关于jsp的一些小问题

我想用javabean实现计数
代码如下：
ComputerCount.java
package tom.jiafei;
import java.io.*;
public class ComputerCount{
  int number=0;
  boolean iscome=false;
  File file=new File("Count.dat");
  private void countpeople(){
   if(!file.exists())
     {
     number++;
     try{
        file.createNewFile();
        FileOutputStream out=new FileOutputStream(file);
        DataOutputStream dataOut=new DataOutputStream(out);
        dataOut.writeInt(number);
        out.close();
        dataOut.close();
        }
     catch(IOException ee){}
     }
     else
     { try{ FileInputStream in=new FileInputStream(file);
            DataInputStream dataIn=new DataInputStream(in);
            number=dataIn.readInt();
            number++;
            in.close();
            dataIn.close();
            FileOutputStream out=new FileOutputStream(file);
            DataOutputStream dataOut=new DataOutputStream(out);
            dataOut.writeInt(number);
            out.close();
            dataOut.close();
          }
       catch(IOException ee){}
     }
     iscome=true;
    }
  public int gerNumber(){
    if(iscome==false)
      countpeople();
      return number;
    }
 }
ComputerCount.jsp
<%@ page contentType="text/html;Charset=gb2312" %>
<%@ page import="tom.jiafei.*" %>

<jsp:useBean id="count" class="tom.jiafei.ComputerCount" scope="seeion" /><p>历史访问人数
   <jsp:getProperty name="count" property="number"/>
   人
</body></html>运行jsp时提示错误
