Something like (and I completely don't know the JAXB API)
public class JaxbFieldValidator extends FieldValidatorSupport {
public void validate(Object object) throws ValidationException {
String fieldName = getFieldName();
String fieldValue = this.getFieldValue(fieldName, object);
// making this up
// associate our adapter class with Jaxb to get the error
messages
Jaxb.setErrorHandler(new JaxbErrorAdapter(fieldName,
getValidatorContext()));
// do the Jaxb mapping to beans - any errors should be
propogated to the ValidatorContext (usually your Action)
Jaxb.doWhatever();
}
/**
* Implement the Jaxb error interface
*/
private class JaxbErrorAdapter implements JaxbErrorHandler {
private String propertyName;
private ValidatorContext context;
JaxbErrorAdapter(String propertyName, ValidatorContext context)
{
this.propertyName = propertyName;
this.context = context;
}
/**
* Implement the JAXB error methods here - this will put them
into the context
*/
addError(String message) {
context.addFieldError(message);
}
}
}
This could all be done in your Action too, and just have it add the
error messages directly with this kind of adapter, or use it in a
validator, etc... Depends on whether you want to use these beans after,
or if you're just checking that the XML is ok...
