CORBA

TheEnterprise Server supports a standard set of protocols and formats that ensure
interoperability.Among these protocols are those dened by CORBA.
TheCORBA (Common Object Request Broker Architecture) model is based on clients
requestingservices from distributed objects or servers through a well-dened interface by
issuingrequests to the objects in the form of remote method requests. A remote method request
carriesinformation about the operation that needs to be performed, including the object name
(calledan object reference) of the service provider and parameters, if any, for the invoked
method.CORBA automatically handles network programming tasks such as object
registration,object location, object activation, request de-multiplexing, error-handling,
marshalling,and operation dispatching.
