Service Classpath

I wrote a couple of Axis2 Web Services using Eclipse and both seem to work fine.  I am working on a larger web service that requires a couple of jar files to the included on the classpath.  I placed the jar files in the Axis2 lib folder and that works, but I would like to keep the jar files in a location specific to the service.

The Axis2 Service Archiver allows the user to add jar files to the lib folder in the aar file.  How do I add those jar files to the classpath of that service?
