Castor should generate public getters/setters (accessor methods) to
obtain
the data. A mapping file can be used.
The biggest problem when trying to use Castor-XML's source code
generator with Castor-JDO is for enumerated types. The source generator
will create type-safe enumerations, that do not have a public
constructor. The trick is to use a custom FieldHandler. I have
demonstrated how to do this in the past on the this list.
If you are not using XML Schema enumerations, then you should be able to
map the object model cleanly.
You can also use the org.exolab.castor.tools.MappingTool to help with
the initial mapping. You'll have to add <sql> elements on your own
however.
