Start/stop application in tc server using JMX/Hyperic agent

Is there a way to start, stop or restart applications running within tcserver using JMX or using a HTTP request? For example, in tomcat 6.0, the following can be done to start an application:

http://localhost:8080/manager/start?path=/examples

When I start the hyperic agent, I could not see any Mbeans defined for the agent process to start/stop a runtime instance within a tcserver.

A Tomcat (and tcserver probably as well) registers a MBean for every WebModule which looks like

Catalina:J2EEApplication=none,J2EEServer=none,j2eeType=WebModule,name=//localhost/jolokia

where the domain name and name property depend on your installation and the WebModule. Each of those MBeans has a start() and a stop() operation.

In case you are using a Jolokia agent, you can directly use an HTTP call like 

  wget -O - -q
      http://localhost:8080/jolokia/exec/Catalina:J2EEApplication=none,J2EEServer=none,j2eeType=WebModule,name=/--/localhost/-/jolokia/start

(slashes needs to be escaped, single slash with /-/, double slash with /--/. See the Jolokia reference manual) for details.
