The 10.1.3.1.0 release of JDeveloper just hit OTN. You can download it at http://www.oracle.com/technology/software/products/jdev/index.html. The most spectacular changes in this releases are the built in support for the SOA Suite: ESB modeling and deployment and BPEL Process Design, Test and Deployment. This version adds many other new features including a new look and feel, a greatly improved
coding environment with extensive refactoring options, support for the latest
Java standards (J2SE 5.0, J2EE 1.4, EJB 3.0), and visual JSF development. A
visual and declarative approach and the improved Oracle Application Development
Framework (Oracle ADF) work together to simplify application development and
reduce mundane coding tasks, offering developers unparalleled productivity regardless
of their choice of technology stacks and deployment platforms.
Oracle JDeveloper (10.1.3.1.0) extends the IDE features from the previous release
by adding integrated SOA development tools to provide an Integrated Service
Environment workbench. In particular, BPEL (Business Process Execution Language)
and ESB (Enterprise Service Bus) tooling is now fully integrated into JDeveloper.
In addition, JDeveloper’s core IDE features for EJB 3 and JPA (Java Persistence
API) have been extended, and made fully up to date with the final EJB 3 specification.
Working with EJB 3.0 JPA (Java Persistence API) in JDeveloper 10.1.3.1 is
a treat: a wizard to create fully annotated Entities from database tables and views, code coach within annotations, generation and synchronization of the persistence.xml file (for SE deployment and stand-alone testing) and more. Most of what the Dali Eclipse plugin has to offer is here as well (maybe even using the same code base, as Oracle played a major part in creating the Dali plugin.
By the way: The latest JHeadstart build (Service Update 1, Build 97) is also certified against the 10.1.3.1 release of JDeveloper.
