Geronimo has a secure JMX server embedded. However, the JMX server is not started by default. To start the secure JMX server, start the org.apache.geronimo.framework/jmx-security//car module using the Admin Console or the deployer tool. For example:
<geronimo_home>/bin/deploy -u system -p manager start jmx-security
The secure JMX server will be running on port 9998.
The deployer tool, the GShell deployer commands, and other command line tools can be configured to use the secure JMX server. Please see Tools and commands for more information.
