What I am attempting to is make it so I can call ${....} on it's (or
it's child classes) as a part of a template without having to call
pageContext.setAttribute(....) on it first but still want to allow for
normal old JSP to be processed basically each page would be something
like this (backed out the changeset so typing from memory):
<%@page extends="dashboard.web.pages.BasePage"%>
<%@include file="[location of master template]"%>
As I test I replaced the include hi x is ${x} and got the output above.
Larger picture I am attempting to take the following template skeleton
and make it so there is zero in-line java but still treat it as a
normal old jsp page (no weird forwards from other servlets or
whatever) [btw this code works]:
<!-- Copyright (C) 2023 TLAITC and contributors -->
<%
String url=request.getRequestURI();
int split=url.indexOf("/",1);
if(split<0)
split=url.length();
String relUrl=url.substring(split,url.length());
String pageName="";
if(relUrl.equals("/"))
pageName="index";
else
pageName=relUrl;
pageContext.setAttribute("relUrl","/content/"+pageName+"/main.jsp");
%>
<html>
<head>
<%@include file="/widgets/scripts/scripts.jsp"%>
</head>
<body>
<jsp:include page="${relUrl}"/>
</body>
</html>
