JPA specification does not mandate a JVM-wide or EntityManagerFactory-level cache. But OpenJPA implementation does provide EntityManagerFactory-level cache. It is referred as DataCache and is well-documented in the user guide. This L2 data cache is configurable, it is accessible from user application via OpenJPA-specific extended interfaces and also support synchronization with other EntityManagerFactory-level caches via different communication protocols such as TCP/IP, JMS etc.
