给你发个我的分页
<%
int PageSize; //一页显示的记录数
int RowCount; //记录总数
int PageCount; //总页数
int intPage; //待显示页码
String strPage;
int i;
PageSize =3; //设置一页显示的记录数
strPage = request.getParameter("page"); //取得待显示页码
if(strPage==null){//表明在QueryString中没有page这一个参数，此时显示第一页数据
intPage = 1;
}else{//将字符串转换成整型
intPage = Integer.parseInt(strPage);
}
if(intPage<1) {
intPage = 1;
}
rs.last();//光标在最后一行
RowCount = rs.getRow();//获得当前行号
PageCount = (RowCount+PageSize-1) / PageSize; //记算总页数
if(intPage>PageCount){
intPage = PageCount; //调整待显示的页码
}else if(PageCount>0){
rs.absolute((intPage-1) * PageSize + 1); //将记录指针定位到待显示页的第一条记录上
i = 0; //显示数据

while(i<PageSize && !rs.isAfterLast()){


%>
第<%=intPage%>页 共<%=PageCount%>页
<%if(intPage<PageCount){%>
<a href="teacher.jsp?page=<%=intPage+1%>">下一页</a>
<%}%>
<%if(intPage>1){%>
<a href="teacher.jsp?page=<%=intPage-1%>">上一页</a>
<%}%>

希望你需要分页的内容不多,楼上的做法否则会死人的....
mysql有专门的分页语句 limit
其他数据库都有相关的分页语句,但是偶是不知道了.如果用hibernate就可以屏蔽掉这些差别.


恩,好久不来了,一来就灌水,见谅
