java.sql.SQLException: Operation not allowed after ResultSet closed
意思是说你的结果集关闭之后不允许操作，应该是你的dbXline类里面的代码有问题，页面代码没看除错误。可以的话发你的dbXline类来看看！

最后结果集要关掉！
哦，记得所有建立的stamt、con、rs的地方使用完了都要关闭！
finally{
close();
}
所以你的结果集就在调用这些方法后就关闭了，而你的JSP页面里的rs就关闭了，rs是引用传递的，所以在你的rs.next()之后才应该关闭连接。你删除了close();再在你的JSP页面最后再加上close()就应该可以了。
顺便说一下，你这样写类是不规范的,你里面的属性和他的getter和setter方法用一个类来封装,实现操作方法用另一个类d~~~~
