为什么我在ＴＯＭＣＡＴ下正常运行的程序，在ＲＥＳＩＮ下无法正常工作，是ＷＥＢ．ＸＭＬ的问题么？急，在线等！

Question

<servlet>
    <servlet-name>debugjsp</servlet-name>
    <description>Added by JBuilder to compile JSPs with debug info</description>
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
      <param-name>classdebuginfo</param-name>
      <param-value>true</param-value>
    </init-param>
    <load-on-startup>3</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>debugjsp</servlet-name>
    <url-pattern>*.jsp</url-pattern>
  </servlet-mapping>
问题出在这里
org.apache.jasper.servlet.JspServlet
resin里面没有这个类
上面的一段servlet在非调试环境下可以删掉
