GlassFish Java Persistence API download bundle
The implementation of the Java Persistence API has been availale in GlassFish for quite some time. Last week the GlassFish team made available separate Java Persistence API standalone bundle. This is useful for users who want to use Java Persistence but don't want to have to use the EJB container.
Previously out-of-container users had to download GlassFish and extract the required jar files. Now all users need to do is to download the implementation of the Java Persistence API bundle, unzip and they are ready to go. The implementation is feature complete though not yet final so expect weekly builds with bug fixes.
The Tech Tips and Blogs page has pointers to several useful articles and blogs on Java Persistence.
