    webParameter is null

    Florian Bauer Newbie

      The call to the webservice works fine but the parameter are null (or 0 in case of int).

      I use a AJAX- Client and send directly the xml.

      the Bean:

      @WebService(
       endpointInterface="com.dooris.ws.TheServicePortType",
       targetNamespace="http://www.tai.it/TheService",
       serviceName="TheService",
       portName="TheServiceSOAP"
      )
      @Stateless
      public class TheServiceImpl implements TheServiceSessionBean
      {
       public final String getHalloWorld()
       {
       return "Hallo Welt ";
       }
      
       public final String sayHallo(int iNameGot)
       {
       return "Hallo " + iNameGot;
       }
      }
      


      the call (xml):

      <?xml version='1.0' encoding='utf-8'?><soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'><soap:Body><sayHallo xmlns='http://www.tai.it/TheService'><arg0>5567</arg0></sayHallo></soap:Body></soap:Envelope>



      and the response (xml)
      Status:200
      RESULT:<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'><env:Header></env:Header><env:Body><ns2:sayHalloResponse xmlns:ns2="http://www.tai.it/TheService"><return>Hallo 0</return></ns2:sayHalloResponse></env:Body></env:Envelope>


      where is my mistake?

          the generated WSDL:

            I have the same problem in jbosws 1.2 and 2.0

            is there any mistake in my request?

            really no idea?!

              Hi,

              I have exactly the same proble with JBOSS 4.2.0 and 4.2.2.

              @Stateless(name = "Facade")
              @Local(Facade.class)
              @Remote(Facade.class)
              @WebService
              public class FacadeImpl implements Facade {
               @WebMethod
               public List<NiveauService> getLastDataNiveauService(String e1, String e2) throws WebPchException {
               System.out.println(e1);
               System.out.println(e2);
               }
              
              }
              


              When I invoke the Webservice from the generated wsdl by a client written in Java with Axis1 or Axis2 or JAXWS2 the parameters e1 and e2 have the correct values.

              When I invoke the Webservice from SOAP Client (under MACOS X) or by a PHP client, both parameters e1 and e2 are null !

              What could be the solution to this problem ?

              Thanks

                Hi,

                I have found one solution get it working. I have to use the annotation @SOAPBinding(style = SOAPBinding.Style.RPC)

                @Stateless(name = "Facade")
                @Local(Facade.class)
                @Remote(Facade.class)
                @WebService
                @SOAPBinding(style = SOAPBinding.Style.RPC)
                public class FacadeImpl implements Facade {
                 @WebMethod
                 public NiveauService[] getLastDataNiveauService(String e1, String e2) throws WebPchException {
                 System.out.println(e1);
                 System.out.println(e2);
                 }
                
                }
                


                But I read everywhere that RPV is "BAD" and "Document" should be used instead. But when I use Document I have the previous error.
                Can somebody tell me if it is worth to implement a RPC solution, or how can I get it working with "Document" ?

                thanks

                    I think the request message you're sending is not valid if you use the Document / Literal style, while it is good for RPC/Lit. RPC/encoded is definitely bad, rpc/lit can be used instead. Anyway, if you need/want to use doc/lit, I would suggest to copy from a soap request created by another ws stack (jbossws itself, axis or tools like soapui, etc.)

                      Also ensure you're sending SOAPAction HTTP header if applicable.
