Description of problem:
The discovery process for Tomcat 6 fails and the resource is always down.

How reproducible:
Every time.

Steps to Reproduce:
1. Start a Tomcat 6 instance (used 6.0.32)
2. Attempt to inventory it.
3. Observe results
  
Actual results:
None of the server child resources are discovered and Tomcat 6 is always down. 

Expected results:
The inventory process works like Tomcat 5 and all the children (eg. webapps) are inventoried.

Additional info:
The following error message is displayed in the logs:
2011-11-30 17:56:15,146 INFO  [ResourceContainer.invoker.daemon-40] (org.mc4j.ems.connection.ConnectionFactory)- Connection library dependancy [catalina-cluster.jar] not found  in directory: /home/snegrea/Downloads/jboss-ews-1.0/tomcat6
2011-11-30 17:56:15,150 INFO  [ResourceContainer.invoker.daemon-40] (org.mc4j.ems.connection.ConnectionFactory)- Connection library dependancy [catalina-optional.jar] not found  in directory: /home/snegrea/Downloads/jboss-ews-1.0/tomcat6

Since those two libraries are Tomcat 5 specific most probably the Tomcat plugin confuses Tomcat 6 with Tomcat 5. I found no other error messages in the logs related to this failure.

The JMX settings have been set correctly in startup.sh prior to starting Tomcat 6.
