我已经尝试过http://www.mkyong.com/webservices/jax-ws/jax-ws-hello-world-example-document-style/comment-page-1/#comment-133527上的教程。本教程讲述了如何创建一个 helloworld Web 服务、发布它并通过客户端代码进行尝试。该教程效果很好。我可以使用发布者发布 Web 服务（无需部署???），我可以运行客户端并调用 Web 服务方法并获得答案。
我的 Web 服务代码是另一个 Web 项目的一部分。当我在 tomcat 上部署项目战争文件时，出现错误。当我从项目中删除 Web 服务代码（服务、客户端和发布者）时，我可以部署我的 Web 项目。我检查了 web.xml 文件、sun-jaxws.xml 文件和所有内容一百万次，但我找不到任何东西。请帮忙..
