我正在关注http://www.mkyong.com/webservices/jax-ws/deploy-jax-ws-web-services-on-tomcat/comment-page-1/#comment上的简单示例 Web 服务的教程-130057 - 他仔细列出了所需的库，它们位于 tomcat lib 文件夹和 Web 服务本身的“用户库”部分中。（把那些放在那里让我摆脱了试图完成这件事的最后一条致命错误消息。）我已经看到一篇关于这个错误的帖子，表明“旧的 servlet.jar 可能位于某个地方。”；我在 eclipse 或 tomcat 库目录中都找不到。在tomcat lib目录下有一个servlet-api.jar，里面其实有ServletContainerInitializer。
这是 Tomcat 7，eclipse Juno，不，我不想先停下来学习 Maven。我看到另一篇帖子说，在海报清理并重新安装 JRE/JDK、Tomcat 和 eclipse 后，问题就消失了。我想如果我买了一台新机器，它也会消失，但我希望有一些不那么激烈的东西。
我不希望任何人知道问题是什么——有人可以告诉我如何解决它吗？我正在发布控制台日志的第一部分，以防万一……
