Several major bugs have been fixed, including a major oversight in the XML-RPC implementation having to do with structure marshalling. A basic Registry has been implemented. A Describer based on a simple description language called SWSS has been implemented. Still no SOAP implementation, but it is in the works.
The most immediate thing you'll notice about this release is that Project Labrador now exists in the org.notdotnet.labrador package. NotDotNet is going to be a larger effort to produce a simple, open source web services technology based on Java, and not affiliated with any major corporation (like Sun or Microsoft). JavaDoc and other documentation have also been filled out a little more.
Labrador is an open source modular Web Services Framework. Its purpose is to allow objects to be exposed as Web Services using a variety of protocols, such as SOAP, and XML-RPC.
This version introduces several improvements in the type system and the APIs. Also, several bugs have been fixed, and the API has been documented quite a bit more using JavaDoc.
The 0.2 version of the Labrador XML Object Broker introduces better type conversions, better array support, lots of bug fixes, and an internal HTTP Server. Still no SOAP support, but it should be ready by version 0.5. Also, still no DateTime support, which you can expect in 0.3.
Labrador is an open source modular XML object request broker. It does not attempt to provide full-featured toolkit-style implementations of the protocols that it supports, but attempts to be a simple, and easily configured XML Object broker that allows multiple protocol handlers, instance handlers, and service models.
