    Problem with typeMapping when turning an EJB into a WebServi

            when i use the client class :

            public static void main(String[] args) throws MalformedURLException, ServiceException, RemoteException {
            
            String urlstr="http://localhost:9001/mywebservices/HelloWorldService?wsdl";
            System.out.println("Contacting webservice at " + urlstr);
            URL url = new URL(urlstr);
            QName qname = new QName("urn:HelloWorldService","HelloWorldService");
            
            ServiceFactory factory = ServiceFactory.newInstance();
            Service service = factory.createService(url, qname);
            
            HelloWorld hello = (HelloWorld) service.getPort(HelloWorld.class);
            System.out.println("Service found");
            System.out.println("hello.getHello(truc)");
            System.out.println(hello.getHello("truc")); <=== return an error

              perhaps it s depend of the SOAP version because i read somewhere that Soap 1.1 can only process atomic variable like char and not string.
              May I perhaps make a new type string (an array of char) ?
              or specify that i want using SOAP 1.2 but i don't know how.

                  An NPE is not acceptable. I assigned this JIRA issue
                  http://jira.jboss.com/jira/browse/JBWS-203

                  Your WS uses rpc/encoded which is not allowed by the BasicProfile-1.0. Try using rpc/literal.

                  Have you seen the StepByStep tutorials in the wiki?

                    i ve read the wiki another time and i've generated rpc/literal files with wscompile but the customer class still send back me a NPE on Call.GetTypeMapping.

                      I hope that one day JBoss will be able to compete with Dotnet about webservices.

                        Well this issue is a absolute SHOW STOPPER.

                        I need to run webservices on my JBoss 4.0.1sp1 installation. I am using wscompile from sun jwsdp-1.5. I am trying to run a simple web service (no EJB). Everything is deployed fine - but the client throws this error always and thus I am stuck. NPE with getTypeMapping. The module is axis-ws4ee.


                        Can anyone tell me is there is a way around to make my services run?. Or when this issue will be resolved ? Can I replace the axis-ws4ee file with a version which doesnot have this problem - even back versions ? If so - where to get the file..

                        Thanks in advance

                          Incidently I tried with both String and int. Same problem - so looks like, it is not an issue with the "String" data type.

                            I currently see this error when I run Java 1.5, but not Java 1.4. So if you're runing 1.5, try 1.4.

                            I had problems in another project with 1.4->1.5 and axis.jar. I solved it by getting a 1.5 axis.jar.

                            But now I'm looking for a 1.5 version of this JBoss fork(?) of axis.jar (axis-ws4ee.jar) and haven't had any luck.

                              The issue target release tells you the expected fix date. You can also become a jboss customer if you business is such that you cannot rely on free support (i.e. you need a patch in a timely manner)

                                I've run into this problem myself and traced it the absence of a client-config.wsdd file on the classpath of the invoking client code (running from an EAR deployed under JBoss) - the Axis engine was picking up the default client-config.wsdd supplied by JBoss which contained references to classes which were not available to my client code. The net result was that the ClassNotFoundException thrown during initialization resulted in a TypeMappingRegistry in the main engine configuration. Or something like that.

                                The moral is: make sure you have a usable client-config.wsdd on your client's classpath.

                                  If you followed

                                  http://wiki.jboss.org/wiki/Wiki.jsp?page=WSRPCServiceStepByStep

                                  Can you post your wsdl, jaxrpc-mapping, SEI. We can look into this further then.
