Hi all,

I am trying to configure JCS embedded within Apache Torque, which in theory is as simple as creating cache.ccf and placing it in the classpath.

In practice, JCS.getInstance(region) returns null every time, and I have spent the last few hours stabbing in the dark as to why.

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.

- Is there a way that I can receive confirmation that JCS found a cache.ccf file, and if so, where it found the file?

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

- In the /WEB-INF/classes directory of the webapp that wraps the code
This is where I put mine.

jcs.region.com_domain_Signature=
jcs.region.com_domain_Signature.cacheattributes=org.apache.stratum.jcs.engine.CompositeCacheAttributes
jcs.region.com_domain_Signature.cacheattributes.MaxObjects=1200
jcs.region.com_domain_Signature.cacheattributes.MemoryCacheName=org.apache.stratum.jcs.engine.memory.lru.LRUMemoryCache

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.
