Hi all,

We have Java enterprise application running on Tomcat 4.1.12. I need some Profiler tool that helps me to tune some parts of the application. I tried some open source but they seem to have limited features or not working correctly. I will be grateful if any of you can advise me on some commercial ones that work with Tomcat(still we are limited on using Tomcat 4.1.12 and JDK 1.4)....
Thanks in advance

I have just released the open source JAMon 2.0 (Java Application Monitor) tool.

Changes include:

- Better performance.
- A much better API for getting data out of JAMon.
- User defined ranges.
- A new MonitorFactory.add(...) method that allows for tracking things besides time (free memory, purchases for the day, exceptions thrown and much more)
- A much improved JAMonAdmin.jsp file that uses the FormattedDataSet to display and query JAMon stats.
- A cleaner/simpler implementation
- See for a more thorough accounting of what is new in JAMon 2.0

Downloading JAMon 2.0 as we speak - many thanks to Steve for upgrading and maintaining this valuable toolset. If you need fine details of whats going on in your application, take a look at JAMon.

Thanks for the support.

I have added an acknowledgements section to the JAMon site and mentioned Java Ranch.
