初学者问题，各位大虾指点！！！（在线等待）

我是在学j2ee编程指南上面的例子。

// FreakServlet.java// Import servlet packages

      log("Flushing state history of LifeCycleTest servlet.");
      for(int i = 0; i < states.size(); i++) {
         log(states.elementAt(i).toString());
      }
   }   private String createState(String message)
   {
      return "[" + (new java.util.Date()).toString() + "] " + message;
   }
}

将doGet改成doPost看看可不可以吧===================================

url是：http://localhost:8000/lifeCycle/servlet/freak---------------------依你提供的程序，URL似乎应该是：http://localhost:8000/lifeCycle/servlet/FreakServlet

web.xml是自动生成的。<?xml version="1.0" encoding="ISO-8859-1"?><!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd"><web-app>
  <servlet>
    <servlet-name>freak</servlet-name>
    <servlet-class>FreakServlet</servlet-class>
    <init-param>
      <param-name>waitInterval</param-name>
      <param-value>5</param-value>

  </servlet>  <error-page>
    <exception-type>javax.servlet.UnavailableException</exception-type>
    <location>/unavailable.html</location>
  </error-page>
</web-app>

我试了好多次，有两次成功的调用了这个servlet，但是我在浏览器上用刷新，就报错了，本来出错就应该调用默认的出错页，但是没有指向默认页，提示currently unavailable，之后就不能调用servlet了。好像应该不是路径的问题吧?

调试易
