I've been on the commons and the turbine lists discussing my conversion of a working caching system into something closer to the osc4j cache ( an element attribute driven model ).
I needed a repository so I put the cache project on sourceforge.
I'm still working on it. But you can see how it is progressing at:
http://sourceforge.net/projects/jpolycache/
http://sourceforge.net/project/showfiles.php?group_id=22271
I made the auxiliary caches pluggable, like log4j appenders. See the cache.ccf file in the props directory. I'll explain how an auxiliary can be created in the documentation, that I'll write soon.
Though I don't the osc4j lateral model is wise, I've created a working tcp lateral distribution system, and made a udp sprayer as an exercise. They both implement the Zombie pattern ( a balking facade ) we developed for the remote cache to prevent blocking and allow for undisruptive resource recovery.
The remote cache is working nicely. I need to put in a read lock for group attribute removal and it should be functionally complete.
Next I'm going to make the disk writing occur in the background with a temporary memory buffer.
Then, I'm going to make the memory management section pluggable so someone can develop another cache hub and alternate memory management algorithms (right now it is lru in a double-linked list).
Then, I'll make a remote hot standby.
Yes, I could use some help.
I had something stable but it wasn't configurable enough, so I've been making major changes. . . .
Let me know what you think.

Thanks for that Ellis.
I'm on the JSR as are a few other Jakarta Commons people I think.
Certainly I'd like to keep the Jakarta Commons cache project quite JCache
friendly, using similar terminology, APIs and ideas. As yet there is no
comment on if there will ever be an official, open source JCache
implementation so maybe Jakarta-commons cache might one day become one.
