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 xmlns:java=”http://xml.apache.org/axis/wsdd/providers/java”> value=”org.apache.axis.attachments.AttachmentsImpl”/>
type=”java:org.apache.axis.transport.local.LocalResponder”/> type=”java:org.apache.axis.handlers.http.URLMapper”/> type=”java:org.apache.axis.providers.java.RPCProvider”/> type=”java:org.apache.axis.handlers.SimpleAuthenticationHandler”/> type=”java:org.apache.axis.providers.java.MsgProvider”/> http://xml.apache.org/axis/wsdd/ value=”com.jagie.j2me.ws.StringProcessor”/>
