什么是AXIS2就不介紹了，主要介紹的是如何利用AXIS2快速的實現一個Web Service。本文以實例說明了一個Web Service的創建、部署褐調用的過程。
本文使用的AXIS2的版本是1.1.1，Tomcat版本是6.0.10，JDK版本是1.5，操作系統WinXP SP2，IE瀏覽器IE6 SP2。

66?</service>三、文件打包
將類文件和Web服務描述文件打包為aar文件
四、部署
將aar文件復制到<TOMCAT>/webapps/axis2/WEB-INF/services目錄下，并修改文件services.list，將aar文件名復制到該文件并保存。
五、瀏覽器調用
