I am into development of NMS (Network Management System) using J2EE. When I have seen there are numorous resources about this like uring JMX, JDMK. But I need some small help regarding the application. At present I have planned to use JMX, JDMK (jsnmp.jar) for getting the element (swich, router, gateway SNMP supported) details and inserting them into the database and showing the Graphs (JfreeChart) with the collected data. But I donno what is the use of MBean & all. Where exactly I can use MBean for my above application and how? Can anybody help me in this.. Thanks a lot in advance. With Regards, george.
