12. Servlet as an rmi client    coderanch.com

It sounds like the user, under which your container is running doesn't have sufficient permissions to access the the network resource in question. Personally, I wouldn't do this directly in a servlet. I would make the RMI client a plain old Java object that can be instanciated by any interface (command line, servlet, etc...) to have it's methods called. This will ...

16. RMI using servlet    coderanch.com

RMI is not simple enough for someone just to paste an example in here. Before worrying about doing this from a servlet, you get a basic understanding of RMI and get it working in a plain old Java class. Once you can do that, it should be fairly simple to invoke that class and call its methods from a servlet.

30. Is Rmi a stateless protocol?    coderanch.com

Jacob, One RMI server is shared between multiple "concurrent" clients and RMI connections do not implement a notion of a session. Stateful session beans implement a tighter coupling under the hood across RMI via protocol mechanisms similar to what you would have to roll out by hand. Definitely think RMI is very applicable where binary based communication between Java/ORM/CORBA clients are ...

But didnt know what to answer for this question to interviewer. Thanks anyways for the reply.
