EclipseLink @ DZone Refcard
By alexismp on May 30, 2011
From intro (did you know that EclipseLink was the reference implementation for SDO or that EclipseLink ships as a single JAR file?) to Maven, OSGi, Weaving in JavaSE,
eclipse-orm.xml, fetch groups, cache configuration and much more, it's amazing how much great stuff Gordon was able to cover in this short document.
Keep an eye on the GlassFish Podcast later this week for an episode featuring a discussion with Doug Clarke on EclipseLink.
