JAXB 2.0 and JAX-RPC 2.0 EA specs are out

The EA versions of JAX-RPC 2.0 and JAXB 2.0 specs are now available. These are early access releases, consistent with the latest JCP process that is encouraging early feedback on the specifications from the wider community, which I think is a good thing(tm).

Check the specs out. As an EA, there are some relatively big holes in the specs; for example, the JAXB 2.0 spec is only hinting at the addition of updateable partial binding, which I think is a very big improvement. There are a number of other key improvements, including:

• Integration of the two specifications: you now will be able to use the full JAXB machinery to do data-binding on JAX-RPC invocations
• Completion of much of the customization features in JAXB that were hinted in JAXB 1.0.
• Updateable partial binding, where a portion of an XML document can be bound to Java objects, which can then be updated and then converted back to a document.
• Support for asynchronous messaging in JAX-RPC.
• Support for other transports to HTTP in JAX-RPC.

There are other features; attend the JavaOne sessions on these topics to get more details, and I'l invite Marc, Roberto, Sekhar and Joe to present at some technical forum in the near future.
