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/serviceTest
			String 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 block
			e.printStackTrace();
		} catch (RemoteException e) {
			// TODO Auto-generated catch block
			e.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。
