org.apache.jasper.JasperException: Unable to compile class for JSP:

tomcat页面引入自定义类
我自己写了个类：
public class Test
{
public void speak()
{
System.out.println("hello world");
}
}
编译成CLASS后放在ROOT\WEB-INF\classes文件夹下， 然后在页面中引用：
<%@ page import = "Test"%>
我在页面中只写了上面一行， 没有其他的。
但是老不成功， 请高手们帮下我， 我搞了一天了， 没搞定， 谢谢//
