利用J2SE的ksoap2標準，做一個android連接webservice。
因爲soap封裝的關係，android application在接收到數據後不能夠正確的按照J2SE的標準來獲取。
在運用之前，我們先要引導兩個jar進入工程的buildpath
commons-httpclient.jar
ksoap2-android-assembly-2.4-jar-with-dependencies.jar
這兩個jar包都可以在網上查到下載，引導完後再做一項準備工作。
webservice接口：http://192.168.0.2:8080/axis2/services/Manager?wsdl
在android當中，不能寫localhost，必須寫清楚PC機當前的網絡IP
在文件：AndroidManifest.xml放入：
<uses-permission android:name="android.permission.INTERNET"/>
