我把.class文件拷在classes下，目录名newyanhai。这是我的bean码：
package newyanhai;
import java.io.*;
public class MyBean implements Serializable
{
private String name = "hello ,yanhai";
public void setName(String name)
{
this.name = name;
}
public void MyBean()
{
}
public String getName()
{
return name;
}
}这是调用的:
<jsp:useBean id = "yanhais" scope = "session" class ="newyanhai.MyBean"/>
每次运行都有这个问题，已经重起过好几次了：/yanhai/yanhai.jsp(12,0) The value for the useBean class attribute newyanhai.MyBean is invalid.
