倒，在webapp目录下建立个项目，具体结构如下

     ----WEB-INF
        ---web.xml
        ---classes
           ---这里就是放javabean的

Circle 是楼主的类名对不对？供 JSP 使用的类，必须放在包中，也就是说要这样定义类：package pkoflz;public class Circle { 
...在 JSP 页面中使用类要有：<%@ page contentType="text/html; charset=gb2312" import="pkoflz.*" %>
如果使用 jsp:useBean，其中的 class 属性要给出完全限定类名，如：<jsp:useBean id="xxx" scope="request" class="pkoflz.Hello" ...
