jsp中如何调用web service （vb.net写的，目前在asp中调用没有问题！）

[qianguob]

下面是我调用的代码：各位看看有什么问题！

<%@ page language="java"%>
<%@ page import="java.net.*"%>
<%@ page import="java.util.*"%>
<%@ page import="java.io.*"%>
<%@ page import="java.rmi.*"%>
<%@ page import="javax.xml.namespace.QName" %>
<%@ page import="org.apache.axis.client.Service" %>
<%@ page import="org.apache.axis.client.Call" %>
<%@ page import="javax.xml.rpc.ParameterMode" %>
<%
String location="http://localhost/goodsservice.asmx?wsdl";
URL url = new URL(location);
Call call = new Call(url);
call.setUseSOAPAction(true);
call.setTargetEndpointAddress(new java.net.URL(location));
//call.setSOAPActionURI("http://localhost/goodsservice.asmx");
call.setOperationName(new QName("http://localhost/goodsservice/","TestAccount"));
call.addParameter("SiteID",org.apache.axis.Constants.XSD_STRING,ParameterMode.IN);
call.addParameter("password",org.apache.axis.Constants.XSD_STRING,ParameterMode.IN);
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
String number = (String)call.invoke(new Object[] {"123", "123"});
System.out.println(number);
%>

执行以后老是提示：（我用的是tomcat4.1）
type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

org.apache.jasper.JasperException: System.Web.Services.Protocols.SoapException: 服务器未能识别 HTTP 标头 SOAPAction 的值：。

可惜还是不明白：
call.setOperationName(new QName("http://www.my.com/SU","IntAdd"));
这里的地址是 什么？


String endpoint="http://localhost/goodsservice.asmx?wsdl";
Service service = new Service();
Call call = (Call)service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endpoint));
call.setOperationName(new QName("http://localhost/goodsservice.asmx?wsdl","TestAccount"));

call.addParameter("SiteID",org.apache.axis.Constants.XSD_STRING,ParameterMode.IN);
call.addParameter("password",org.apache.axis.Constants.XSD_STRING,ParameterMode.IN);
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
call.setUseSOAPAction(true);
String number = (String)call.invoke(new Object[] {"123", "123"});
System.out.println(number);

这是我写的， CMIC(大象) 帮忙看看 有什么问题？
能给正确的例子，谢谢，急用啊。
