JAXB vs XMLBeans

Both are JAVA to XML mapping tools.

Both XMLBeans and JAXB produce Java models that make it easy for developers to interact with XML.  XMLBeans produces a set of Java interfaces that are backed by implementation classes. The JAXB model however is annotated POJOs which has the following advantages:

• JPA annotations could easily be applied to the JAXB model enabling the model to be persisted in a relational database.
• Once generated the JAXB model could be modified to handle changes in the XML schema, the XMLBeans model would need to be regenerated.
• Starting with Java SE 6 no additional compile/runtime dependencies are required for the JAXB model. 
• There are multiple JAXB implementations available:  EclipseLink MOXy, Metro, Apache JaxMe, etc.
• JAXB is the standard binding layer for JAX-WS (SOAP) and JAX-RS (RESTful) Web Services
