can any one recomment a profiler that will help me to to the profiling onth at web application.

You can use any java profiler for this. I have personally used Dev Partner's java profiler but you can find open source tools as well.

Mainly depending on whether you want to profile memory or performance, you can choose appropriate product. To connect to your application, you need to tweak around the server configuration so that the server would be servicing on one specific port for profiling so that the profiler can connect to it from outside. You can check it in the profiler configuration steps.

can you please explain a bit more on how to configure the port and stuff. because am net in this area .

thank you
