java中调用.net webservice出现(400)Bad Request错误
代码如下：

Java code

package com.how.client;

import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;

import org.apache.axis.Constants;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class ClientTest {

    public static void main(String[] args) {
        
        String url="http://119.97.200.187/WebServiceJyzx.asmx?wsdl";  
        String namespace = "http://tempuri.org/";  
        String methodName = "Getbdxx";  
        String soapActionURI = "http://tempuri.org/Getbdxx";  
        Service service = new Service();  
        try{
        Call call = (Call) service.createCall();  
        call.setTargetEndpointAddress(new java.net.URL(url));  
        call.setUseSOAPAction(true);  
        call.setSOAPActionURI(soapActionURI);  
        call.setOperationName(new QName(namespace, methodName));  
        call.addParameter(new QName(namespace,"42010520091124008"),Constants.XSD_STRING,ParameterMode.IN);
        call.setReturnType(Constants.XSD_STRING);  
        String ret = (String) call.invoke(new Object[]{"222"});  
        System.out.println("返回结果---> " + ret);
        }catch(Exception e){
            e.printStackTrace();
        }    
    }

}

出现下面的错误：

------解决方案--------------------
楼主，建议你先试用myeclipse自带的webservice客户端工具，看看是不是这个服务本身存在问题。排除这个问题后，再继续和楼主讨论。
