Re: REST service : No message body writer has been found

[Bertrand TROLARD]

Hi,

For the problem with the runtime, Eclipse was configured to use JVM 1.6 
by default, it's Ok now with JVM 1.8.

The same function on the web-service but the return valeu is a String 
instead of an int and it works.
    @POST
    @Path("/state0/")
    public *String *getStateBatchResultREST(@QueryParam("uid") String 
szIDDataSource);
>>> OK

    @POST
    @Path("/state1/")
    public*int* getStateBatchResultREST1(@QueryParam("uid") String 
szIDDataSource);
>>>> KO

I have the same result with CXF 3.2.6

Thanks,

Could you test it with one of the latest releases (CXF 3.2.6 / 3.1.16) in
case it's a bug that has been subsequently fixed?

Hi,

I got a problem with a REST service when I use CXF 3.x, it's working
fine with CXF 2.7.
"No message body writer has been found for class java.lang.Integer"

Response-Code: 500
Content-Type: text/plain
Headers: {Content-Type=[plain/text], Date=[Fri, 14 Sep 2018 13:41:18 GMT]}
Payload: No message body writer has been found for class
java.lang.Integer, ContentType: plain/text


I got this error with this function :
      @POST
      @Path("/state/")
      public int getStateBatchResult(@QueryParam("uid") String id);


I use SPRING to define the service
      <jaxrs:server xmlns:tns="http://www.xxx/AnalyzeRESTService";
id="restServer" address="/asynchrone" serviceName="tns:AnalyzeREST" >
          <jaxrs:serviceBeans>
              <ref bean="serviceImplCXF"/>
          </jaxrs:serviceBeans>
          <jaxrs:features>
              <bean class="org.apache.cxf.feature.LoggingFeature" />
          </jaxrs:features>
          <jaxrs:dataBinding>
              <bean class="org.apache.cxf.jaxb.JAXBDataBinding"/>
          </jaxrs:dataBinding>
      </jaxrs:server>

but we have no problem with this one :
      @POST
      @Path("/result/")
      @Produces({"plain/text"})
      public DataHandler getBatchResultDH(@QueryParam("uid") String id,
              @QueryParam("comp") int typeCompression);


I test it with eclipse, Java 8, CXF 3.1.4 or 3.0.16

Do I miss some dependencies or something else ?

Thanks,
Bertrand
