Subject [jira] Created: (CXF-1551) validation against XML schema - leads to invalid soap response
Date Sat, 26 Apr 2008 22:52:55 GMT
validation against XML schema - leads to invalid soap response
--------------------------------------------------------------

                 Key: CXF-1551
                 URL: https://issues.apache.org/jira/browse/CXF-1551
             Project: CXF
          Issue Type: Bug
          Components: JAXB Databinding
    Affects Versions: 2.1
            Reporter: jmi


when XML schema validation is enabled, and mandatory element is missing (probably the same
for any other error) in CXF-generated response, then response is invalid in some cases.

E.g. such response is generated from modified wsdl_first sample:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><sayHiResponse
xmlns="http://apache.org/hello_world_soap_http/types"><responseType>Executing operation
sayHi1</responseType><responseType2><responseType>THIS IS IMPORTANT .. VERY
LONG TEXT ..SOMETHING WILL BE flushed probably and that's why cannot be removed later when
fault should replace content ................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................<soap:Fault><faultcode>soap:Server</faultcode><faultstring>Marshalli
ng Error: cvc-complex-type.2.4.a: Invalid content was found starting with element 'responseType2'.
One of '{"http://apache.org/hello_world_soap_http/types":responseType}' is expected.</faultstring></soap:Fault></soap:Body></soap:Envelope>

in attachment you can find  modified sample I used to show the bug in simple enough project.
Just do "ant server" and then invoke sayHi from soapUi or other tool, You should see response
listed above.


Dans comment from mailing list:
Basically, fixing this will require breaking the streaming.  Most likely, 
if validation is turned on, we'll need to buffer the message to a cached 
stream, and if that doesn't result in a error, then flush the buffer to 
the real output stream.  That will be a little bit slower, but would fix 
this issue.
