为什么我写的servlet的第一页无法选中？
无论怎么换页页码1都无法选中；
主要代码如下
for(int i=1;i<=pageCount;i++){
if(i==pageNow){
pw.print(""+ i + "");
}
else{
pw.print(""+ i + "");
}
}
全部的代码：
package com.ads;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
public class Success extends HttpServlet{
ResultSet rs = null;
PreparedStatement pstmt = null;
Connection conn = null;
public void doGet(HttpServletRequest req,HttpServletResponse res){
try{
String u = req.getParameter("uname");
String p = req.getParameter("pass");
HttpSession hs = req.getSession(true);
String val =(String)hs.getAttribute("pas");
PrintWriter pw = res.getWriter();
if(val==null){
res.sendRedirect("login");
}
int pageSize = 3;
int pageNow = 1;
int rowCount = 0;
int pageCount = 0;
String sPageNow = req.getParameter("pageNow");
if(sPageNow!=null){
pageNow = Integer.parseInt(sPageNow);
}
pw.println("<body>");
pw.println("<img src=Images/Penguins.jpg width=200px><br/>");
pw.println("hello,u:"+ u + "p:" + p);
pw.println("<a href=# >return login</a>");
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:orcl","scott","zhushaowei12");
pstmt = conn.prepareStatement("select count(*) from users");
rs = pstmt.executeQuery();
if(rs.next()){
rowCount = rs.getInt(1);
}
if(rowCount%pageSize==0){
pageCount = rowCount/pageSize;
}
else{
pageCount = rowCount/pageSize + 1;
}
pstmt = conn.prepareStatement("select * from (select a1.*,rownum rn from (select * from users) a1 where rownum<=?)where rn>=?");
pstmt.setInt(1,pageSize*pageNow);
pstmt.setInt(2,pageSize*(pageNow-1)+1);
rs = pstmt.executeQuery();
pw.println("<table border=1>");
pw.println("<tr><td>id</td><td>username</td><td>password</td><td>email</td><td>grade</td>");
while(rs.next()){
pw.println("<tr>");
pw.println("<td>"+rs.getInt(1)+"</td>");
pw.println("<td>"+rs.getString(2)+"</td>");
pw.println("<td>"+rs.getString(3)+"</td>");
pw.println("<td>"+rs.getString(4)+"</td>");
pw.println("<td>"+rs.getInt(5)+"</td>");
pw.println("</tr>");
}
pw.println("</table");
for(int i=1;i<=pageCount;i++){
if(i==pageNow){
pw.print("<a href=success?pageNow="+ i +">"+ i + "</a>");
}
else{
pw.print("<a href=success?pageNow="+ i +">"+ i + "</a>");
}
}
pw.println("</body>");
}
catch(Exception e){
e.printStackTrace();
}
}
public void doPost(HttpServletRequest req,HttpServletResponse res){
this.doGet(req,res);
}
}
