这段JSP如何读？

Question

 <%@ include file="/inc/header.jsp"%>
<%@ page pageEncoding="UTF-8"%>
<%@ page import="com.peuo.wl.util.Constant"%>
<%@ page import="com.peuo.wl.util.SocketService"%>
<%@ page import="cn.myutil.transport.message.Response"%>
<%@ page import="com.opensymphony.xwork.ActionContext" %><p align="left">
<card id="redirect">
  <onevent type="onenterforward">
      <wml:go href="${pageContext.request.contextPath}/newlogin.action"></wml:go>
  </onevent>
</card>
</p>
<%@ include file="/inc/footer.jsp"%>我会JAVA，也写过网络的服务器端程序，但没有接触过JSP。请问这该如何开始？
后面<p></p>好像是自定义标签？如何找呢？
另外 /newlogin.action这个该让哪个java程序段执行？
------
十分谢谢..
没有分了...

Answer 1

/newlogin.action前有个${pageContext.request.contextPath}
它执行的是配置文件中对应名字的java程序

Answer 2

另外：<p>不是自定义标签，具体意思自己去找

Answer 3

楼主的这段代码似乎不全，好像少了一些标签的引入代码。
正常情况下应该是看到自定义标签（比如<card><onevent>...）先找到jsp代码上部的引入部分（比如<%@ taglib uri="/WEB-INF/tld/InputExtends.tld" prefix="ie" %>）其中prefix的值是小名，对应自定义标签的名字，uri则是这个标签的配置文件，找到这个*.tld配置文件后，再根据标签冒号后面的名字找到对应的配置，其中就有处理类，看他源码即可。

Answer 4

LZ你这样问太宽泛了,即便把这两个问题搞懂了,其他的你还是一知半解.还是多了解了解基本东西吧,自定义标签,HTML?

Answer 5

我这个代码全的呢：
具体是： <%@ include file="/inc/header.jsp"%>
<%@ page pageEncoding="UTF-8"%>
<%@ page import="com.peuo.wl.util.Constant"%>
<%@ page import="com.peuo.wl.util.SocketService"%>
<%@ page import="cn.myutil.transport.message.Response"%>
<%@ page import="com.opensymphony.xwork.ActionContext" %>
<% String sid=request.getParameter("sid");
if(sid==null||sid.length()!=4||sid.equals("null")){
sid="0001";
}
request.setAttribute("sid",sid);
Response res=SocketService.getQudInfo(sid);
if(res.getCode()==0){
request.getSession().setAttribute("qudcode",res.getItem("qudcode"));
request.getSession().setAttribute("qudname",res.getItem("qudname"));
request.getSession().setAttribute("qudurl",res.getItem("qudurl"));
if(res.getItem("qudcode").equals("0001")){
request.getSession().removeAttribute("qudcode");
request.getSession().removeAttribute("qudname");
request.getSession().removeAttribute("qudurl");
}
}else{
request.getSession().removeAttribute("qudcode");
request.getSession().removeAttribute("qudname");
request.getSession().removeAttribute("qudurl");
}
%>
<p align="left">
<card id="redirect">
  <onevent type="onenterforward">
      <wml:go href="${pageContext.request.contextPath}/newlogin.action"></wml:go>
  </onevent>
</card>
</p>
<%@ include file="/inc/footer.jsp"%>如果我运行，出来的是一段wap格式的代码。页面显示的是：很抱歉,服务器内部错误。我就像知道这个信息通过哪些JAVA类处理的...

你去看看WML语法吧http://www.hackhome.com/InfoView/Article_171857_2.html

Answer 8

jsp页面好像要完成的功能是：事件触发以实现页面跳转
