Ejb Server Transaction Services Are Designed To Achieve

With the development of the computer networks , the application development based on the technology of middle-ware has been used widely for improvement its reusing and stability. Many companies has implemented their own middle-ware application server products to supply good environment for users. The J2EE application server is one of middle-ware application servers. The J2EE application server implement multi-layer architecture , across different platform, simplifying the enterprise solution of development, deployment and management. Specially, the Business logic Tier Which is separate by J2EE application server make software reusing easy. Today, the research about the technology of J2EE is not mature in civil, and the article give some research about it.The EJB server is a core part of the application server, it provide an environment for the EJB components deployment and running, this environment include many standard services and container, and the transaction service is one of core services, this article narrate the technology of EJB, the architecture of the EJB application server, and analyze the transaction service' s specification JTS/JTA in detail. Based on the analyses, the article design a model of the transaction service, and implement them.
