    Fail to access the servlet-style web service

    Qingjun Xiao Newbie

      I am using JBoss 4.0.3 SP1.

      According to the instructions from adminguide, I deploy a so-called "JAX-RPC service endpoints (JSEs)". The deployment seems to be successful, if we check it in "http://localhost:8080//ws4ee/services".

      But when i use the following code to access the service, exception is thrown

       String urlstr = "http://localhost:8080/hello-servlet/Hello";
       String argument = "Jack";
      
       System.out.println("Contacting webservice at " + urlstr);
       URL url = new URL(urlstr);
       QName qname = new QName("http://hello.ws.jboss.org/", "HelloService");
       ServiceFactory factory = ServiceFactory.newInstance();
       Service service = factory.createService(url, qname);
       Hello hello = (Hello) service.getPort(Hello.class);
       System.out.println("hello.hello(" + argument + ")");
       System.out.println("output:" + hello.hello(argument));


      Exception in thread "main" javax.xml.rpc.ServiceException: Error processing WSDL document:
      org.xml.sax.SAXException: Fatal Error: URI=http://localhost:8080/hello-servlet/Hello Line=2: Element type "meta" must be followed by either attribute specifications, ">" or "/>".

          all the jar files are copied from jboss client folder including:

          jbossall-client.jar
          axis-ws4ee.jar
          common-discovery.jar
          common-logging.jar
          wsdl4j.jar

          xercesImpl.jar is from the lib\endorsed

          client-config.wsdd is a rename of \server\default\deploy\jboss-ws4ee.sar\META-INF\axis-client-config.xml

            The wsdl file seems to be fine, which is generated by sun's jwsdp 2.0

            <?xml version="1.0" encoding="UTF-8"?>

              Following is the code for accessing the servlet-web service.

              public class WebServiceStandaloneClient {
              
               /**
               * @param args
               */
               public static void main(String[] args) {
              
               try {
               String endPoint = "http://localhost:8080/age/Age?wsdl";
               URL url = new URL(endPoint);
               ServiceFactory sf = ServiceFactory.newInstance();
               QName serviceQname = new QName("http://age.webservices.javasrc.com/","AgeService");
               Service s = sf.createService(url,serviceQname);
               Age age = (Age) s.getPort(Age.class);
               System.out.println("got output " + age.age("name",new Integer(26)));
               } catch (MalformedURLException e) {
               e.printStackTrace();
               } catch (ServiceException e) {
               e.printStackTrace();
               } catch (RemoteException e) {
               e.printStackTrace();
               }
              
               }
              
              }


              You need to create following classes : I generated it using the Eclipse Web Service Client.
              package com.javasrc.webservices.age;
              
              public interface AgeService extends javax.xml.rpc.Service {
               public java.lang.String getAgePortAddress();
              
               public com.javasrc.webservices.age.Age getAgePort() throws javax.xml.rpc.ServiceException;
              
               public com.javasrc.webservices.age.Age getAgePort(java.net.URL portAddress) throws javax.xml.rpc.ServiceException;
              }
              


              There are jaxr,jaxrp,saaj,xml-api.jar, axis.jar, commons-loggin,commons-discovery,log4j and wsdl4j.jar files in the class path of the client.
