We are attempting to invoke CORBA from within XI, and we are
encountering some issues.
1. SAP Netweaver does not define env:comp/ORB defined in JNDI to lookup
the server orb. When I try to retrieve the name, the orb returned is
null.
2. The ORB provided by SAP doesn't seem to understand
corbaname/corbaloc URLs. We use the following properties
org.omg.CORBA.ORBClass="com.sap.engine.system.ORBProxy"
org.omg.CORBA.ORBSingletonClass="com.sap.engine.system.ORBSingletonProxy"
We need to know if these are known issues or if the configuration is
wrong or if we are specifying the ORB correctly. Any help you can
provide or documentation you can refer us to would be appreciated.
Some additional information here
Symptom
The ORB implementation of EJB containers conflicts with OrbixWeb bundled in Java RFC.
Additional key words
Orbix CORBA Enterprise JavaBeans
Cause and prerequisites
Java RFC release 4.5A to 4.6B uses a CORBA middleware implementation
using Iona's Orbix and OrbixWeb. When trying to wrap JRFC code into
enterprise JavaBeans to be deployed in an EJB container, if the
container is implemented using a CORBA ORB, it will conflict with
OrbixWeb.
Solution
Currently there is no solution for the ORB conflict between
Orbix and EJB containers.
We will be delevering a JNI implementation of JRFC in 4.6C, which
will be more apporpriate for server side Java, and will not
cause any ORB conflicts with EJB containers.

Can you also tell us the reason behind corba usage, if possible i would try to avoid taking that route, i have done a couple of migrations for clients out of IBM crossworlds that uses corba.....and into xi.
