3 level jsp include

Question

I did a "framework" jsp file, because I have a bunch of pages, that need to look the same, except for the content.
"framework" pseudo code:
DoStuff
*include file X;*
DoSomOtherStuff
*include file Y;*file X depends on the jsp including this framework, example:
myFirstPage.jsp:
X = "myFirstPartX.jsp";
Y= "myNextPartY.jsp";
<%@ include file="framework.jsp" %>Ok, so what type of include can I use in the framework to include X and Y files?
I didn't find any way to create constants in MyFirstPage.jsp that I could use in the include directive so I have to use the jsp:include taglib, where X and Y are variables.
Super, my only problem with the jsp:include is:
- it is more resource consuming isn't it?
- I cannot access variables I declared in myFirstPage.jsp
- a can only pass objects to myFirstPartX.jsp and myNextPartY.jsp via the request.setAttribute
It's seems like a trivial problem, being able to use a different include directive based upon the top level page (macros, constants?), is there no better solution than a jsp:include ?

2. if you need to pass string type information you can use jsp:param
<jsp:include page="x.jsp">
   <jsp:param name="param1" value="value1"/>
   <jsp:param name="param2" value="value2"/>
</jsp:include>
<jsp:include page="y.jsp">
   <jsp:param name="param1" value="value1"/>
   <jsp:param name="param2" value="value2"/>
</jsp:include>
...3. for object type information & continous sharing information(main.jsp > x.jsp > main.jsp > y.jsp > main.jsp), u can use request attribute. request attribute is designed for foward & include purpose.
