JiBX JiBX is a full databinding framework that actually provides not only WSDL-to-Java conversion, as covered in this document, but also Java-to-XML conversion. In some ways, JiBX provides the best of both worlds. JiBX is extremely flexible, enabling you to choose the classes that represent your entities, but it can be complicated to set up. On the other hand, once it is set up, actually using the generated code is as easy as using ADB. In the end, for simple structures, ADB will likely be enough for you. If, on the other hand, you need more power or flexibility, whether you choose XMLBeans or JiBX depends on how much power or flexibility you need and your tolerance for complexity.
