多系统（异构系统）进行交互时，一种良好的方式便是调用Web Service，本示例基于Apache组织的CXF，为了方便起见特将服务端和客户端写在同一个工程下，实际项目中是不可能的，但是客户端却依赖于服务 端的Web Service接口，那么可以通过导出jar的方式。
环境：
MyEclipse10
JDK6
Tomcat7
CXF2.5
Spring3
示例项目结构图：
如上图所示，全部依赖的第三方库都在lib中，下面贴出全部代码。
IHelloService.java
package bing.server; import javax.jws.WebService; /** * <p> * WebService接口 * </p> * * @author IceWee * @date 2012-7-6 * @version 1.0 */ @WebService public interface IHelloService { public String sayHello(String username); }
HelloServiceImpl.java
package bing.server; import javax.jws.WebService; /** * <p> * WebService实现类 * </p> * * @author IceWee * @date 2012-7-6 * @version 1.0 */ @WebService(endpointInterface = "bing.server.IHelloService", serviceName = "HelloService") public class HelloServiceImpl implements IHelloService { @Override public String sayHello(String username) { return "hello, " + username; } }
HelloServiceClient.java
package bing.client; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import bing.server.IHelloService; /** * <p> * WebService调用方-客户端 * </p> * * @author IceWee * @date 2012-7-6 * @version 1.0 */ public class HelloServiceClient { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml"); IHelloService helloService = (IHelloService) context.getBean("client"); String response = helloService.sayHello("Peter"); System.out.println(response); } }

所有项目都已配置完成，可以发布到Tomcat了，在浏览器中输入：http://localhost:8080/CXFDemo/ws，返回如图：
从上图中可以看到我们对外发布的WebService接口，点击蓝色超链接，返回如图：
到此，证明我们的Web Service已经发布成功，可以进行调用测试了。运行HelloServiceClient，返回如图：
补充：
1.启动时报错，class not fount
解决：需要加载spring的jar包和cxf的jar包。网上均有资源可以下载引用。
2.测试client端报错
java.lang.LinkageError: 正在从引导类加载器加载 JAXB 2.1 API, 但此 RI (来自jar:file:/D:/Program%20Files/JAVA_JDK_45/lib/endorsed/jaxb-impl- 2.2.6.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) 需要 2.2 API。请使用授权目录机制将 jaxb-api.jar 放在引导类加载器中。(请参阅 http://java.sun.com/j2se/1.6.0/docs/guide/standards/)
解决：需要把jre System Library 放在第一位。
