JAXB and REST Response

[wsdev <st...@daskam.com>]

Hi,

I'm creating a RESTful service with CXF that creates a resource when the
user POSTs some XML. The service works fine when the XML is valid, but when
I send some bad XML, JAXB can't convert it to my java bean and sends back a
500 Internal Server error. How can I make it so that if bad XML is sent to
my service, I capture it and send back a 400 Bad Request response.

Any help is greatly appreciated!!

Thanks,
Steve

I've added a couple of properties to AbstractJAXBProvider, for the output
validation be enabled as well.

You need to have a schema location set on JAXBElementProvider. Next, if a
'validateOutput' boolean property is set then Marshaller will validate using
the schema and possibly a registered ValidationEvenetHandler. If a
'validateBeforeWrite' property is also set then Marshaller will validate
first and write only if the validation succeeds

Will work for JSON too.

I'll update the docs.

What you can do right now is to extend JAXBElementProvider and override its
createMarshaller method and set a Schema instance on it (which is
initialized by JAXBElementProvider)...

thanks, Sergey

Hi

Do you mean you'd like to prevent malformed XML being sent back, in case
when JAXB failed to finish the serializaton process ? The only option here
is to cash the response, use an "enableBuffering' and 'enableStreaming'
properties, see

http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-ConfiguringJAXBprovider

thanks, Sergey
