public class FKCache
JCACHE implementation of Castor JDO Cache. JCACHE is the Java Temporary Caching API (JSR-107). NOTE: While this cache implementation should work any JCACHE-compliant provider, it is currently intended to work with the FKache open source reference implementation. For more details of JCACHE, see http://www.jcp.org/en/jsr/detail?id=107 For more details of FKCache, see http://jcache.sourceforge.net
