send commands to a webapp running on tomcat

Question

I'm new with java and tomcat, so, excuse me if it's silly.

I would like to send commands (from the console) to a servlet that is already running on tomcat. The webapp will run the command in the tomcat context and return the appropiate answer.

ie:

$ consoleApp status
running

Is it possible?, if yes, how?

thanks in advance.
