1, http://localhost:8080/MyWebApp/HelloWorld.jsp
3, http://localhost:8080/MyWebApp/AccessCounts.jsp 最佳实践 ： 尽量不要在Servlet中，设计成员变量
4, http://localhost:8080/MyWebApp/BGColor.jsp?bgColor=red 知识点4 ： request.getParameter("bgColor");
String bgColor = request.getParameter("bgColor");
boolean hasExplicitColor;
if (bgColor != null) {
hasExplicitColor = true;
} else {
hasExplicitColor = false;
bgColor = "WHITE";
}
%>
<BODY BGCOLOR="<%= bgColor %>">
5, <% %> 之中的，运行在服务器端，其他html语句运行在客户端 知识点5 ： 注释语句
6, http://localhost:8080/MyWebApp/TestDirective.jsp 知识点6 ： 编译指令
<%@page import="java.util.*" session="false"%>
<%@page contentType="text/html;charset=gb2312"%>
<%= new Date() %>
<%
out.println("ÄãºÃ!");
%>
Jsp 编译指令
(Directive-page)
7, http://localhost:8080/MyWebApp/TestErr.jsp 知识点7 ： 错误转到
<%@page errorPage="ErrPage.jsp"%>
<%
String s="123Plus";
int i=Integer.parseInt(s);
out.println("s=" + s + " i=" + i);
%>
http://localhost:8080/MyWebApp/ErrPage.jsp
<%-- ********* ErrPage.jsp ********** --%>
<%@ page contentType="text/html;charset=gb2312" %>
<%@ page isErrorPage="true" %>
<HTML>
<BODY TEXT="red">
ŽíÎóÐÅÏ¢£º<%= exception.getMessage() %>
</BODY>
</HTML>
8, http://localhost:8080/MyWebApp/TestBar.jsp 知识点8 ： 静态包含
<%@page contentType="text/html;charset=gb2312"%>
<HTML> <!-- *************** TestBar.jsp ***************** -->
<HEAD>
<TITLE>TestBar.jsp</TITLE>
</HEAD>
<BODY>
<TABLE WIDTH="100%">

9, http://localhost:8080/MyWebApp/include/include.jsp 知识点9 : 动态包含 （不常用）
http://localhost:8080/MyWebApp/include/date.jsp
10, http://localhost:8080/MyWebApp/forward/test.jsp 知识点10 : 转向
http://localhost:8080/MyWebApp/forward/forward.jsp
http://localhost:8080/MyWebApp/forward/forward1.jsp
