How to go for File Caching instead of memory caching

Hi JCS Gurus,

    My tomcat is throwing OutOfMemoryException.  How should I implement
cache for File Caching and not memory caching.  Please suggest.

    My cache.ccf is as below.

# Registry used to register and provide the
# IRemoteCacheService service.
registry.host=localhost
registry.port=1102
# call back port to local caches.
remote.cache.service.port=1102

remote.cluster.AllowClusterGet=true
