我一直在关注vogella.com的 Eclipse WTP 的 Servlet 和 JSP 开发。我已经安装了 Tomcat 7,复制粘贴了代码(一个简单的数据访问对象和一个简单的 HpptServlet),然后从 eclipse 启动了服务器。
当我http://localhost:8080/de.vogella.wtp.filecounter/FileCounter
在网络上打开时,预期的结果是:
但我收到了 404 错误:
这个错误日志在控制台中:

相关信息:
- Tomcat 从命令行 (
catalina run
) 运行正常。 - 只有一个 Tomcat 实例同时运行。
- 我无法从 Eclipse 运行任何其他 Tomcat servlet。
知道为什么 tomcat 不运行我的简单 Servlet 吗?
