Using the Netbeans 6.5 profiler to profile a remote web app ?

Question

I'm having trouble using the Netbeans 6.5 profiler to profile the memory usage of a java web app, remotely.

I have followed the steps in the tutorial, and was able to customize a Tomcat instance to start with the profiling agents. I can also attach the Netbeans profiler to the running server: for some seconds, the profiler shows graphs with the memory usage of the server.

However, I am not able to run my deployed web app. After a few seconds, the server is shut down gracefully as if it simply had reached the bottom of its method main (hardly the expected behavior of a web server).

During these seconds, the server is not responsible, and I can't connect to a web application in it, they are simply not deployed.

I do not want to import my app into a new Netbeans project just for profiling it. It's possible to profile a remote app without access to its source, right ? After all, for a few seconds, the server was running and being profiled.

I want to profile a web application in Netbeans 6.5. What did I forget ?

Answer 1

Are profiling the entire webserver or did you use the profiling filter to profile only your package? Reducing the interaction between the profiler and the app server itself can solve it.
