Install eclipselink in Glassfish 2.x.x

Installing eclipselink in glassfish is a piece of cake.

First step is to download the eclipselink.jar from :

http://www.eclipse.org/eclipselink/downloads/

Second step is to put ecllipselink.jar (some might also need the persistence.jar) in {glassfish_home}/lib so that the library is available to all domains.

Third step is to create a connection pool. Use the following tutorial for an oracle pool:

And last, deploy your eclipselink application.

If this tutorial is too short for you, tell me what you need me to analyze more.
