Getting keys from JCS Cache

I am using JCS cache for performance enhancement.There is an issue when I need to maintain a set of keys because the type of storage I use is generally offline storage to the disk. Is there a way to get the set of keys alone from the cache as I can with a hashmap,so that I can automate the process of getting the data from the cache,since I dont care about what kind of data comes out of cache because the metadata of the object is stored within the cache object itself.

You can get an array of keys by accessing the MemoryCache of the CompositeCache instance of your cache, this way: CompositeCacheManager.getInstance().getCache(cache_name).getMemoryCache().getKeyArray()

Resolved it myself,

In a group cache access,using putInGroup and getFromGroup there is a method getGroupKeys(groupname),which enables us to get the keys alone from the group within the cache region.The API documentation will greatly help in this case.
