hi, can anybody suggest me a way to take heap dump, which can help me to analyze and debug memory leak.
i tried jmap, but that information is not very helpful for me.

Taking a heap dump, when you don't know what is leaking, is probably not the best course of action. It is probably better to use a profiler and monitor the heap as the application is leaking -- to see what grows.

Regardless, you still need to understand the application, in order to understand what should be growing and what shouldn't be growing.

Try latest JProfiler. It is very stable and good at detecting memory leaks.

If you can't afford, you can check their trial version. However I would highly recommend it, if you can buy it.

I have used it and extremely happy with its stability compared to JProbe. I am not advertising or working in JProfiler.

Good article! About capturing heap dumps, HeapHero is also good. It is free web tool. You have to upload your your application's heap dumps & review the beautiful reports instantly.
