:27:30,906 ERROR [STDERR] at org.jboss.portal.portlet.impl.jsr168.PortletContainerImpl.start(PortletContainerImpl.java:233) 15:27:30,906 ERROR [STDERR] ... 73 more 15:27:30,906 ERROR [STDERR] Caused by: java.lang.ClassCastException: $Proxy314 15:27:30,906 ERROR [STDERR] at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:212) 15:27:30,906 ERROR [STDERR] ... 79 more Thanks, Petter View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4246990#...
