摘要
本文用一个简明的例子，阐述了如何在手机上用KSOAP API来访问本地服务器上的Web Service。并且给出了详细的操作步骤和全部的Server，Client源代码。
1. 服务端
这次要发布的web service非常简单。它的功能是把从客户端传入的字符串中的小写字母转变成大写字母，再返回给客户端。Soap 服务器采用apache的AXIS（可以从http://ws.apache.org/axis/下载），应用服务器可以选用各种servlet 容器，我这里采用的是weblogic。
1.1 实现类的源代码
// StringProcessor.java
package com.jagie.j2me.ws;
public class StringProcessor {
public StringProcessor() {
}
public String process(String name){
return name.toUpperCase();
}
}
1.2 发布步骤
1．准备一个目录作为web application的发布目录,我这里的这个目录叫jagiews,这个目录的全路径中最好不要有空格和中文。我的发布目录结构如下：
2．编译StringProcessor.java,把生成的StringProcessor.class置于: \jagiews\WEB-INF\classes\com\jagie\j2me\ws目录下。
3.在jagiews\WEB-INF\lib 文件夹中置入以下axis服务器需要的jar文件
axis.jar，axis-ant.jar，commons-discovery.jar，commons-logging.jar，jaxrpc.jar，log4j-1.2.8.jar，saaj.jar ，wsdl4j.jar。这些文件可以在http://ws.apache.org/axis/下载，如图所示：
4.在jagiews\WEB-INF目录下增加2个发布描述文件：server-config.wsdd，web.xml。
#server-config.wsdd

5.开启你的application server，把目录jagiews发布为一个名叫jagiews的web application。
6.测试:打开浏览器，输入网址（这里使用的是weblogic,其他的服务器请酌情修改）:
http://localhost:7001/jagiews/services/StringProcess?method=process&name=qqqq，
如果浏览器能在返回的xml文档中显示字符串"QQQQ"，恭喜你，你的web service发布成功了。如果发布不成功，请按以上发布步骤检查一下。
2. 客户端
客户端自然是用MIDlet了，不过用什么方式来访问web service呢？其实有3种访问方
