读取数据库的留言板信息，分页显示出错

这个是我查看留言板的代码<body>
<p align="center">所有访客留言</p> 
<table width="732" height="*" border="1" align="center" cellpadding="1" cellspacing="0" bordercolordark="#ffffff"  bordercolor="#ffffff" bordercolorlight="#0066ff">
  <tr bgcolor="#CCCCFF">
    <td height="22" colspan="5" align="center"><a href="index.jsp?choice=5.jsp">增加留言</a></td>
  </tr>
  <%
Connection con = DriverManager.getConnection("jdbc:odbc:banji");
Statement sql = con.createStatement();
ResultSet rs = sql.executeQuery("select * from message ORDER BY m_date DESC");
String color="";
String strpages=(String)request.getParameter("pages");
int pages=0;
if(strpages==null){
      pages=0;
}else{
              pages=Integer.parseInt(strpages);
}
rs.last();
int sqan=4,i=0,fcount=0;
int count=rs.getRow();
int countpage=count/sqan;

if(count%sqan>0) countpage=countpage+1;

int fpage=(count-fcount)/sqan+1;
out.print(fpage);
rs.absolute(fcount);
rs.previous();

while(rs.next()){
          int id=rs.getInt("id");

</table>
</body>然后运行后报错：org.apache.jasper.JasperException: An exception occurred processing JSP page /view_ly.jsp at line 2724:  }else{
25:               pages=Integer.parseInt(strpages);

27:  rs.last();
28:  int sqan=4,i=0,fcount=0;
29:  int count=rs.getRow();
30:  int countpage=count/sqan;
高手帮我看看，改下代码，谢谢了
