JAXB

JAXB performs transforms between XML schemas and Java classes using...

xjc schema compiler	Create JavaBeans from XML schemas
schemagen schema generator	Create XML schemas from JavaBeans.

JAX-WS leverages the JAXB API. WAS v8.5.5 supports the JAXB 2.2 specification, which is required by JAX-WS 2.2.

XML instance documents can be converted to and from Java objects through the use of the JAXB binding runtime API. We use the resulting Java classes to assemble web services applications.
