This is a useful perspective. A categorical quibble: RMI seems to be of a similar sophistication to CORBA, having a naming service, stubs, etc. Are CORBA and EJB really similar kinds of things? And perhaps there is usefully a third level, for the marshalling/serialization tier: - SOAP is part method invocation; part XML serialization format. - RMI does method invocation (and lots of infrastructure); and uses Java's own Serialization. > Now that SOAP is on the scene; CORBA, EJB and COM+ don't go away, they just > have another way to pass information to and from objects. BTW: in support of this view, Java has a IIOP-RMI facility to interoperate with CORBA.
