Axis远程调用WebService接口

前提：需要调用webservice接口时，获取到wsdl地址，并清楚里面的相关内容。

1 引入相关jar包：axis相关jar包下载

2 java相关代码，和网上提供的大致相同：

package com.demo.service;import java.rmi.RemoteException;import javax.xml.rpc.ServiceException;import org.apache.axis.client.Call;import org.apache.axis.client.Service;public class MyClient {public static void main(String[] args) {try {// 直接引用远程的wsdl文件地址，如http://www.baidu.com/myService/serviceTestString endpoint = "";Service service = new Service();Call call = (Call) service.createCall();call.setTargetEndpointAddress(endpoint);call.setOperationName("sendInfo");// WSDL里面描述的接口名称call.addParameter("in0",org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);// 接口的参数call.addParameter("in1",org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);// 接口的参数call.addParameter("in2",org.apache.axis.encoding.XMLType.XSD_STRING,javax.xml.rpc.ParameterMode.IN);// 接口的参数call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);// 设置返回类型String result = (String) call.invoke(new Object[] { "", "", "" });// 必须和addParameter方法中设置的参数类型一致// 给方法传递参数，并且调用方法System.out.println("result is " + result);} catch (ServiceException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (RemoteException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

问题1：实际在部署开发的过程中，endpoint一开始填写的是wsdl地址，也就是类似于http://www.baidu.com/myService/serviceTest?wsdl这样的地址。而运行时会报如下错误：

而将http://www.baidu.com/myService/serviceTest?wsdl修改成http://www.baidu.com/myService/serviceTest后，也就是去除"?wsdl"则可正常访问。
