Java调用WebService方法总结(8)--soap.jar调用WebService

Apache的soap.jar是一种历史很久远的WebService技术，大概是2001年左右的技术，所需soap.jar可以在http://archive.apache.org/dist/ws/soap/version-2.3.1/下载；本文简单记录下其调用WebService的方法。文中所使用到的软件版本：Java 1.8.0_191、soap 2.3.1。

1、准备

参考Java调用WebService方法总结(1)--准备工作

2、调用

这种方式调用本地服务成功了，但调用在线的服务时返回值总是为空，参数没传过去，估计需要设置参数的命名空间，但又没找到相关方法。

package com.abc.ws;

import java.net.URL;
import java.util.Vector;

import org.apache.soap.Constants;
import org.apache.soap.Fault;
import org.apache.soap.encoding.SOAPMappingRegistry;
import org.apache.soap.encoding.soapenc.StringDeserializer;
import org.apache.soap.rpc.Call;
import org.apache.soap.rpc.Parameter;
import org.apache.soap.rpc.Response;
import org.apache.soap.util.xml.QName;
