咱们看看,怎么解决这个问题:

检查一下,发现:

E:\apache-tomcat-6.0.10\webapps\hello\WEB-INF\web.xml

里面:

  <servlet-mapping>

    <servlet-name>HelloServlet</servlet-name>

    <url-pattern>hello.do</url-pattern>

  </servlet-mapping>

</web-app>

这里的配置:

  <servlet-mapping>

    <servlet-name>HelloServlet</servlet-name>

    //1.注意应该把hello.do改成/hello.do

    <url-pattern>/hello.do</url-pattern>

  </servlet-mapping>

</web-app>

这样就可以了.
