Which one is better for schema to code generation, XMLBeans or JAXB?

Question

Want to use a library for XML schema to code generation and wanted to know if people have a preference between XMLBeans and JAXB. Performance, Schema validation capability, Memory Usage.. Any indicators will help..

Answer 1

My personal preference would be JAXB. It has a more modern approach using annotations and many Java 5 features. XMLBeans on the other hand is still Java 1.4 compliant - if this is required for you. Some other thoughts in no particular oder are:

• From Java 6 on JAXB is bundled with the JDK - so it is available out of the box.
• JAXB works with annotated Java (POJO like) classes - XMLBeans generated interfaces and no classes
• JAXB allows to annotate Java classes to use them for marshalling and unmarshalling or you can start with a XML Schema, generate the Java classes and then fo into un-/marshalling
• XMLBeans allows only to start with a XML Schema, generates interfaces and then use this for un-/marshalling
