我的DW+JaveBean运行不成功？

penging 2006-03-08 10:25:46

我在DW里编了一个简单的页面：
<body>
<jsp:useBean id="coun" scope="session" class="hainan.CountBean"/>
<%coun.setCount(100);%>
你是第
<jsp:getProperty name="coun" property="Count"/>位访问者
</body>

CountBean.java如下:
package hainan;
public class CountBean
{
int count;
public CountBean()
{
count=0;
}
public int getCount()
{
count++;
return count;
}
public void setCount(int num)
{
count=num;
}
}

可是运行时总不成功，我编别的JSP也是一样，请问这是怎么回事呀？

运行后抛出的问题如下：
org.apache.jasper.JasperException: /countbean/counter.jsp(9,0) The value for the useBean class attribute hainan.CountBean is invalid.
