Answer 1

I was having the problem having of visualvm detect my local tomcat installation on Windows 7. I could connect manually, but then things like memory snapshots and visualgc plugin were not enabled. I confirmed that I was using same JVM version, temp file permissions, etc. Didn't work. Then I found that starting visualvm first, and then tomcat, solved the problem.
