[ben josh]

Hello all
I have application that uses Jboss as the ejb container that expose business service's API
I was reading that the remote methods invocation that ejb3 is using is something called RMI-IIOP
That could be accessed from corba client also.
My question is can it be done? and is it trivial way to do it , or better use web services
The resone I want to use corba is that the third party application already using CORBA as her way of remote method
