is there any way to run java class without client invocation in tomcat?

Hello all
i wander if there is possibility to invoke java class from tomcat server say for instance
when tomcat is done loading he will invoke some kind of class that prints "hello ..."
to the prompt , whiteout invoking it from the client side (like jsp page calling java class ).
thanks

the "prompt"? What's that?

I suppose (but have never tried it) you could set up a servlet to load at server startup and have that servlet spawn a process on the server machine that would pop up a window on the console to print the message or somesuch... but I'm not quite sure why you'd want to do that in the first place, really.

Is that what you're inquiring about?

Create a class that implements ServletContextListener and configure it in the deployment descriptor.

When you say prompt do you mean the app server log?

hello and thanks for the fast reply
yeah i mean to the server log or othere log ,
i like to invoke thread deamon when the server starting
so you say servelet?

ContextListeners are probably what you're looking for:
