    Accessing WSDL from an CXF NMR endpoint

      Hi,

       

      I have a CXF web service deployed with an NMR endpoint. I also have a camel route with a jetty endpoint to expose the NMR CXF endpoint. Is there a way to get the WSDL for my service (https://localhost:8084/services/thresholds?wsdl) ? I'm actually getting an exception :

      My camel route :

       

      <camel:route>

                     <camel:from ref="serverURL" />               

                     <camel:choice>

                          <camel:when>

                           <camel:simple>in.header.wsdl</camel:simple>

                           <camel:setHeader headerName="CamelHttpMethod">

                          <camel:constant>GET</camel:constant>

                        </camel:setHeader>

                         

                        <camel:convertBodyTo type="org.apache.camel.converter.jaxp.StringSource" />

                          <!-- <camel:to

                                    uri="nmr:DecisionService" /> -->

                            <camel:to

                                    uri="nmr:wcs1.1" />

                                     

                          </camel:when>

                          <camel:otherwise>

                             <camel:to uri="direct:processRequest"/>

                          </camel:otherwise>

                     </camel:choice>

                </camel:route>

       

       

      Thanks in advance,

          The error message is quite similar as this post.

           

          Try to use StreamSource to convert the body to see if it works for you.

            Thanks Joe for your suggestion but I tried that before but did not work. I believe the problem is that when requesting the WSDL we are doing a GET request with an empty payload so here the exception. But I believe even I get pass this exception the "nmr" processor is not aware  I'm requesting the service WSDL anymore.

             

            Could anybody tell me what is the mechanism that CXF uses to detect the WSDL request and how generates the WSDL on the fly ?

             

            Thanks,
