JSP语法
我已经会java了，但我还不会jsp呢，就是不知道怎么样写jsp文件呀。请高手指点一下。
[解决办法]
网上的例子 很多的 找个例子自己敲一下就ok了
[解决办法]
所谓的JSP也就是把HTML，JS，JAVA等套在他的格式里，你可以先把JSP的页面指令啥的看看，然后找点例子做做，有JAVA基础，上手JSP还是比较容易的
[解决办法]
页头
<%@ page language= "java " contentType= "text/html; charset=gb2312 " %>
引用错误页
<%@page errorPage = "/common/error.jsp " %>
使用javabean
<jsp:useBean id= "Pool " scope= "page " class= "test.Hello "/>
导入
<%@page import= "java.sql.* "%>
<%!-声明成员变量-%>
如： <%!String a,b,c%>
<%存放Java代码%>
如： <%
a= "aa "
if( "aa ".equals(a)){
out.println( "ok ");
//注释
}
%>

找个例子，配个服务，一试便知！

有一本书 < <Servlet与jsp核心编程> > 第二版 美国Marty hall Larry Brown著 赵学良翻译
里面充分讲解了什么是Servlet 以及Servlet与JSP的关系,写的非常不错 建议看一看
