标签： java tomcat servlets eclipse-kepler

我正在使用apache-tomcat-7.0.55和java 1.7.0_67从Dynamic Web Project eclipe kepler SR2运行servlet文件 运行XmlServlet.java时在eclipse中的服务器控制台中收到以下错误。我在PC和项目中使用相同版本的Java运行时。

此外，我没有采用相同的方式。

[控制台出错，浏览器中有404]

答案 0 :(得分：0)

您只需进行一次修改

<servlet-mapping>
    <servlet-name>XmlServlet</servlet-name>
    <url-pattern>/XmlServlet</url-pattern>
  </servlet-mapping>

在url-pattern中的Xml Servlet之前添加一个反斜杠并检查。
