Why use MemCache for database results caching when hibernate and spring does it all

I have been arguing this question with myself, Why does anybody need memcache for caching database results when you have hibernate caching or you can enable any other third party cache.

Let me put it this way. Is memcache different type of cache then EHCache or any other open source caches.

Thanks,

Whatever is used for Hibernate/JPA caching is for DB contents only. Standalone caches can be used for all kinds of data, wherever they originate. In that sense it's not much different from EhCache in standalone mode (outside of JPA). I don't think EhCache can be used by non-Java clients, though.

Why does anybody need memcache for caching database results when you have hibernate caching or you can enable any other third party cache.

I agree with ulf and how can you expect that every project will be built using technologoes Hibernate Or Spring .

Plus, you can have Hibernate use memcached for caching.

Thanks guys !
