请问这是怎么回事？高手推测错误可能的根源！！我的代码都检查一天了！也累了！

这是错误消息，把你对应的JSP编码贴出来，估计是少了个 { 或  }

解决方案 »

  1.   

    是不是把catch 放到try里了？
      

  2.   

    <%@ page contentType="text/html;charset=gb2312"  language="java" import = "java.sql.*"%>

  3.   

    低级错误未免太多了些.才学吧?
    <1>
    Statement stm=con.creatStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,Resultset.CONCUR_READ_ONLY);
    [con.createStatement][ResultSet]
    ~~~~~~~~~~~~~~~~~~~~~~
    <2>
    管理员： <a href="mailto:<%=getString("email")%>"> <%=rs1.getString("admin")%></a>
    [<%=rs1.getString("email")%>"]楼主还是自己慢慢找咯.
      

  4.   

    所有的代码都没有try---catch块，先学一下代码风格。
      

  5.   

    哎  ！！  是啊 才学的  ！ 经大家提醒错误全部查出来了 就是{,  }等  拼写错误！ 我会把编程风格做好啊！多谢大家！不过做后又出了个问题：请看下面 就这个问题了500 Servlet Exception
