To ALL J2EE Guru's,

I am getting some problems in looking up my beans local home interface(Details under), however when I look up the remote home interface its fine. Please look into my problem when you have a minute. Appreciate your help.
---------------------------------- Details --------------------
1. I have 2 beans, one stateful, other stateless and both have remote and local interfaces
2. I can access both using remote interfaces but not using local interfaces
3. However TestClient works fine for both Remote and Local interfaces:

Followings are the urls TestClient looks up:

Stateless Bean remote Interface:

http://localhost:9080/UTC/jndiLookup?name=com/selectica/configejb/CxConfigStatelessHome&random=0.032660621190745975

Stateless Bean LocalInterface:

http://localhost:9080/UTC/jndiLookup?name=local:/ejb/com/selectica/configejb/CxConfigStatelessHome&random=0.32728747419322335

In my client program I used following JNDI:

I. For looking up remote home : com/selectica/configejb/CxConfigStatelessHome (Works OK)
II. For Looking up local home: local:ejb/com/selectica/configejb/CxConfigStatelessHome (throws following exception)


javax.naming.ConfigurationException: NamingManager.getURLContext cannot find the factory for this scheme: local
at com.ibm.ws.naming.jndicos.CNContextImpl.checkForUrlContext(CNContextImpl.java:2770)
at com.ibm.ws.naming.jndicos.CNContextImpl.lookup(CNContextImpl.java:1220)
at com.ibm.ws.naming.util.WsnInitCtx.lookup(WsnInitCtx.java:132)
at javax.naming.InitialContext.lookup(InitialContext.java:359)
at GetServiceProgramsLocal.getEJBObjectHandle(GetServiceProgramsLocal.java:130)
at GetServiceProgramsLocal.main(GetServiceProgramsLocal.java:54)


4. My Client module and ejb module are in same .ear.
5. I have created local references (Deployment descriptor is pasted below)

Some more Details:

Look up Code:


private static CxConfigLocalStateless getEJBObjectHandle() throws NamingException, CreateException, RemoteException {
CxConfigLocalStateless config = null;
final InitialContext ic = new InitialContext(); // get initial context
final CxConfigLocalStatelessHome home = (CxConfigLocalStatelessHome) ic.lookup("local:ejb/com/selectica/configejb/CxConfigStatelessHome");
config = (CxConfigLocalStateless)home.create();

return config;
}
