I'm trying to invoke Catalina Deployer MBean method. The MBean is
created after I embed Tomcat so you can think of it as my own MBean.
Again, although the method is visible but "not operational". Trying to
figure out why and where the MBeanServer is making the method "not
operational".
If you're on swan, you can access my mbean -
http://asengsol1.sfbay.sun.com:8082/ViewObjectRes//Catalina%3Atype%3DDeployer%2Chost%3Dlocalhost
Description of manageApp (Operation Not Supported)
void manageApp (org.apache.catalina.Context)context
manageApp operation is listed but says "Operation Not Supported".
