J2XB是一个数据绑定框架，拥有处理绑定生成从Java到XML Schema和从Java到SWDL能力，帮助开发者写纯粹Java代码，从数据绑定过程定义，XML Schema/ WSDL生成(使用Axis2模块的WSDL)，无需代码生成器和写任何配置文件。
J2XB Axis2集成属性：
1。Java 到 创建WSDL类型的web service
2。对WSDL类型完整控制，使用J2XB annotations - XML Constraints, Validations, Facets, Substitution Groups等
3。POJO对象发布，同时包括web service的属性函数，支持属性包括：
a）任何J2XB映射bean
b）任何J2XB支持的基本类型或者值对象
c）任何集合(Array, List or Set)
d）函数异常
J2XB属性：
1。从Java代码完整生成XML Schema，包括Schema属性。
o XML validations (Facets, such as minLength and
patterns).
o Substitution Groups
o Full control of the XML document structure, including flattening Java structures and introducing grouping XML elements.
o Support all XML Simple types
o XML Union Types
o XML List Types
2。绑定任何Java对象到XML
o No requirement for inheriting from a common ancestor.
o No requirement to implement any interface.
o No requirement to have a default constructor.
o No requirement to even have a public constructor, if a factory is provided
o Full support for factories (static factories, instance factories)
o Support for Java built in collection types (Set, List, Array)
3。完整支持集成
o Mapped as Substitution Groups
o Complete and accurate XML Schema generation of the Substitution Groups
o Mapping of generic atomic properties (of type Object and Number) to XML Unions.
4。完整XML解析隔离
