[jboss-user] [JNDI/Naming/Network] - PortableRemoteObject.narrow() returns null

Hello, I fairly assume this problem is related to my other topic "RMI-IIOP": I've deployed a Stateless SessionBean using IIOP bound to JNDI "mytest/MyBean" (even verified by JNDIView). I've implemented a C#-Client, on which I can look it up and access it, no problem. But with a Java-Client things just won't work. I can look it up and get an instance of "org.omg.stub.javax.ejb._EJBHome_Stub" returned. But PortableRemoteObject.narrow( obj, MyBeanHome.class ) 'ing the reference to my Home-Interface "MyBeanHome" returns NULL, so i always get a NullPointerException when calling home.create(). I've included the jbossall-client.jar to classpath. Nevertheless, compared to other source-examples it seems to me there's no mistake: public static void main(String[] args) throws Throwable { | | props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); | props.put(Context.PROVIDER_URL, "jnp://localhost:1099" ); | props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" ); | Context ctx = new InitialContext( props ); | System.out.println( "Got InitialContext!" ); | | String jndi = "mytest/MyBean"; | Object obj_ref = ctx.lookup( jndi ); | System.out.println( "Got Reference for : " + jndi ); | System.out.println( "Class : " + obj_ref.getClass() ); | | MyBeanHome home = (MyBeanHome)PortableRemoteObject.narrow( obj_ref, MyBeanHome.class ); | MyBean mybean = home.create(); | System.out.println( "Got MyBean: " + mybean.getTime() ); | | } Same, i cannot access MyBean from another SessionBean - same result: PortableRemoteObject.narrow() returns NULL. The problem persists on JBoss 4.0.0, 4.0.3 and 4.0.4. JDK: 1.5.0 I'm using the "all" - profile (since IIOP-support and -all- services are included) The only thing i've modified is, that i've commented out "<jnp-context>iiop</jnp-context>" in the IIOP-invoker-proxy-binding - Section in StandardJBoss.xml I can't figure out it must be that a problem since I think it is common that EJBs are ACCESSIBLE by clients or other EJBs ;-) Any hint is warmly appreciated!
