The invention relates to a complete network middleware operation support platform which can be used for integrating a plurality of conventional mainstream middleware technologies, and a method for integrating a heterogeneous middleware member on the platform. The platform disclosed by the invention comprises a microkernel integration frame, a communication service layer, a public service layer, a member container layer and a service engine layer, wherein the microkernel integration frame provides upper-level service integration interface specifications of a life cycle management and command interface, an interoperation interface and a deployer interface needed for deploying specific components, for the four categories of service layers. According to the invention, deep integration of mainstream middleware technologies, such as JEE (Java Enterprise Edition), Web service, CORBA (Common Object Request Broker Architecture), COM/DCOM (Component Object Model/Distributed Component Object Model), and the like, is realized. The complete network middleware operation support platform and the integration method of the heterogeneous middleware can be widely applied to integration of different application service technology systems.
