In Relation To

At flush-time, Hibernate needs to know what entity state has become dirty (changed) so that it knows what data needs to be written to the database and what data does not. Historically Hibernate only defined one means of such dirtiness checking, but has since added multiple additional schemes which seem to be not as well known. The intent for this blog is to start a base for improving the documentation around dirty checking and these various options.

The Hibernate team is pleased to announce today's release of Hibernate 4.3.0.Beta1 which targets the (still not finalized) JPA 2.1 specification which is part of the upcoming Java EE 7 platform. This is the first release targeting JPA 2.1 support. As mentioned, JPA 2.1 is not completely finalized so this support should be considered a preview. JPA 2.1 defines a number of enhancements. I won't go in depth in each of them here as I plan to follow up with separate in-depth blog posts for some of these features. However, the web abounds with good summaries of the new features; for example:

The soon-to-be final JPA 2.1 specification adds standardized support for dealing with JDBC CallableStatements (stored procedure and function calls). Arun Gupta has a decent summary of the initial JPA 2.1 features, including Stored procedure support, at https://blogs.oracle.com/arungupta/entry/jpa_2_1_early_draft. Standardized here means both across providers as well as across database vendors. Pretty sweet. As much as I liked the idea of standarized support for handling callable statements, I was not overly thrilled with certain aspects of the proposed JPA StoredProcedureQuery API. My worries were mainly around how the outputs were accessed, especially when multiple results are expected. Let's first look at a simple example of a procedure returning a result:

Bean Validation, Hibernate Validator (its Reference Implementation) and the Test Compatibility Kit have been handed over to the JCP for what is called the Final Approval Ballot. That's when the expert committee votes for the go / no-go of the specification going final as it is.

Hibernate ORM 4.2.0.Final and 4.1.11.Final were just released. The full changelogs can be viewed here: 4.2.0.Final and 4.1.11.Final

With the endgame for Bean Validation 1.1 in full swing, we want to make sure that everyone has the chance to test and integrate early. So without further ado:

I'm very pleased to announce the first alpha release of PicketLink 3.0. This release is the culmination of many months of effort by the JBoss Security team, with many contributions made from other project teams at JBoss and members of the community. I'd like to thank everyone involved with this release, from those who participated in the many design discussions on the security mailing list over the last few months, to those who contributed code and have started integrating PicketLink into their own projects.
