Nice java profiler tool but unfortunately it is not free. One year ago, when I tried to tunning my java application I usually used jvmstats (free profiling tool from Sun) and completed with visualgc to view memory object in graphic (GUI). this tool is very useful and complete enough to tuneup your java application before put it into production environment.
Few days ago, I tried using JProfiler. It's very complex, you could see memory that java object used, CPU usage, thread usage and all of those was breakdown until method level. You could get much information which classes or methods that's consuming very high memory and detected memory leak. Finally you could snapshot the result into file and could open in any JProfiler GUI. Don't missed to try this tool since it still have trial version.
