你写的代码虽然简单，可是我不会java,还是不会用，我急需实现这个功能，请求你的帮助，我该怎么做？我把的写的代码的前一部分摘出来命名为：pageControl.java 并运行。
public class pageControl
{
    public int curpage ; 
    public int maxpage ; 
    public int maxrowcount ; 
    public int rowsperpage ; 
    
    
    /*public int getRowsperpage()
    {
        return this.rowsperpage;
    }
    public void setRowsperpage(int rowsperpage)
    {
        this.rowsperpage = rowsperpage;
    }
    public int getCurpage()
    {
        return this.curpage;
    }
    public void setCurpage(int curpage)
    {
        this.curpage = curpage;
    }
*/
//  public yourDataType yourdata ;
    public void calMaxPage() 
    {   //Calculate total page number
        if (this.maxrowcount % this.rowsperpage==0)
        {
        this.maxpage = this.maxrowcount/this.rowsperpage;
        }
        else
        {
    this.maxpage = this.maxrowcount/this.rowsperpage + 1;        
        }
    }
    }剩余代码写入jsp打开jsp时，出错：

找不到你写的那个类，看看你写的类是不是放对地方了，你用的是什么服务器，tomcat？weblogic？tomcat,weblogic都有自己的类路径，跟java编译的类路径是不同的，不过可以自己设置类路径,还有就是你写的代码太狗屁了
