Corba

[ollka]

Hi,

I'm trying to find answer on using ejb3 with corba.

With ejb2.1 it works fine, i set up iiop invoker in jboss.xml and my bean register at corba naming service.

But i cannot find any possibility to do it with ejb3.

Please, give me some links or advices to work woth ejb3 and corba.

Thanks.

[wolfc]

To make a bean available over iiop use:

@RemoteBinding(factory=org.jboss.ejb3.iiop.IORFactory.class)

[ollka]

Thanks for your answer.

And where I can find org.jboss.ejb3.iiop.IORFactory.class?
I have tried almost all of jboss libs but there is no such class...

[wolfc]

deploy/ejb3.deployer/jboss-ejb3.jar

[ollka]

And what name component should i use to resolve my bean?

with ejb2 in deploying log i could see iiop and jndi name
[Home IOR for MyBean bound to ejb/MyBean in JNP naming service
Home IOR for MyBean bound to iiop/ejb/MyBean in CORBA naming service]
, but now i can see nothing.

I know jndi names, to that it binds automaticly, but what iiop name?

[ollka]

And should my Remote interface implements java.rmi.Remote?

When i try to use REmoteBinding in Bean Metadata, i have following:

When i use it before my remote interface, i have not such exception, so i think it doesn't work in that way...

[wolfc]

The JNDI names and Corba Naming names are equal.

So: HomedStatelessBean/home or MyStatelessBean/remote

[ollka]

What about exception?

When i try to use same name, i have org.omg.CosNaming.NamingContextPackage.NotFound exception.

I tryed to use RemoteBinding before remote interface and before bean.
In first case i have no exceptions while deploying, but nothing happens when i try to resolve by bean (i have NotFound exception)

In the second case i have exception, listed in my previos post, so i think, something doesn't work and it doesn't boud to corba naming service, or smth else happens, but result is the same - i have NotFount exception on my client.

[wolfc]

The bean must comply to EJB 2.1 API, so the Remote interface is mandatory. In JBoss the home interface is optional.

To lookup the bean I use the following properties:

Properties props = new Properties();
 props.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
 props.put("java.naming.provider.url", "corbaloc::localhost:3528/NameService");
 props.put("java.naming.factory.object", "org.jboss.tm.iiop.client.IIOPClientUserTransactionObjectFactory");
 props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming.client:org.jnp.interfaces");

[ollka]

Maybe i don't understand something...

Look
example of myBean
I have
@Remote
public interface MyBeanRemote extends java.rmi.Remote {...}

@Stateless
@Remote({MyBeanRemote.class})
@RemoteBinding(factory=org.jboss.ejb3.iiop.IORFactory.class)
public class MyBean implements MyBeanRemote {...}

When i deploy this - i have exception listed before (org.omg.PortableServer.POAPackage.AdapterAlreadyExists: IDL:omg.org/PortableServer/POA/AdapterAlreadyExists:1.0) (but bean is deployed)
And when i try to resolve bean from client, using your properties, i have NotFound exception.

If i try to move @REmoteBinding to MyBeanRemote interface, i have no exceptions but still have NotFound exception.

[ollka]

As i understand, my exception is a result of "double" binding to the same name. I don't know, why it happens, but it occurs only when i redeploy my ejbs.

If i restart whole server, i have another exception:
java.lang.ClassCastException
at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
at org.jboss.ejb3.iiop.IORFactory.createProxy(IORFactory.java:154)
... 136 more
Caused by: java.lang.ClassCastException: Object is not of remote type javax.ejb.EJBObject
at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:221)
... 138 more

If i use EJBObject - i have ejb2, isn't so?

[ollka]

And even if i implements EJBObject and all callback methods, i still have the same exception

[ollka]

No ideas?

[ollka]

Problem solved by patching file IORFactory (in jboss-ejb3.jar)
Method createProxy make return CORBA.Object, don't narrow to EJBObject

[ghz_gordo]

Hello ollka !!

I have the same problem..

and, if is possible, i want to know how u patching the file IORFactory...

or somebody know how solve this problem ?

thx a lot !!!
