One of the nice things about the RI is that you keep on coming across nice little extensions in the com.sun.xml.* tree. Unfortunately many are not even documented so you only find they by reading the daily posts on the jax-ws forum.
Take for example com.sun.xml.ws.developer.SchemaValidation which allows you to validate incoming schemas. Many might say that this is a needless hit and duck typing is fine; but in certain debugging cases it would be nice to have some control over the validation failure process.
By default it uses com.sun.xml.ws.server.DraconianValidationErrorHandler but you can replace this with your own implementation to perform what-ever tracing and debuging you need. Normally you would have any control of this as the service would probably fail before the databinding stage.
@WebService
@ValidationErrorHandler(handler = CustomValidationFailureLogging.class)
public OrderProcessing
{
...
}
Well worth downloading the source code to see what goodies you are missing?

Hi Gerard
In having a look at this feature today, do you agree this is the same as specifying the @SchemaValidation handler with the handler class specified? ie.
@SchemaValidation(handler=MyErrorHandler.class)
I wonder what happens if you specify both?
Do you have any idea in using the @ValidationErrorHandler annotation, what class does the specified handler class need to extend? Presumably com.sun.xml.ws.developer.ValidationErrorHandler?
Cheers,

Ah, in looking at this further the ValidationErrorHandler isn't a valid annotation. So I take it the only approach is to use the @SchemaValidation annotation anyhow.
