Corba, Web Application And Ejb Integration

Distributed object technology has become the mainstream technology and an important computing paradigm of application integration and system development in distributed heterogeneous environment. To integrate CORBA into Web can make full use of the advantages of both technologies and bring high efficiency to Web application.This paper focuses on the principle and architecture of CORBA, also on the mainstream component technologies. The author designs and implements an online product-show system with CORBA architecture and J2EE Servlet technology. The system not only has the advantages of traditional CORBA, good maintainability and extensibility; also meets the demand of the Web application of CORBA. Also, the system improves some module with the CORBA services. Then this paper goes on to study the integration of CORBA and EJB. To integrate CORBA and EJB makes it possible for CORBA system to take use of the EJB legacy resources in J2EE system, also this will enhance the ability of expansibility and compatibility to non-Java system in J2EE. This paper studies and analyses some ways of the integration, then implements a certain method in the system.
