Oracle Coherence can be integrated with Hibernate, an object-relational mapping tool for Java environments. The functionality in Oracle Coherence and Hibernate can be combined such that Hibernate can act as the Coherence cache store or Coherence can act as the Hibernate L2 cache.
If you are interested in using Coherence with Hibernate, see the Coherence Hibernate Integration project that is part of the Coherence Community. Coherence Community projects provide example implementations for commonly used design patterns based on Oracle Coherence.
