[jboss-user] [JBossWS] - receiving a AxisFault in the client

[flaviafm]

Hi all,

I'm starting study Web services and I'm trying to use a client to test the web service that I just create and I'm receiving the follow error em I execute the client program. I'm using Eclipse 3.2 and Jboss4.0.1ps1

The client source is :

  | package com.myapp;
  | 
  | import javax.xml.namespace.QName;
  | import javax.xml.rpc.Call;
  | import javax.xml.rpc.Service;
  | import javax.xml.rpc.ServiceFactory;
  | import javax.xml.rpc.ParameterMode;
  | 
  | 
  | public class DIIClient {
  |    	
  |    	// modified from sun j2ee jaxrpc example
  | 	
  | 	private static String endpoint = "http://localhost:8080/simple-ws4ee/ws4ee/services/HelloWorld";
  |    	private static String qnameService = "HelloWorldService";
  |     private static String qnamePort = "HelloWorld";
  | 
  |     private static String ENCODING_STYLE_PROPERTY ="javax.xml.rpc.encodingstyle.namespace.uri"; 
  |     private static String NS_XSD = "http://www.w3.org/2001/XMLSchema";
  |     private static String URI_ENCODING = "http://schemas.xmlsoap.org/soap/encoding/";
  |     
  | 
  |     public static void main(String[] args) {
  | 
  |         System.out.println("Endpoint address = " + endpoint);
  | 
  |         try {
  |             ServiceFactory factory = ServiceFactory.newInstance();
  |             Service service = factory.createService(new QName(qnameService));
  |     
  |             QName port = new QName(qnamePort);
  |     
  |             Call call = service.createCall(port);
  |             call.setTargetEndpointAddress(endpoint);
  |     
  |             call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean(true));
  |             call.setProperty(Call.SOAPACTION_URI_PROPERTY, "");
  |             call.setProperty(ENCODING_STYLE_PROPERTY, URI_ENCODING);
  |             QName QNAME_TYPE_STRING = new QName(NS_XSD, "string");
  |             call.setReturnType(QNAME_TYPE_STRING);
  | 
  | 
  |             call.setOperationName(new QName(endpoint, "getHelloWorld"));
  |             call.addParameter("String_1", QNAME_TYPE_STRING, ParameterMode.IN);
  |             String[] params = { "jboss!" };
  | 
  |             String result = (String)call.invoke(params);
  |             System.out.println(result);
  | 
  |         } catch (Exception ex) {
  |             ex.printStackTrace();
  |         }
  |     }
  | }
  | 

The error is:

When I test my web service with Eclipse Web services Explorer I receive the right response. What is wrong with my client?

thanks,
