    汗....在某次eclipse崩溃后,就打不开了.......汗......
      

  3.   

    我运行了一下你的JSP源码，没有问题。
    那就可能是你WEB容器有点问题，可能缺少某个JAR包或者原有的被破坏了

    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
        pageEncoding="ISO-8859-1"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

    </html>
    这个以前能运行的........这个页面貌似也不会出问题吧........瀑布汗...........我怀疑是某次eclipse崩溃后的后遗症.................tomcat我也重装了.............只能再试试重装JDK了..................

    汗....JDK也重装了.........问题依旧.............
      

  7.   

    Found the problem/solution. The error occurs because Tomcat uses java 
    5.0 while the servlet has been compiled with java 1.4. Compiling the 
    servlet with 5.0 resulted in a much nicer log看看这个链接
