I might be missing something really obvious here, but I couldn't find the sources for a few classes from the javax.persistence package.

I'm using EclipseLink as a JPA provider. When I tried Ctrl+left clicking a method of the EntityManager interface, Eclipse said that I should attach the sources since it can't find them. I tried attaching the EclipseLink ones but it complained it cannot find the source for EntityManager there.

What sources do I need to attach in order to view the code in Eclipse? Could somebody provide a link?

I think if you create a JPA project type in Eclipse you will be able to see the JPA source, or perhaps load the JPA module.

Only the source code to EclipseLink is in the eclipselink-src.jar, you can access the source to JPA from the EclipseLink repository,

http://dev.eclipse.org/svnroot/rt/org.eclipse.persistence/trunk/jpa/plugins/

The source is not that interesting for JPA, as it is a spec, and all interfaces, there is little to no real code.
