Axis开发webservice的简单实例
blog迁移至:http://www.micmiu.com
本文主要记录Axis开发webservice简单实例的详细过程和步骤：
Axis官方网站：http://ws.apache.org/axis/
可以在官网下载最新1.4的包：axis-bin-1_4.zip
将解压后的axis-1_4\webapps\下的axis目录考到%TOMCAT_HOME%/Webapps/目录下
启动tomcat后在浏览器里输入http://localhost:8082/axis会看到下图所示（ps：本人的tomcat端口为8082）
点击上图中的Validataion链接,页面上会提示已经有的包和缺少的包的信息,根据提示将必须的包下载全，将这些类包复制到 %tomcathome%/webapps/axis/WEB-INF/lib/目录下重新启动tomcat,直到Validation页面中看不到有Error与Warning的提示信息。
如果提示缺少xmlsec.jar可以到http://santuario.apache.org/dist/java-library/下载.
Axis支持三种web service的客户端访问方式，分别为：Dynamic Invocation Interface ( DII)Dynamic Proxy方式Stubs方式PS：看到很多资料将上述方式列为Web Servcie的三种“部署和开发方法，个人觉得有些欠妥
下面介绍axis部署和发布web service的方式：
一、JWS
JWS（Java Web Service）是最简单的一种方式。Axis允许把普通Java类的源文件的扩展名改为.jws，然后把它简单的copy到AXIS_HOME下。这样，Axis 会自动编译.jws文件，并把它自动加入到Java Web Servie的服务中。具体过程如下
1.用Eclipse或者文本编辑器编写一个java类SayHello.java(此类不含包名)
public class SayHello{public String sayMsg(String name){return "Hello,"+name;}}
