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,
Fmachado
