communication between two web app

[joe380]

Hello,
I would like to ask if it is possible to let two (or more) web applications communicate between each other in the same container on a simple interface base, without rmi(@remote) or @webservices. Of course using seam!
To be more exact, lets say one deployed application(app A) should be as a server and as second deployed application(app B) should use some services from app A(app B should be possible to invoke business methods of app A through an interface).

Im asking if it is possible, if so were can I find more info about this concrete problem(communication among app in the same container) or which way should I go/look/made my research/what words should I google, etc?(I know it is possible through mentioned rmi, or webservices, the point is to find other way using seam, because I heard that it should be possible but how it wasnt sad:)

Yes, EJB3 allows you to communicate using remote interfaces and JNDI lookups.

Thanks,
and my second question is that if it is possible through remote interfaces and jndi lookups. Is it possible using it only together or these are two ways of solving this problem separately?
