Updated to call the remote EJB over CORBA

I needed to remove @Override as it turns out that implementing an interface doesn't allow @Override

Anway, the main changes are:
1. Configured harness/ejb2 to use EJB2
2. Configured rmic
3. Removed the api from the application.xml  in ear1
4. Configured the classpath of ear1 correctly

Hope that helps,
Tom
