Layout of OpenJPA installation has changed since I last blogged about using OpenJPA in GlassFish. Let's say one installs OpenJPA in a directory called ${OPENJPA_HOME}. Earlier (I am talking about the days when OpenJPA was still in Apache incubator), all the jars would live under ${OPENJPA_HOME}/lib directory. Now, things have changed. The primary artifact, openjpa-${version}.jar, which contains classes built out of OpenJPA codebase lives under ${OPENJPA_HOME}; where as all the other library jars live under ${OPENJPA_HOME}/lib. So, all you need to do is to copy the appropriate jars like this:

 cp ${OPENJPA_HOME}/openjpa*.jar ${OPENJPA_HOME}/lib/*.jar ${GLASSFISH_HOME}/domains/domain1/lib 

and restart GlassFish. For further information, please refer to my earlier blog. I have updated that blog as well.

For issues, please don't hesitate to contact us at users (at) glassfish.dev.java.net
