5 +Free and simple. I like the built-in sun monitoring tool. Java 1.5+ only.

7 +Simply add appropriate argument to your launch configuration:

10 +After that, open your unix terminal and type jconsole which launches the monitoring console and detects running java apps. Select your app and watch it at work. I like the Memory and Threads tabs.

19 19  If profiling on Windows is an option, you might also want to look at jSprint:

34 34  I use [[JProfiler>>http://www.ej-technologies.com/products/jprofiler/overview.html]] from [[ej-technologies>>http://www.ej-technologies.com]]. It works as well as any of the other big named profilers, and it has explicit support for WebObjects. It is, however, not free like some of the other suggestions.
