Usage of Object Cache for Java in J2EE apps

Question

Hi,
we are investigating on whether we can use the Object Cache for Java
(OCS4J) for our requirements. The question we have come across is:
What is the designated way of integration for the Object cache to fit
into the J2EE environment? Unfortunately, although the current manuals
group OCS4J into the "Oracle Containers for J2EE Services Guide" and the
suggested package name for the whole thing in JSR 107 seems to be
javax.util.jcache, there is very little documentation on how the
designers would like J2EE programmers to use the cache from within a
J2EE app and all examples given are not from within a J2EE environment.
We are in particular thinking about a hierarchy of several cache
"compartments" (Region->Subregion->group) for different topics and using
the hierarchical name of the cache (region.subregion.group) as the
primary key for BMP Entity beans, each of them having their own
CacheAccess object. Then we would have an API of stateless Session beans
on top of that, which would be determining the cache "compartment", get
the appropriate Entity Bean with the Cache Access object and then do the
required operations on the cache.
But then we immediately run into the question of how the mapping between
Cache Objects and CacheAccess objects will be done etc.
So is there anybody that can give us any hints how to use the OCS4J in
an EJB scenario?
Thanks in advance for any help!

Answer 1

We have Java client requesting over HTTP to application server. We would like to cache some of the objects created by the servlet while serving the request. Can I use the OCS4J for caching the Java objects. Do I require any software or just copying the JAR file and importing the class would serve the purpose?
