App runs on JVM which doesn't support attach mechanism

Postby niemar » Fri Oct 20, 2017 11:11 am

I am trying to profile my webapp which runs inside a tomcat server. I have followed all procedures in configuring my profiler to work. but i always end up with the same issue. Attach is not supported by the JVM.
Here is a log file generated:

What is the exact error message?

Anyway, if the attach approach doesn't work, start Tomcat with the profiler agent instead.
