JAXB Schema validation

Hi ,

I do have  couple of questions.


1)      How to do schema validation while using JAXB with WINK?  My   resource method accepts a JAXBElement which is generated from a schema.  Wink runtime seems to be accepting and marshalling it to JAXBElement even if the element  doesn't have some  required element.

a.       Is  there any other way to do the validation other than declaring the resource method to take a string parameter and doing the marshalling/unmarshalling manually.



2)      In the wink  examples folder under core/jaxb, what is the use of JAXBContext resolver and why don't we have contex resolver for "Phone.class"


Thanks,
Haneef

Hi Haneef,

1)  Currently there is no schema validation.  Although you've pointed
out that it might be desirable to do so.  Can you open a Jira for this
so we can explore it?
    a.  That's the only way to do it, currently.

2)  Wink has a default context resolver that configures the JAXB
context to include only the class currently being marshalled.  If the
JAXB object hierarchy is significantly more complex than this, it may
be necessary to construct your own JAXB context by way of implementing
a custom ContextResolver.  The Javadoc in JaxbResource has an
explanation.  Those resolvers for Person and Address do the very same
thing the default Wink context resolver does for Phone.  It's an
example of what you *could* do, not necessarily what you *should* do.
:)
