> I want to use the same interface and implementation for exposing the SOAP and REST web service through CXF. For JAX-WS I want to use the Namespace Qualified elements in request and response but for JAX-RS I want to ignore the namespaces for both request/response.
> I am using the default Jettison JSON Provider with "ignoreNamespaces" property set as "true". Have a look at my config:
> {color:#205081} *<jaxws:endpoint* id="helloWorld-ws" {color}
> {color:#205081} implementor="*com.nit.ws.service.impl.HelloWorldServiceImpl*" address="/HelloWorldService">{color}
> {color:#205081} <jaxws:inInterceptors>{color}
> {color:#205081} <ref bean="httpAuthHeaderInterceptor" />{color}
> {color:#205081} </jaxws:inInterceptors>{color}
> *{color:#205081}</jaxws:endpoint>{color}*
> {color:#205081} *<jaxrs:server* id="helloWorld-rs" address="/helloWorldService">{color}
> {color:#205081} <jaxrs:serviceBeans>{color}
> {color:#205081} <bean class="*com.nit.ws.service.impl.HelloWorldServiceImpl*" />{color}
> {color:#205081} </jaxrs:serviceBeans>{color}
> {color:#205081}<jaxrs:providers>{color}
> {color:#205081} <ref bean="*jsonProvider*" />{color}
> {color:#205081} </jaxrs:providers>{color}
> {color:#205081} <jaxrs:extensionMappings>{color}
> {color:#205081} <entry key="xml" value="application/xml"/>{color}
> {color:#205081} <entry key="json" value="application/json"/>{color}
> {color:#205081} </jaxrs:extensionMappings>{color}
> *{color:#205081}</jaxrs:server>{color}*
> {color:#205081} <bean id="httpAuthHeaderInterceptor" class="com.nit.ws.security.HttpAuthHeaderInterceptor" />{color}
> {color:#205081}<bean id="*jsonProvider*" class="*com.nit.rs.json.StripNamespaceJsonProvider*">{color}
> {color:#205081} <property name="*ignoreNamespaces*" value="*true*" />{color}
> {color:#205081} </bean>{color}
> The *StripNamespaceJsonProvider* simply extends the default CXF's *JSONProvider* and calls the super class readFrom() and writeTo() methods. Right now it doesn't have any functionality.
> The following is the common *HelloWorldService* interface that I am using for both JAX-WS and JAX-RS:
> *{color:#205081}@WebService{color}*
> {color:#205081}public interface *HelloWorldService* {{color}
> {color:#205081}......{color}
> ......
> {color:#205081} @WebMethod{color}
> {color:#205081} @POST{color}
> {color:#205081} @Path("/sampleRequest"){color}
> {color:#205081} @Consumes(\{MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML}){color}
> {color:#205081} @Produces(\{MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML}){color}
> *{color:#205081}public OperationResponse sampleRequest(@WebParam(name="request") OperationRequest request);{color}*
> {color:#205081} @WebMethod{color}
> {color:#205081} @POST{color}
> {color:#205081} @Path("/sampleResponse"){color}
> {color:#205081} @Consumes(\{MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML}){color}
> {color:#205081} @Produces(\{MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML}){color}
> *{color:#205081}public OperationResponse sampleResponse();{color}*
> {color:#205081}}
>
>
>
> The *sampleResponse()* method works because of "*ignoreNamespaces*" property has been set to "*true*" but not the *sampleRequest(OperationRequest request)* method.
>
> I used the following request JSON to test the *sampleRequest* method using a REST client:
>
> {
> {color:#205081} "operationRequest": {{color}
> {color:#205081} "operationName": "chottukumaru",{color}
> {color:#205081} "payload": "golmamu"{color}
> {color:#205081} }{color}
> {color:#205081}}
>
> However, it throws up the following exception:
>
> {color:#d04437}16-Jul-2018 18:28:40.205 WARNING [http-nio-8080-exec-2] org.apache.cxf.jaxrs.provider.AbstractJAXBProvider.handleExceptionStart javax.xml.bind.UnmarshalException{color}

> {color:#d04437} at org.apache.cxf.jaxrs.utils.JAXRSUtils.readFromMessageBodyReader(JAXRSUtils.java:1354){color}
> *The reason* that I found is that the default *org.apache.cxf.jaxrs.provider.json.JSONProvider* has two methods: *writeTo()* and *readFrom()*. The writeTo() method uses the property "*ignoreNamespaces*" to determine if namespaces have to be ignored while marshalling a Java object to JSON but the readFrom() method doesn't uses the same property to ignore the namespaces while un-marshalling the JSON into a Java object.
> _What approaches do we have to solve this issue? (Not sure if this is even an issue or am I simply unaware of some other configuration)._
> _Do we have this issue for other JSON Providers also like Jackson or Moxy?_
> I am attaching my complete web-project as a ready reference. [^springcxfserver.zip] It can be simply built using maven.
> I am using JDK 1.8.0_144, Apache CXF 3.2.5, Tomcat 8.0.5, and Spring 5.0.4 for this sample project.
