First, see 
http://db.apache.org/torque/releases/torque-3.3/runtime/reference/managers-cache.html
for a description on how to use the cache with Torque.

You really should have "torque.useManagers = true" in your Torque 
generator configuration and "torque.manager.useCache = true" in 
Torque.properties.

You could configure a DEBUG logger for org.apache.jcs.

This looks strange to me. Are you sure that the 
org.apache.stratum-package is correct? I'd try org.apache.jcs first.


Bye, Thomas.
