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
