EJB Hot-Deployment Base On Interceptor Technology

EJB and JavaBean technology are located in the middle of the J2EE architecture, they are the bridge between the database and the JSP pages.The traditional method for EJB deployment is stop the working of the server and then do the deployment work. However, within the development of the application form, the deploy method must develop follow the changing. So, the fit deployment process should be keep working while deploy and not interrupt the working of the server.EJB container is a tool for EJB arrangement and management, the relationship between them is strong, that is to say, every EJB have interface with EJB container and each other. Just because the strong relationship, the implement of hot deployment holdback. Because mend any EJB should impact other one or more. It's hard to change the relationship, EJB container is encapsulated by each factory.Interceptor is introduced by CORBA 2.2 edition, it can be used as monitor for lifecycle. The system which used interceptor could add serve by itself and the agility of the software is approved. The article use the excellence of stack spring mode bring forward a kind of mode between interceptor and EJB container. The mode by use of interceptor to instead of EJB container to manage the EJB. Finally I experiment base the mode and implement the hot deployment of EJB.The research of the article is how to use the interceptor technology to implement the hot deployment of EJB, it's worth of research for application.
