RMI objects in WebSphere JNDI Namespace

[Nandakumar K S]

I am trying to integrate our application which has RMI services with
WebSphere 4.0.1 Advanced Edition.

In the process, a servlet launches the Application's RMI services.
Presently, a separate RMI Registry is brought up
along with the WebSphere Appserver and the application has methods that
binds and looksup (using JNDI) this RMI Registry to
access the services. To do this I need to have providerutil.jar and
rmiregistry.jar in my classpath so that the application
can bind or lookup for the RMI services using the initial context
factory - "com.sun.jndi.rmi.registry.RegistryContextFactory".
Note- Care is taken to not to have servelet as RMI server.

My goal is to avoid a separate RMI registry outside WebSphere
container. To do this, how can I make use of WebSphere's
RMI registry and also what is the JNDI Initial Context Factory for
accessing RMI objects?

Cheers & All:-)s

You might want to check out Custom Services if you need some startup service
to bind the names. The factory is
com.ibm.websphere.naming.WsnInitialContextFactory.
