How to open a JMX port in AS 7?

[yairogen]

Hi,

I Can’t find a way to see what is the JMX port used. Where can I find that?

I thought it is not exposed, so I tried to expose it by adding the following to the startup script (like I do for the community hornetq):

-Djava.rmi.server.hostname=127.0.0.1 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=3900 -Dcom.sun.management.jmxremote.authenticate=false

This fails on:

WARNING: Failed to load the specified log manager class org.jboss.logmanager.LogManager

Exception in thread "main" java.lang.ExceptionInInitializerError

Why are you passing these properties? Why you can't just use the JMX Manager provided by AS7?

We need to add/remove topics from a remote application not using the console.

Have a look at the following article: -

https://community.jboss.org/wiki/UsingJconsoleToConnectToJMXOnAS7

Enabling RMI access to JMX is not supported but we provide a library to access JMX over the existing Remoting connections.
