第一个程序90.jsp 如下：
<html>
<body>
<center>
<table border=3>
<tr>
<td>use javaBean in jsp</td></tr></table>
</center>
<p>
<jsp: useBean id="pr" class="xiang.numbered"/>
<jsp: setProperty name="pr" property="numd"/>
<jsp: setProperty name="pr" property="nump"/>
some<jsp:getProperty name="pr" property="numd"/>
digitprimes:<jsp:getProperty name="pr" property="numl"/>
</body>
</html>
第二个程序！如下：
package xiang;
import java.lang.Math;
public class numbered
{
private int nump=3;
private int numd=4;
private String numl="";
public numbered()
{
cout();
}
public static void main(String[] args)
{
}
public void cout()
{
int i=nump-1;
int j=0;
boolean is=true;
while(numd>0 && j<numd)
{
i++;
int m=(int) java.lang.Math.sqrt(i);
for(int k=2;k<m;k++)
{
if(i% k==0)
{
is=false;
break;
}
}
if(is)
{
j++;
Integer t=new Integer(i);
numl=numl+t.toString()+"";
}
else
{
is=true;
}
}
}
public int getnumd()
{
return(numd);
}
public String getnuml()
{
return numl;
}
public void setnumd(int message)
{
this.numd=message;
}
public void setnump(int message)
{
this.nump=message;
}

}
可是我在 我怎么也不对！都4个小时了，都是如下错误！

谢谢你，楼上！这个Bean 的装载，<jsp: useBean id="pr" class="xiang.numbered"/>
这中装载方法不对吗？xiang 是一个包，numbered 是numbered.class 文件，我总是搞不懂，为什么有这句话，就有错误！
