The source of the configuration was classpath.

The diskStore path for this CacheManager will be set to C:\DOCUME~1\CARLOS~1\CONFIG~1\Temp\ehcache_auto_created_1311122127468.

To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a separate ehcache configuration (ehcache.xml) for each CacheManager instance.
