I would like to profile an application that runs on Tomcat with the VisualVM tool. Unfortunately, when I tell VisualVM to profile Tomcat, Tomcat prints out a couple of messages indicating it is connecting to a profile tool and then simply exits.
Details…
I am using Windows XP, Tomcat 6, VisualVM 1.2.1, and JDK 1.6.0_11.
- In Visual VM, I right-click on the Tomcat Application and select “Profile”
- In the Profiler Tab, I press the Memory button (or the CPU button).
- Tomcat exits
Note that if I right-click on the Tomcat Application and select “Heap Dump” that seems to work OK.
