The EJB3 persistence specification calls for implementors to
support Bulk Operations in EJB-QL (the EJB Query Language). As part of Hibernate's implementation of
EJB3 persistence, HQL (the Hibernate Query Language : which is a superset of EJB-QL) needed to support
these Bulk Operations. This support is now code complete, even going beyond what is offered in the EJB3
persistence specification. There is one task outstanding against this bulk operation support in HQL, but
this is completely beyond the scope of the support called for in the EJB3 persistence specification.
I'll blog about this one later as it simply rocks ;)
The first edition of Hibernate in Action has spread quite successfully. On
training or consulting somewhere on-site I often see people with a copy on their desk.
And it has proven to be invaluable to me (and others at JBoss) bringing a few copies
along every-time. There is simply no better additional training material than a professionally
edited full-length book. The only downside is that it is only covering Hibernate 2.x.
The new updated version of the Hibernate Tools (http://tools.hibernate.org) project includes
significant updates to the Eclipse editors, plugings, and wizards, as
well as a unified and convenient Ant task for integration of the tools
in your regular builds.
New to Hibernate 3.0.1 is the SessionFactory.getCurrentSession() method.
It allows application developers to delegate tracking of current sessions to Hibernate itself.
This is fairly trivial functionality, but stuff just about any user of Hibernate had to implement themselves,
or rely on third party stuff to do for them. Let's take a look at how this is implemented in Hibernate and
how it might be useful.
JBoss, Inc is looking to hire a full-time Hibernate consultant based in the United States to help deliver Hibernate-related onsite consulting and training. We're looking for someone with significant experience building enterprise applications using Hibernate. JBoss knowledge is useful but not essential. Please send resumes to firstname.lastname@example.org.
For several months, Versant, an old-school OODBMS vendor with a collapsing market cap, has been
making any number of false claims about Hibernate in online webinars and sales presentations.
I went so far as to write a blog refuting their claims, but then held back on publishing it
because I thought they didn't deserve the attention. They've now resorted to mass emailings
of a document with many false claims about Hibernate, and we've decided we need to respond for
Hibernate 3.0 is the world's most sophisticated ORXM (Object/Relational/XML Mapping) solution. Hibernate3 makes it easier than ever before for Java applications to interact with persistent data, allowing a single definition of the transformation between various in-memory representations of the entity data and the relational schema, even in the case of very complex legacy schemas and schemas for historical data or data with visibility rules. Hibernate3 also provides the most comprehensive object/relational query functionality, with three full-featured query facilities: Hibernate Query Language, the newly enhanced Hibernate Criteria Query API, and enhanced support for queries expressed in the native SQL dialect of the database.
