This question is from HFSJ page 424.
Question: The following code fragment appears in a JSP page:
<jsp:include page="/jspf/header.html" />
The JSP page is part of a web application with the context root myapp.
Given that the application's top level directory is myapp, what is the path to the header.html file?

A. /header.html
B. /jspf/header.html
C. /myapp/jspf/header.html ....according to the book - correct answer.
D. /includes/jspf/header.html

What I don't understand is the question itself. When it says "what is the path ...", my question is related to what? the server root? or as it would be identified in <location> as defined in web.xml (then the correct answer would be B not C).
Thus, what is the context of the question? or am I missing something that is obvious?

Thanks.

I think the question is just asking what is the path as in the "file path"

If a back slash is present it is considered relative to the current context root. Here the current context root is "myapp"

The server interprets a relative URL relative to the current directory. Here the current directory is "/jspf/header.jsp"

<jsp:include page="/jspf/header.jsp" />

And final answer is:
<%-- Includes: /myapp/jspf/header.jsp --%>

If the relative URL starts with /, the path is relative to the JSP application's context, If the relative URL starts with a directory or file name, the path is relative to the JSP page.
 
Don't get me started about those stupid light bulbs.
