Re: Camel CXFRS endpoint unable to produce JSON

[Sergey Beryozkin]

Hi Christian,

Thanks for this tip, FYI, CXF will try to use JSON provider (with the 
default configuration) if it has not been explicitly configured 
(example, a namespace map may be not strictly needed, etc). I wonder, if 
in this specific case,
HTTP Accept header is actually set to application/xml, so the fact the 
service can produce JSON is ignored, not really sure though

Cheers, Sergey

You have to tell CXF to use JSON. We do this with the following
configuration:

<util:map id="jsonNamespaceMap" map-class="java.util.Hashtable">
     <entry key="http://www.myCompany.com/product/service/model/1";
value="m"/>
</util:map>

<jaxrs:server id="jaxrsServer"
     address="${jaxrsServerEndpointUri}"
     staticSubresourceResolution="true">

     <jaxrs:serviceBeans>
         <bean
class="com.company.productname.servicename.services.jaxrs.XYZResourceImpl"
/>
     </jaxrs:serviceBeans>

     <jaxrs:providers>
         <bean class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
             <property name="namespaceMap" ref="jsonNamespaceMap" />
         </bean>
         <bean class="org.apache.cxf.jaxrs.provider.JAXBElementProvider" />
     </jaxrs:providers>
</jaxrs:server>

You can read more about it here:

Best,

I have a resource class with method defined like this
@Produces({"application/json"})
         public Response getMessage(
                         @PathParam("referenceTypeName") String name,
@QueryParam("")
ReferenceDataRequest query)
{
    return null
}

Then i have applicationcontext.xml for camel as shown below:

- <jaxrs:server id="restService" staticSubresourceResolution="true">
-  <jaxrs:serviceBeans>
       <ref bean="restResource" />
   </jaxrs:serviceBeans>
- <jaxrs:providers>
   <ref bean="cxfJaxrsJsonProvider" />
      </jaxrs:providers>
   </jaxrs:server>

  <bean id="cxfJaxrsJsonProvider"
class="org.apache.cxf.jaxrs.provider.json.JSONProvider" />
  <bean id="restResource" class="com.bms.web.HelloResource" />




- <cxf:rsServer id="HelloRsServer" serviceClass="com.bms.web.HelloResource"
loggingFeatureEnabled="true">

   </cxf:rsServer>


- <camelContext xmlns="http://camel.apache.org/schema/spring";>

-
- <route id="restToSoap" streamCache="true">

   <from uri="cxfrs://bean://HelloRsServer?bindingStyle=SimpleConsumer" />
   <log message="**************** Got ${headers}" />
   <log message="**************** Got Body 111 : ${body}" />
   <to uri="bean:reqProcessor" />
   <log message="**************** Got Headers 222 : ${headers}" />
   <log message="**************** Got Body 333 : ${body}" />
   <to uri="cxf:bean:target_hello" />
   <log message="**************** Got Body 444 : ${body}" />
   <to uri="bean:restRespProcessor" />
   <log message="**************** Got Body 555 : ${body}" />

   </route>
   </camelContext>

My Processor is doing
