I'm using OSCache in two places in my application. In one place, it is being used in code "manually" to cache images. This configuration specified a non-existent directory for the disk cache, which gets created and populated at runtime, very much as I'd expect.

In the other place, I'm using Hibernate EntityManager with OSCache as the second level cache. I'm providing a second properties for this purpose, so I can have seperate control over the caching. To avoid any clashes, I'm specifying an alternate directory.

This directory never gets created, nor populated, even if I turn memory caching off.

The logs indicate that they are using my alternate cache, but the settings don't seem to have any real effect.

If I disable the use of the non-Hibernate cache, the situation remains the same.

Hibernate version: Annotations: 3.3.1GA, EntityManager: 3.3.2GA

hibernate-oscache.properties:
Code:
cache.memory=false
cache.capacity=5
cache.unlimited.disk=true
cache.path=/tmp/foo/hb-cache
cache.persistence.overflow.only=true
cache.use.host.domain.in.key=true


hibernate.cfg.xml:

Notice how the second configuration gets picked up later. Could this be overriding the initial configuration?!
