[jboss-user] [Beginners Corner] - ClassCastException with PortableRemoteObject.narrow call

I want to call an ejb component located on a different machine and I can not get it to work. So I tried to deploy it under local copy of jboss and try to invoke it. I was able to call it. So i tried adding Context.PROVIDER_URL with my localhost set. I always get the ClassCastException. If I am remove the line from below everything works fine. String host = "jnp://localhost:1099"; props.setProperty(Context.PROVIDER_URL, host); 2006-11-03 10:17:18,319 ERROR [STDERR] java.lang.ClassCastException 2006-11-03 10:17:18,319 ERROR [STDERR] at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narr ow(PortableRemoteObject.java:229) 2006-11-03 10:17:18,319 ERROR [STDERR] at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObjec t.java:137) As soon as I uncomment that props.setProperty(Context.PROVIDER_URL, host); line everything works fine. I have seen this type of exception before when I tried invoking the ejb on a different computer as well. When I inspect the object with reflection I see that it found the right remote home interface. This is my code: Properties props = new Properties(); props.setProperty(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.security.jndi.JndiLoginInitialContextFactory"); props.setProperty(Context.SECURITY_PRINCIPAL, "admin"); props.setProperty(Context.SECURITY_CREDENTIALS, "admin"); props.put(javax.naming.Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); String host = "jnp://localhost:1099"; props.setProperty(Context.PROVIDER_URL, host); ctx = new InitialContext( props ); Object object = ctx.lookup( "ejb/com/blah/Manager" ); ManagerRemoteHome home = (ManagerRemoteHome)PortableRemoteObject.narrow ( object, ManagerRemoteHome.class); ManagerRemote manager = home.create(); Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3983151#...
