1、下载jax-ws依赖包
因tomcat没有jax-ws所需的依赖环境,所以第一步先下载Jax-ws RI,即jax-ws reference implemantation, 地址:http://jax-ws.java.net。
2、安装jax-ws RI到tomcat服务器
先下载ant与tomcat,设置环境变量ANT_HOME与CATALINA_HOME,然后在path下引入各自的bin目录打开命令提示符,在jax-ws ri包的目录下运行ant install。
此命令会直接把需要的包导入到${tomcat}\shared\lib目录下,其实也就是把jaxws RI lib下的包复制到了tomcat安装目录下shared\lib里面。
3、设置Eclipse中的tomcat
由于eclipse是自己定义的tomcat配置文件,所以需要加些东西,把shared\lib加入进来,打开ctalina.properties文件。

- package.access=sun.,org.apache.catalina.,org.apache.coyote.,org.apache.tomcat.,org.apache.jasper.

- # by default, no packages are restricted for definition, and none of
- # the class loaders supplied with the JDK call checkPackageDefinition.
- #
- package.definition=sun.,java.,org.apache.catalina.,org.apache.coyote.,org.apache.tomcat.,org.apache.jasper.

- # classloader. Prefixes should be used to define what is the repository type.
- # Path may be relative to the CATALINA_HOME or CATALINA_BASE path or absolute.
- # If left as blank,the JVM system loader will be used as Catalina‘s "common"
- # loader.
- # Examples:
- # "foo": Add this folder as a class repository
- # "foo/*.jar": Add all the JARs of the specified folder as class
- # repositories
- # "foo/bar.jar": Add bar.jar as a class repository
- common.loader=${catalina.home}/shared/lib/*.jar,${catalina.home}/shared/lib,${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar
找到common.loader配置项增加${catalina.home}/shared/lib/*.jar,${catalina.home}/shared/lib 这两个路径即可
4、建立项目
新建一个web项目,webservice_web,目录结构如下
HelloService.java是提供web service的一个接口,代码如下:
- package com.zxuqian.webservice;
- import javax.jws.WebMethod;
- import javax.jws.WebService;
- @WebService
- public interface HelloService {
- @WebMethod
- String greetings (String name);
- }
HelloServiceImpl.java是实现类,代码如下:
- package com.zxuqian.webservice.impl;
- import javax.jws.WebService;
- import com.zxuqian.webservice.HelloService;
- @WebService (endpointInterface = "com.zxuqian.webservice.HelloService" )
- public class HelloServiceImpl implements HelloService {
- @Override
- public String greetings(String name) {
- return "Hello: " + name;
- }
- }
5、添加sun-jaxws.xml
sun-jaxws.xml是通过web方式发布web service应用的描述文件,内容如下:
- <?xml version="1.0" encoding="UTF-8"?>
- <endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime" version="2.0">
- <endpoint name="HelloWorld" implementation="com.zxuqian.webservice.impl.HelloServiceImpl"
- url-pattern="/hello" />
- </endpoints>
各个节点的具体说明请参考下载的jaxws ri包里面的docs文档,在这里简单说明一下,endpoint需要指定
web service服务的接口和实现类,以及它的url相对路径
6、配置web.xml
内容如下:
- <?xml version="1.0" encoding="UTF-8"?>
- <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
- <display-name>webservice_web</display-name>
- <listener>
- <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
- </listener>
- <servlet>
- <servlet-name>hello</servlet-name>
- <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
- <load-on-startup>1</load-on-startup>
- </servlet>
- <servlet-mapping>
- <servlet-name>hello</servlet-name>
- <url-pattern>/hello</url-pattern>
- </servlet-mapping>
- </web-app>
7、测试
启动tomcat,在浏览器中输入web service地址 http://localhost:8088/webservice_web/hello我的tomcat的端口号是8088,大家根据自己的端口号进行相应的修改。
