Design and implementation of the monitoring system for EJB applications based on interceptors

With the release of EJB 3.0 specifications, EJB technology has won more and more developer´s advocate. This paper designs and implements a monitoring system based on interceptors for EJB distributed applications in order to be able to grasp the EJB application system operating information, the timely detection of EJB application exceptions and make EJB applications to provide better services. The system uses EJB interceptors intercept the call information in order to achieve the EJB application monitoring. This paper will give the structure of the system design, the key points about how to achieve the system and key elements of the code. And finally demonstrate the system´s actual operating results.
