Hi All,
I was just learning 'bt Mbeans. To begin with, I was learning to use and
test the Mbeans that are already existing in tomcat so I get to know how
Mbeans work. I have written my own Agent called UserManager to call the
Mbeans to list users (Tomcat Admin functionality : based on classes
ApplicationServlet, UserUtils and ListUserServlet of tomcat source). I'm
just not able to get a handle to the correct Mbean server. Can I get a
handle to tomcat mbean server at all if I have to use it else where?? I'm
getting the below exception. Kindly let me know how do I get a handle to the
Mbean server from outside the Admin Application. I've used the same
parameters as used by the Admin application classes. I'm using tomcat
5.0.25. Please tell me how to get a reference / handle to the Mbean server.
