Seam
We released Seam today.
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 gavin@hibernate.org.
Hibernate 3.0 presentations
I recently spoke at TheServerSideJavaSymposium and at the New England JUG. My presentations, which cover some new ideas implemented in Hibernate 3.0 are now online:
Versant Spam
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 the record.
Hibernate 3.0 released!
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.
EJB 3.0 EDR2
Cedric beat me to this, but if you missed his announcement, the EJB 3.0 second early draft is available. The most interesting new stuff to me is:
Hibernate 3.0 goes beta
We just released Hibernate 3.0 beta 1. I've no time to list all the many changes since the alpha was released four months ago, let alone everything that is new in Hibernate3, which has been in development for over a year now.
Discrimination
Type - not sex, or race - discrimination is what we do when we read a row from a SQL query result set, and determine what Java class we should instantiate to hold the data from that row. Type discrimination is needed by any ORM solution or handwritten persistence layer that supports polymorphic queries or associations.
Hibernate Training in Melbourne
September 20-22 in Melbourne will be the first time we deliver our new three-day Hibernate course. The course has been heavily revised and expanded to include previews of the cool new stuff coming in Hibernate3 and an overview of Hibernate internals (/very/ useful if you ever need to debug a Hibernate application). There are still seats available, if you're quick! This will be the last training we run in Australia for a while, since I won't be in the country much, if at all, over the next six months or so. Email training@jboss.com for more information. (We also have an upcoming course in Paris, November 3-5.)
