Java調用WebService方法總結(8)--soap.jar調用WebService

Apache的soap.jar是一種歷史好久遠的WebService技術，大概是2001年左右的技術，所需soap.jar能夠在http://archive.apache.org/dist/ws/soap/version-2.3.1/下載；本文簡單記錄下其調用WebService的方法。文中所使用到的軟件版本：Java 1.8.0_19一、soap 2.3.1。

一、準備

參考Java調用WebService方法總結(1)--準備工做

二、調用

這種方式調用本地服務成功了，但調用在線的服務時返回值老是爲空，參數沒傳過去，估計須要設置參數的命名空間，但又沒找到相關方法。

package com.inspur.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;
