receiving a AxisFault in the client
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,
