Schema validation for one-way web service operation

[dfilippov]

Hello!

I have a JAX-WS web service with one-way operation and I use CXF's @SchemaValidation in order to validate inbound messages against schema specified in WSDL:

@WebService
@org.apache.cxf.annotations.SchemaValidation
public class Foo {
    @WebMethod
    @Oneway
    void bar(Baz baz) {
       ...
   }
}

Everything works great for regular (synchronous) operation: CXF validates inbound message and responds with SOAP fault if the message doesn't match the schema.

But for one-way operation (e.g. bar), validation occurs after the server already sent 202 HTTP response and bar isn't called at all in case of validation failure.

Is there any way to make CXF validate messages before sending 202 response to client? Or is there more correct approach to validate inbound messages for one-way operation?

Any help would be appreciated!

I don't think think is possible because the framework will return immediately on connecting to a @Oneway service. I'm not sure if schema validation is the right approach, but perhaps bean validation is something that might work instead? http://cxf.apache.org/docs/validationfeature.html#ValidationFeature-CommonBeanValidation1.1Interceptors

Mustafa, thank you for advice. I'll try to use bean validation.

The main reason why I want to validate inbound messages against schema is that JAXB silently sets null to (for example) Integer field if corresponding XML-field contains invalid data (not a number).
