At work, I’m using Castor XML to Java binding to marshall/unmarshall messages in my Web Services, inside a custom framework (Struts, OJB, JAXM, etc). I have defined my messages as XSD Schemas, and I’m using Castor’s Maven plugin to auto-generate my Java classes at build time.

All is good and well… Hmm, almost! Castor’s SourceGenerator generates Java classes for complex types and elements, but not for simple types, and unfortunately, I badly needed to marshall those simple types as well. But fortunately, I’ve found a little trick to transform simple types to complex types, so that Castor can generate the associated Java classes, with its useful and handy marshall() methods.
