应用test.jsp

<%@ page contentType="text/Html;charset=GBK"%>
<jsp:useBean id="we" scope="page" class="com.china3cts.common.ReturnTo" />
<%
　String Msg="自动转向中....";
　String Url="http://www.java3z.com";
　we.setMsg(Msg);
　we.setRurl(Url);
　we.setIsA(true);
　we.go(response);
%>

注释说明:

1:保存文件位置

ReturnTo.class ===>web-inf/classes/examples/

test.jsp 任意位置

2,写这个主要是不想页面上出现太多的javascript代码:) 纯粹无聊.

3,测试在tomcat + jdk1.5 + win2k3 下通过.
