Jason, When you generate your java classes you will end up with one for the elements in your xsd, and each of those will have a corresponding "Descriptor" class generated. These descriptor classes are used for xml serialization by default, so no extra mapping is needed justt for serialization. An additional mapping is needed if you decide to use JDO for persistence...

An instance of a message type will be manipulated in Java and subsequently needs to be persisted in XML form. A common use case for Castor users I imagine. So I am using the SourceGenerator tool to produce the Java sources but I was wondering what the best way is to create a mapping.xml file. I see the option that will place the marshalling code into the classes but to marshall an instance to XML do I still need the mapping.xml file? If possible, ideally what I would like is to essentially have the generated Java sources just be data storage. Persistence to XML is only one potential location so I would like to keep the Castor specific marshalling functionality outside the generate sources if at all possible. I'm using Betwixt to marshall some less complicated messages and we use TopLink to persist to DBs. So in summary I require: 1. Generation of Java sources from an XSD file. 2. I would like the generated sources to be as lean as possible and essentially be data store and entry point for application development for a particular message type. 3. I would like to generate a mapping.xml file for the generated Java sources. I assume we have a corollary happening here in that if the Java sources are being generated from the XSD file and implicit somewhere is the information that would go into the mapping.xml file. Is that correct? 4. I would like to be able to use the mapping.xml file at run-time to persist the instances. What is the best way to go about satisfying the requirements listed above? The other questions I had are: 1. What exactly are the descriptors that can optionally be included in the sources. 2. Does the MappingTool use these descriptors to produce a mapping.xml file? -- jvz.
