Whatis the ORB?

TheObject Request Broker (ORB) is the central component of CORBA. The ORB provides the
requiredinfrastructure to identify and locate objects, handle connection management, deliver
data,and request communication.
ACORBA object never talks directly with another. Instead, the object makes requests through a
remotestub to the ORB running on the local machine. The local ORB then passes the request to
anORB on the other machine using the Internet Inter-Orb Protocol (IIOP for short). The
remoteORB then locates the appropriate object, processes the request, and returns the results.
IIOPcan be used as a Remote Method Invocation (RMI) protocol by applications or objects
usingRMI-IIOP.Remote clients of enterprise beans (EJB modules) communicate with the
EnterpriseServer via RMI-IIOP.

IIOP Listeners

AnIIOP listener is a listen socket that accepts incoming connections from the remote clients of
enterprisebeans and from other CORBA-based clients. Multiple IIOPlisteners can be
conguredfor the Enterprise Server. For each listener, specify a port number, a network
address,and optionally, security attributes.
