Research On The EJB Application Server

With the development of informationization, many enterprise build a series of MIS applicaton for meet the need of managing its source. The architecture of the J2EE is becoming the most popular solution of the enterprise development. The articleis on this background to tell about how to use the JMX tool providing by SUN, complishing the module of the J2EE server. I will give the solution of developing the EJB server under the J2EE architecture, and maybe analyse the inner mechanism. In this process, I would choose the tool of the JSDK5.0 providing by SUN.In this thesis, in the first place, I analyse the characteristic of the J2EE architecture, especially the EJB server. After analyse the mechanism of the EJB container, I found the disadvantage of the passivation/ activation mechanism, and give my solution to this disadvantage. Finally, I give a solution to the EJB server, and improve the performance of the process in the mechanism of the stateful EJB's passivation and activation.This thesis is based on an application server model - HHUKServer. This module base on the JMX platform. This model can be used to implement the function such as deploying the Beans, using the RMI to call the server and the pool of the EJB object. This model improve the performance of the process in the mechanism of the stateful EJB's passivation and activation.The following contents are included in the thesis:1. To elaborate on deployment technology based on a thorough research on J2EE Platform specification, EJB specification, management specification and key technology of application server.2. To expatiate the mechanism of the deployment tool based on a systems analysis on several application servers such as JBoss, WebLogic and Sun J2EE Application server.3. To research the mechanism of the EJB server and find the disadvantage of the of the passivation/ activation mechanism. To analyse this matter and give a solution to improve this function.4. To design a simple module of EJB server. To expatiate the design pattern of the EJB and the implementation of module of this EJB server. To improve the performance of the process in the stateful EJB's passivation and activation. To compare with the mainstream EJB server and To give the conclusion in this phase. .
