Abstract:

In order to solve the single form and the huge complexity existed in the integration process of the enterprise application.The integration methods based on EJB3.0(Enterprise JavaBeans) are also discussed. According to the characteristics of EJB3.0,the integration modes and the implementation of the three integration methods are presented. Based on the above studies, a comparison is made,and the superiorities and deficiencies of each integration methods and their application scope are discussed. By studying and comparing the integration methods of EJB3.0, the solution of how to use these methods rationally in practice is given. Combining with the theory of services oriented architecture and the integration methods of EJB3.0, the analysis of their relations is given, and a referential suggestion of how to adopt the integration methods in SOA(Services Oriented Architecture) is provided.

Key words: enterprise javabeans(EJB3.0), java message services(JMS), Web service, J2EE connector architectur(JCA), services oriented architecture(SOA)
