OpenJPA Caching Provider
Ehcache easily integrates with the OpenJPA persistence framework.
Installing
To use it, add a Maven dependency for ehcache-openjpa.
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-openjpa</artifactId>
<version>0.1</version>
or download from downloads.
Configuration
Set OpenJPA�s openjpa.QueryCache to ehcache and openjpa.DataCacheManager to ehcache. That�s it!
See http://openjpa.apache.org/builds/1.0.2/apache-openjpa-1.0.2/docs/manual/ref_guide_caching.html for more on caching in OpenJPA.
Default Cache
As with Hibernate, Ehcache's OpenJPA module (from 0.2) uses the defaultCache configured in ehcache.xml to create caches.
For production, we recommend configuring a cache configuration in ehcache.xml for each cache, so that it may be correctly tuned.
