Hi, It's all about WS. We have at the backside domain model implemented on java. We also have the same model in xml schema. It's so easy to use once implemented schemas and java code together.
So we have some set of web services witch requires of course xml schemas. When schemas are standard, then them reuse is simple. We are currently using Axis2 for WS implementation. The problem is generated code, wich smells and also generates again and again same classes for different services. So we want to move to the next level. Seems that spring ws + castor is right solution. No any more generated code but simple nice code. The other side why not generate xml schemas from code or backward are other standard schemas that are not in our hands. Those are for example SAML, SPML, ... They has own implementations and stanardiseded schemas and there is no way or reason why we event think to generate something.

Why don't you generate the Java classes (and the corresponding descriptor classes) from the XML schema (using the XML code generator) and let Castor take care of the rest ? I have never understood why somebody would want to use a mapping file when there's an XML schema available.
