它好象说booklist2.jsp的36行出错..
但是36行是 " <% "的代码片段的开头..
这个分页代码是我从网上搜索回来的..
之前booklist2.jsp显示数据是没有问题的..
下面贴出我booklist2.jsp的代码:
<%@ page contentType= "text/html;charset=gb2312 " %>
<%@ include file= "incoming/common.jsp "%>
<html>
<head>
<title> 网络书店 </title>
<%
DBSQLManager dbsm = new DBSQLManager();
String sql= "SELECT * FROM bookinfo order by DATET DESC ";
dbsm.setSqlStr(sql);
dbsm.executeQuery();
ResultSet rs=dbsm.getRs();
int i;
%>
<%
String pg=request.getParameter( "pg ");
if(pg==null)
pg= "1 ";
int tt;//记录总数
rs.last();
//得到纪录条数
tt=rs.getRow();
//指回接过级首位
rs.first();
int pagex;
//这里的 tt%10 为每页显示纪录的条数，可以自己定义
if(tt%10==0)
//这里计算共多少页，有于数，那么页数+1
{pagex=(tt/10);}
else
{pagex=(tt/10)+1;}//计算总页数
int pagey;//从用户那里得到的目标页
pagey=Integer.parseInt(pg);
如果页数小于1，那么把页数设置成1
if(pagey <1)
{
pagey=1;
}
//如果页数大于总页数，那么设置成最大页数
if(pagey> pagex)
{
pagey=pagex;
}
//翻页开始,调整记录指针的位置
int n=(pagey-1)*10+1;
int a;
for(a=0;a <n-1;a++)
{
if(!rs.isLast())
rs.next();
}
//翻页结束
%>

if ((pagey-1)> =1){
%>
<a href= "booklist2.jsp?pg= <%=(pagey-1)%> "> 上一页 </a>
<%}
else{out.print( "上一页 ");}
%>
|
<%
if ((pagey+1) <=pagex){
%>
<a href= "booklist2.jsp?pg= <%=(pagey+1)%> "> 下一页 </a>
<%}
else{out.print( "下一页 ");}
%>
| <a href= "booklist2.jsp?pg= <%=pagex%> "> 尾页 </a>  每页10条 共 <%=pagex%> 页

<select name= "pg " id= "pg ">
<%
int pg1=0;
for(pg1=1;pg1 <=pagex;pg1++){
%>
<option value= " <%=pg1%> " <%
if(pagey==pg1)
{out.print( "selected ");}
%> > <%=pg1%> </option>
<%}%>
</select>


页
<input type= "submit " name= "Submit " value= "go ">
</div>
</form>

<%
rs.close();
%>

<p>   </p>
<%@ include file= "incoming/footer.jsp "%>
</body>
</html>

麻烦大家看看..
谢谢..

[解决办法]
int i;这个是不是应该写在声明里啊？
<%!
int i=0;
%>
[解决办法]
String pg=request.getParameter( "pg ");

改成

String pg = String.valueOf(request.getParameter( "pg "));

如果还报什么错请把错误信息贴出来
[解决办法]
兄弟能问下你的没有异常处理编译不出错吗我在这个问题已经困扰很长时间了
