Let me give a little background....i have a client passing XML to my JAX-RS
service. I am using JAXB bindings. I appended some extra characters to the
XML which i sent the service to see how it would error, in particular what
the client would get as a response. The client got a JAXBException of some
sort...can not remember from yesterday afternoon ;).
If i register an ExceptionMapper for JAXBException or any of the XML
Validation exceptions i see, would that allow me to make a custom error
message to send back to the caller?
Yes, sure. JAXBExceptions are wrapped into WebApplicationExceptions but you can get to the cause exception, you need to register
ExceptionMapper<WebApplicationException>. Alternatively, you might want to register a ValidationEventHandler instance with
JAXBElementProvider and when it's notified of the validation issues you can then throw some custom CustomValidationException and
register ExceptionMapper<CustomValidationException>, you can register ValidationEventHandler as a 'validationEventHandler' property
on org.apache.cxf.jaxrs.providers.JAXBElementProvider.
Does it help ?

Hi,
You can register an exception mapper as a provider from Spring, inside a
jaxrs:providers tag.
As far as the validation is concerned, here is how you can do it :
http://cwiki.apache.org/CXF20DOC/jax-rs.html#JAX-RS-Schemavalidationsupport
You can also inject an instance of ValidationEventHandler into a JAXB
provider.
Or you can get more control by registering a custom XMLStreamReader and
do
some schematron-like validation in there...and throw some exception from
there....Let me know please if you'd like some more info on this last
option.
cheers, Sergey

Subject: JAX-RS Exception Handlers and Validation
I am looking at how to get validations and exception handling going.
Right
now i send some garbage XML in and it throws a JAXException back in the
response. I would prefer to be able to handle this back on the serve
and
give the client a less specific error.
I am using Spring to configure things and i did not see anything in the
examples which shows me how to add an exception handler or how to get
control of the XML Validations. Can anyone point me in the right
direction?
