Will it work with any Application server?

[Venkata Raaman]

or only at?? what are other advantages than resource mgmt? memory mgmt?

[Maneesh Godbole]

In case anyone else is confused (like I was) this question appears to be related to the Java-Monitor.

[Ulf Dittmer]

It does; see Kees' answer here. The point is not so much management as monitoring. Java-monitor is not a JMX client that would allow you to change anything about the server environment. It allows you to monitor a JVM, and can alert you if it's not reachable.

[Kees Jan Koster]

Dear Venkata,

It goes further than that. If you have a JVM that is not a servlet container, you can also enable monitoring from code. Just unzip the WAR file and add the code to your own project.

  final JavaMonitorCollector collector = new JavaMonitorCollector("1234");
  collector.start();

There's more talk about that here: http://java-monitor.com/forum/showthread.php?t=2879#4
