First, the collector server is optional: you may monitor your application 
without using the collector server. And deploying the collector server in the 
same tomcat than the application is irrelevant.

Then, the javamelody monitoring must be installed and working in your 
application (http://code.google.com/p/javamelody/wiki/UserGuide), before adding 
it to the collector server.

So, what is displayed if you open http://localhost:8080/xxx/monitoring
in a browser where http://localhost:8080/xxx/ is the url of your application?

No response from the reporter, so resolving as invalid/incomplete.
