Question on EJBs:

If someone as deployed an EJB on a server, and I am trying to invoke one of its methods, what do I need to do this?

I have seen some examples of client code that do the following:

1.get InitalContext
2.using InitialContext get a reference to the home
3.Use the narrow() method to cast it down to the type you want.
4.Call the create() method on the home object to get a reference to the Remote inteface
5.Call the required methods on the remote interface.

Question: In step 3 where we cast it to the type that we want. Does this mean that I must have the Home class and the Remote class available to me?
Is this usually the case when a third party provides a EJB already deployed, do they give you the home and remote interfaces so that you can cast down to them?

hi
you must have the stub generated by the deployment tool to cast the object
and providers give only the stub of the bean deployed .
Cheers .
