用java分页,在jsp中显示

帮楼主顶一下，分页大家一般都会有标签（自定义标签），常用的pagetaglib，你可以看看，里面的注释写的也不错，偶就是跟着这个学的
<%@ page contentType="text/html;charset=gb2312" %>
<%@ page language="java" import="java.sql.*" %><script language="javascript">
function newwin(url) {
var newwin=window.open(url,"newwin","toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=600,height=450");
newwin.focus();
return false;
}
</script>
<script LANGUAGE="javascript">
function submit10()
{
self.location.replace("fenye1.jsp")
}
</script>
