I have implemented an EhCache data and query cache implementation for OpenJPA based on the work of Pinaki Poddar, who created an OpenJPA data cache for Coherence. My code is available on my blog at http://candrews.integralblue.com/2009/03/ehcache-implementation-of-openjpa-caching and is available under the APL 2.0 license.
I think it would be great to have this code included in OpenJPA at some point in the future, and I would be glad to help make that happen. Can someone please review it and help me get it included? Thank you, ~Craig
