I think most GlassFish users choose to use the built in JPA
implementation so that they can just use it without having to add
dependencies and configuration to their project. I've only ever
replaced the default implementation (TopLink Essentials) with Hibernate
JPA implementation when needing features not offered by JPA spec or
TopLink Essentials such as criteria API. That is coming in JPA 2.0.
TopLink Essentials is a striped down version of Oracle's TopLink
product. Recently Oracle has donated the full TopLink product to the
Eclipse Foundation and renamed it to Eclipse Link. Eclipse Link is the
reference implementation of JPA 2.0 and will be built into GlassFish
V3. I'm pretty sure it can do everything Hibernate does, and the
original Oracle TopLink was Gavin's source of inspiration when creating
Hibernate.
