In EJB/CORBA integration, complexity can range from simple to complex and depends in part on the direction of the communication. From EJB to CORBA, communication is relatively simple because the EJB bean invokes CORBA as it does any external resource. CORBA-to-EJB communication, however, depends on the application server's support of RMI-IIOP. If the application server doesn't support RMI-IIOP, then it's best to create a wrapper or adapter class that redirects or delegates the function calls from the client via a CORBA servant, which then calls the EJB. Part 1: EJB/CORBA Integration Communicating from EJB to CORBA is the simplest case. The EJB will require an ORB and some means of looking up the remote CORBA object, the servant, in a directory service that could be CosNaming or JNDI over CosNaming. Note: It isn't necessary to use CORBA 2.3, which is required by RMI-I... (more)
