不知道你什么错，检查rectangle.jsp第三行！是你JSP页面的错误。
----------------解决方案--------------------------------------------------------
jsp页面哪里的问题？请具体点

没家双引号吧，加上试试！
----------------解决方案--------------------------------------------------------
/rectangle.jsp(3,35) quote symbol expected 缺少引号的意思
<jsp:useBean id="rectangle" class=bean.Rectangle scope="page"/> ，class="....."你没加引号
