Thanks a lot for the answer,
Since I am finsihng up the plug in for openjpa - I am also doing the
QueryCache using Coherence - which is why I asked the question.
We were using kodo here but run into issues - the kodo plugin was not
powerful enough (not was it functional really).
Anyhow - this is why we are looking at opnejpa (and hibernate as well - but
I like OpenJPA better for now - specially since I saw that the StroeManager
code was using the named cache concept properly).
This is why I wrote the new OpenJPA plug in for Coherence.
PS: Would you guys be interested in a Coherence plugin for openjpa? I mean
I could contribute the code.

Yes, that's correct.
Note that Kodo ships with a Coherence plug-in for both data and query
caching.
