[翻译]CXF用户指南：一个简单的JAX-WS服务
原文地址：http://cxf.apache.org/docs/a-simple-jax-ws-service.html

这个例子将通过编写JAX-WS来引导你开发第一个服务

    设置构建编写服务发布服务访问服务
同样在CXF发布包中的也可以找到hello_world_code_first示例，注意：这个示例只有在CXF 2.0.1+的版本中！

设置构建

如果你使用Maven来构建你的工程，查看这个页面
否则，打开你最喜爱的IDE，然后创建一个新的工程，我们首先要做的是将CXF依赖的包添加到工程里，你可以在CXF的发布包的ib目录下找到这些依赖包（提示：如果发布包的版本改变，这些jar包上的版本数字可能有所不同）
在实现类上的@WebService注解使CXF知道使用那个接口来创建WSDL，我们示例中是HelloWorld接口

发布服务
return "out message";
}

}


启动服务报错，楼主有碰到过吗？

从报错的信息看出是HelloWorldImpl没有正确加载，你是采用Web工程来编写，所给信息不是很全，我也不能断定是什么问题，示例中是Java工程，通过http://svn.apache.org/repos/asf/cxf/trunk/distribution/src/main/release/samples/java_first_jaxws/src/demo/hw/server/Server.java中Server类的调用Jetty来发布的服务，我试过没有什么问题。return "out message";
}

}

我是通过weblogic10进行发布的，同样的工程在tomcat下发布没有问题，在weblogic下发布需要进行什么特殊的配置吗？     [java] at com.sun.xml.internal.ws.transport.http.server.HttpEndpoint.publish(HttpEndpoint.java:269)

有木有这个class，你看了吗    15 楼    zhengshuo    2011-04-19              当然没有这个class啊，SayHi 是helloworld中的一个方法而已
    16 楼    dandan_5956    2011-04-19              你把你代码的关键部分贴出来看看    17 楼    zhengshuo    2011-04-19              代码跟lz的是一样的，最后找到原因是因为我的jdk版本低了，升级到1.6 u4以上就ok了！
