java includes and vars

head.jsp
index.jsp
foot.jsp

is there any way to pull variables i declared in head.jsp into index.jsp?

i noticed that i had to re-declare all my imports in index.jsp, even though i included head.jsp in index.jsp.

php makes it like one big long page.

<%@ include file="<whatever>" %>

yes, i do that.
but lets look at this

thispage.jsp

Code:

String pagetTitle = "This Page";
<%@ include file="head.jsp" %>
now the rest of the page

head.jsp

Code:

<html>
<title><%=pageTitle%></title>
<body>

u see what i mean? i want my vars declared before head.jsp to be recognized in head.jsp... or vars i declare in head.jsp to be recognized in thispage.jsp below where i included the head.

is it possible?

Ah, I see. Files are processed inside-out. Here's how I handle headers:

Code:

    <jsp:include page="/template/title.jsp">
      <jsp:param name="page_name" value="Administration" />
    </jsp:include>

hmm .. i haven't seen it done like that.

so what does that part of /template/title.jsp look like?

It's just a value passed to /template/title.jsp, you can grab it with a request.getParameter("page_name").
