I did get JVisualVM to work with Tomcat running as a service, but I don't think you're going to like it (to paraphrase Douglas Adams). First, the Tomcat service needs to be running under the same Windows account that JVisualVM is started with; JVisualVM cannot find the PID otherwise, and heap profiling doesn't seem to be available through JMX ports (or maybe I just don't know how to configure it). Second, you'll need to run Tomcat under JRE/JDK 1.6. JVisualVM can access Tomcat running under a 1.5 JRE, but heap profiling won't be available. So, the easiest thing may well be to just run Tomcat from the command prompt for the duration of the profiling effort. Since heap profiling has a significant performance impact, you wouldn't want it on very long anyhow. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
