Open Source Java Profilers
Ah. Netbeans Profiler, developer.com's "Product of the Year" winner, in 2009.
The VisualVM which comes with jdk6 has a basic profiler inside it. VisualVM is provided with the jdk, so if you have the jdk6 installed, you likely have it installed as well.

Java has a basic built in profiler called HProf. I find it useful to compare the results it provides with results from more fully features profilers.
