A practical guide to JAXB 2.0
JSR222 specifies the Java Architecture for XML Binding (JAXB) 2.0. JAXB 2.0 specification is implemented in Java Web Services Developer Pack (JWSDP) 2.0. JAXB 2.0 has some new features that facilitate the marshalling and unmarshalling of an XML document. I have used both JAXB 1.0 and JAXB 2.0 and have found that JAXB 2.0 generates less code and has some additional features.
