JSP :: JSTL Import Not Working?

I have the following data in a file called books.xml in my WEB-INF folder:

<?xml version="1.0"?>
<books>
<book>
<name>Padam History</name>

[Code] ....

I'm using the following code in a jsp:

<c:import var="bookInfo" url="/WEB-INF/books.xml" />

I know that it's finding the file because if I delete books.xml from the WEB-INF folder I get a FileNotFound exception.

However, for some reason it doesn't appear to be importing the data into the bookInfo variable.

I noticed this problem because when I try to parse it via:

<x:parse xml="${bookInfo}" var="output"/>

I get org.xml.sax.SAXParseException: Premature end of file.

When I try to display the data in the variable either by:

<c:out value="${bookInfo}" />

...or by means of a scriptlet (which I realize is not a best practice):

<%
String myVariable = (String)pageContext.getAttribute("bookInfo");
System.out.print("bookInfo=" + myVariable);
%>

...I get nothing.

BTW when I do:

<c:import var="data" url="http://www.tutorialspoint.com"/>
<c:out value="${data}"/>

that works fine!
