Getting VisualGC to run with VisualVM and TomEE
----------------------------------------------------------------------
VisualGC is a VisualVM plugin - So unless you actually require it, just
ignore this post.
To cut a long story short - VisualGC will not work on a Windows Service,
so don't lose too much time trying.
When I refer to the [JDK] I mean [The full path to the same or better
JDK version as TomEE uses]
VisualGC requires that the JDK tool 'jstatd' is running prior to
starting VisualVM, to do this we need a policy file. Here are the steps:
Create a file called 'tools.policy' somewhere you have unrestricted
access to, then add the following to it and save it (Obviously changing
the path to your own JDK):
grant codebase "file:[JDK]/lib/tools.jar" {
permission java.security.AllPermission;
};
Run jstatd, specifying the path to the policy file and the RMI host
(create a batch file to make this easy):
"[JDK]\bin\jstatd.exe" -J-Djava.security.policy="[Full path
to]/tools.policy" -J-Djava.rmi.server.hostname=127.0.0.1
Now stop any TomEE service that may be running.
Add the following line to the beginning of the '[TomEE]/bin/startup.bat'
file
set "CATALINA_OPTS=-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=9090
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Djava.rmi.server.hostname=127.0.0.1"
Run the '[TomEE]/bin/startup.bat' file (as an administrator if possible)
Now after you start VisualVM you should see two 'Tomcat' listings,
choosing the non-JMX one is preferable.

PS. I'll create a blog for this later.
