Integration of enterprise applications is not only theintergration of different networks,computer software and hardwareplatforms.Integration at the level of application softwares is moreimportant.Technology of distributed object is a kind of integrationtechnology of applications.It is the combination of object technologyand distribution technology.CORBA specification proposed byOMG is a new generation of specification of distributed compute.Itintroduces concept of broker.It realizes the transparency ofreceiving request and returning response.It realizes the separation ofclient program and server program.It supplys the mechanism ofsoftware bus .Every application or software system can beintegrated with CORBA system as long as the system's wrappers arein compliance with CORBA interface specification theoretically.Butthere are some problems during the inetroperation of CORBA inheterogeneous environment.This is the obstacle of using CORBA inenterPrise aPplication integration.. In this thesis I analyse some problems of CORBAinteroperation in heterogeneous environment and find out thesolution to the problems.I construct a heterogeneous CORBAenvironment.I solve some of the problems encountered in theCORBA interoperation of heterogeneous environment and realizethe interoperation between Java application and C++aPplication.This i11teroperation provide the theory and experimentbase fOr enterprise aPplication integration based on CORBA.In thisthesis I propose a method of enterPrise application integration baseuon CORBA interoperability.With the progress of lntranet inetherprises,the illtegration between enterPrise aPplication and Webbecome an imPortam part of enterPrise applicatiQn integration.In thisthesis I propose the method of integration between eflterpriseaPplication and Web by combining the technology of J2EEarPhitecture and the existing theories.EJB is a server-side componentmodel proposed by sun Microsystems.Many enterprises haveiforoduced EJB technology to construct enterPrise aPpl:ications.Thisthesis researched the iflteroperation between EJB and CORBA,andProposed a model of the integration between EJB aPplication andother enterPrise aPplication.
