Google and read about JMX.

thank u .
i read the jmx.i worked the examples but it is used to monitor the same application
but when more that one application is running how can i monitor the particular application memory usage and the cpu time

[r035198x]

Just get a profiler then. There's lots out there.

i am creating the application to monitor.so pls help me in those.only one thing i want to know is that how to monitor the particular application memory usage using another

That's what a profiler does. Go look into how you can profile Java apps...look up instrumentation, for example.

thanks fro d reply
for example
MonitoredHost local = MonitoredHost.getMonitoredHost("localhost");
MonitoredHost local1 = MonitoredHost.getMonitoredHost("localhost");
Set vmlist = new HashSet(local.activeVms());
Set vmlist1 = new HashSet(local.activeVms());
for (Object id : vmlist) {
MonitoredVm vm = local.getMonitoredVm(new VmIdentifier("//" + id));

String processname = MonitoredVmUtil.mainClass(vm, true);
System.out.println("id number"+vmlist.size());
System.out.println(id + " ------> " + processname);
System.out.println("vmlist:"+vmlist);
this gives me the no of processname n id that was running on the Jvm
how can i create an application that monitor the particular process or
help me placing the process information on to the table on runtime
