Could you give me an example which a java client access EJB by RMI/IIOP!
Thank you very much!

Hi!

It's not complete example (no imports and so on).
Ah and don't forget to change jboss.xml for IIOP

public class SCTest
{
private final static String factory = "com.sun.jndi.cosnaming.CNCtxFactory";
private final static String provider = "IOR:"; // JBoss ns IOR

public SCTest()
{
Properties env = new Properties();

env.put(Context.INITIAL_CONTEXT_FACTORY, factory);
env.put(Context.PROVIDER_URL, provider);

try
{
InitialContext ctx = new InitialContext(env);

m.getMunicipioList();

java.lang.Object obj = ctx.lookup("MyEJB");
MyEJBHome home = (MyEJBHome)PortableRemoteObject.narrow(obj, MyEJBHome.class);

MyEJB my = (MyEJB)home.create();

my.hello();
}
catch (Exception ex) {System.out.println(ex);}

}
public static void main(String[] args)
{
new SCTest();
}
}

Cheers,

Hem...

Thank you Jim,but when I run my test program like yours it throw exception

Corba name:org.jacorb.orb.ORB
java.lang.ClassCastException
at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:296)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
at newejb.Enterprise1TestClient1.(Enterprise1TestClient1.java:50)
at newejb.Enterprise1TestClient1.main(Enterprise1TestClient1.java:192)-- Failed initializing bean access.

I find the object which I get from "ctx.lookup" is a "_EJBHome_stub" it cann't be casted to MyEJBHome .

I feel very worry about it,please help me!

Hola!

Something wrong with the forum...

Well, I think you just forgot to include your RMI/IIOP stubs into the classpath (compile your interfaces with rmic -iiop). Regarding the '_EJBHome_stub' - it's OK you need to narrow it to get a 'home' object.

cheers,

Hi!

It is no so simple... I think the problem exists, but have no idea where... :-(
