The Apache XMLBeans project is pleased to announce new releases of XMLBeans. The 2.0.0-beta1 release is a significant improvement from previous release and has been in development for about 10 months. The 1.0.4 release is a maintenance release focused on stability and bug fixes. The 1.0.4-jdk1.3 release is the first release of XMLBeans compatible with JDK 1.3.
Major goals of the 2.0.0-beta1 release:
- source backwards compatible
- improve usability of wildcards, substitution groups, error handling
- a native DOM level 2 API
- integration with Saxon xpath/xquery engine
- performance improvements
- instance to schema and schema to instance tools
I am glad to see this:
The XML Schema Working Group has released updated Working Drafts of XML Schema 1.1: Part 1: Structures and Part 2: Datatypes. Please see the status section of each document for changes since the First Public Working Drafts and from the XML Schema 1.0 language. XML schemas define shared markup vocabularies, the structure of XML documents which use those vocabularies, and provide hooks to associate semantics with them. Visit the XML home page

A new Web Services Description has been released:
The SOAP Service Description Language (SSDL) is a SOAP-centric contract description language for Web Services. SSDL enables developers to publish and share descriptions of the messages and message exchange patterns that a Web Service supports. The SSDL work was developed as a vehicle for exploring ideas in the areas of contract and protocol description, and has now been released to the Web Services community for feedback.
I think that one of the main features of WSDL is its SOAP independence. I don’t think that the services described must tightly-coupled with SOAP. Anyway, is another variant to consider.
The WS-Addressing related specifications have been updated:
The Web Services Addressing Working Group has released three updated Working Drafts. Web Services Addressing - Core enables message transmission through networks that include processing nodes such as endpoint managers, firewalls, and gateways in a transport-neutral manner. WSDL Binding defines how the core specification's properties are described in the Web Services Description Language (WSDL). SOAP Binding defines their association to SOAP messages.
The new WD for XQuery, XPath and XSLT are now available:
The XML Query Working Group and the XSL Working Group have released ten Working Drafts for the XQuery, XPath and XSLT languages. Please see the status section of each document for authorship and change history information. XML Query is an XML-aware programming language that can be optimized to run database-style searches, queries and joins over collections of documents, databases and XML or object repositories. Applications implementing XPath can address the nodes in an XML tree. XSLT 2 allows transformation of XML documents and non-XML data into other documents. Visit the XML home page. (News archive)
ebXML registry 3.0 is now closer of become an OASIS Standard.
The OASIS ebXML Registry Technical Committee has voted to approve its ebXML Registry Version 3.0 specification as a Committee Draft and to advance the draft for public review in preparation for ballot as an OASIS Standard.
The ebXML Registry Version 3.0 release is a package of some forty-four files, including the two prose documents ebXML Registry Information Model (RIM) and ebXML Registry Services and Protocols (RS). XML schemas and WSDL files complete the distribution. The specification uses schema documents conforming to W3C XML Schema, and normative text to describe the syntax and semantics of XML-encoded objects and protocol messages.
The second early draft for EJB 3.0 has been released now its composed of two separated documents one for the persistence and one for the rest.
Some of the main additions are:
- the new callback listener / interceptor architecture
- the separate document dealing with entity beans that will evolve into a complete
- specification out-of-container operation of the entity manager (the persistence engine)
- native SQL queries
- definition of interoperability with legacy EJB 2.1 clients and servers
- complete specification of the semantics of association mappings
- complete specification of the semantics of EJBQL
You can find the specification here…
IBM Web Services developer center has published a new article that covers WS-* specifications. This time, Doug Davis covers some aspects of WS-ReliableMessaging and WS-Realiability.
The Architecture developer center has published a new article of Simon Guest. Again Simon talks about Web Services interoperability but now in the mainframe environments using NEON Systems ServiceBuilder
