Azadeh Ahadian of IBM has published an article introducing JLINQ on IBM's developerWorks site. Despite the name, JLINQ does not have much in common with Microsoft's LINQ, rather it is an Eclipse plugin providing integration with a database and runtime DAO code generation. The plugin is part of IBM's Developer Workbench that is coming with Viper, the next release of DB2.
The ActiveHibernate project brings Hibernate features to JRuby - for those tricky ORM use cases that go beyond what ActiveRecord offers. We talked to project maintainer Johan Andries.
Gavin Terrill explores one of the lessor known facilities available to web developers, the humble "ETag Response Header", and how to integrate its use in a Spring and Hibernate based web app to improve application performance and scalability.
The second beta of the new Hibernate Search project was recently released. InfoQ spoke to project lead Emmanuel Bernard to find out more. The Hibernate Search project is aimed at users of Hibernate or JPA that want to make their Hibernate/JPA-managed objects accessible via indexed, full-text search.
Jetbrains recently released a preview release of IntelliJ 7. Key features include Hibernate, Spring, and Clearcase support.
Three new top level Hibernate projects were released today: Validator, Search, and Shards. Search and Validator are both promotions of existing work. Shards which was contributed by Google is a horizontal partitioning solution built on top of Hibernate Core.
In the latest video interview, EJB 3 co-spec lead Mike Keith discusses the current state of EJB 3, including common praises and criticisms that have been received. He also talks about POJO support and how the spec has evolved towards dependency injection.
A new article on OnJava.com takes a look at configuring Hibernate via annotations. Traditionally developers have either configured Hibernate with XML files separate from Java classes or with XDoclet comments in the Java code with in turn generate XML.
Hibernate team member Emmanuel Bernard recently wrote on the issues with the ActiveRecord pattern and statically typed languages like Java.
One of the common misconceptions about Object/Relational Mapping (O/R Mapping) frameworks is that they give developers caching for free and that caching improves performance. While O/R Mapping frameworks do rely on caching, improved performance isn't in the cards.
A lightweight approach with a rich domain model used directly in web-tier can increase both quality and speed of development. This case study, recorded at Javapolis 2005, looks at a Tapestry+Spring+Hibernate project by Nordija, how it was architected, how testability was introduced, and the level of simplicity achieved using the lightweight approach.
Rick Hightower has posted a few graphs from Indeed's Job Trends comparing Spring against EJB3 and various ORM tools against each other. The graphs show that Spring is steadily gaining while EJB3 (and EJB overall) is not. Similarly, Hibernate continues to dominate the ORM field in job postings.
The Hibernate team has released Hibernate 3.2 GA. This release is ready for production use and includes final releases of the Java Persistence provider, Hibernate Annotations and Hibernate EntityManager. The Hibernate Java Persistence provider has been certified with the Sun TCK.
A heated debate started a few weeks ago initiated by members of the Hibernate team, arguing that using an abstraction framework on top of an ORM is a bad idea, citing Spring's HibernateTemplate as a specific example. Along the theme of levels of abstraction, Brian McCalister also surveyed various convenience frameworks over JDBC.
Firestar Software has filed a patent claim against Red Hat for Hibernate 3 allegedly infringing on a patent covering O/R mapping. Firestar, who has not released it's ObjectSpark O/R product since 2003 claims that it "has suffered and will continue to suffer substantial damages."
