Java^TM Architecture for XML Binding
2.0 CHANGELOG

The JAXB 2.0 RI is a major reimplementation to meet the requirements of the 2.0 specification.

Please refer to the JAXB 1.0.x changelog for older releases.

Notable Changes between 2.0 Early Access 2 and 2.0 Early Access 3

• Map property can be now correctly bound to XML Schema
• Default marshaller error handling behavior became draconian (previously errors were ignored.)
• @link to a parameterized type is now correctly generated
• started producing architecture document for those who want to build plugins or play with the RI internal.
• XJC now uses the platform default proxy setting by default.
• @XmlAccessorOrder, @XmlSchemaType and @XmlInlineBinaryData are implemented
• @XmlJavaTypeAdapter on a class/package is implemented
• Marshaller life-cycle events are implemented
• Integration to FastInfoset is improved in terms of performance
• XJC can generate @Generated
• The unmarshaller is significantly rewritten for better performance
• Added schemagen tool and its Ant task
• Various improvements in error reporting during unmarshalling/marshalling
• JAXB RI is now under CDDL

Notable Changes between 2.0 Early Access and 2.0 Early Access 2

• The default for @XmlAccessorType was changed to PUBLIC_MEMBER
• Optimized binary data handling enabled by callbacks in package javax.xml.bind.attachment. Standards supported include MTOM/XOP and WS-I AP 1.0 ref:swaRef.
• Unmarshal/marshal support of element defaulting
• Improved the quality of the generated Java code
• Fixed bugs in default value handling
• Runtime performance improvements, memory usage improvements
• Added support for <xjc:superInterface> vendor extension
• Migrated source code to http://jaxb2-sources.dev.java.net
• Published NetBeans project file for JAXB RI
• Added more support to the schema generator: anonymous complex types, attribute refs, ID/IDREF, etc
• Implemented javax.xml.bind.Binder support (not 100% done yet)
• Implemented marshal-time validation
• Improved xjc command line interface - better support for proxy options, more options for specifying schema files
• Added schema-2-Java support for simple type substitution
• Added support for the new <jaxb:globalBindings localScoping="nested" | "toplevel"> customization which helps control deeply nested classes
• Made the default ValidationEventHandler more forgiving in 2.0 than it was in 1.0 (The class still behaves the same as it did when used by a 1.0 app)
• Added wildcard support for DTD
• Numerous other small changes and bugfixes....

Notable Changes between 1.0.x FCS and 2.0 Early Access

• Support for 100% W3C XML Schema (not all in EA, but planned for FCS)
• Support for binding Java to XML
• Addition of javax.xml.bind.annotation package for controling the binding from Java to XML
• Significant reduction in the number of generated schema-derived classes
  • Per complex type definition, generate one value class instead of an interface and implementation class.
  • Per global element declaration, generate a factory method instead of generating a schema-derived interface and implementation class.
• Replaced the validation capabilities in 1.0 with JAXP 1.3 validation API's
• Smaller runtime libraries
• Numerous other changes...
