Sample test case : Unresolved entities in included JSP file

Ludovic Maitre Mon, 20 Jan 2003 04:48:44 -0800

Hello,
My first mail wasn't very clear, a simple test case follow.

Sample test case
----------------


File test_include.jsp :
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE toto [
	<!ENTITY nbsp  "&#160;">
]>

<jsp:root
	xmlns:jsp="http://java.sun.com/JSP/Page";
	version="1.2">
<div>
    <p>&nbsp;</p>
	<jsp:directive.include file="test_included.jsp"/>
</div>
</jsp:root>

File test_included.jsp :
<p>&nbsp;</p>

When i access to test_include.jsp :

XML Parsing Error: undefined entity
Location: http://localhost:8080/test_include.jsp
Line Number 1, Column 17:
<div><p> </p><p>&nbsp;</p></div>
----------------^

If somebody has an idea thanks per advance.
Regards,
Ludo

Hello,

I have a JSP 1.2 page who include some french character like ô .

The problem is that i have added the entity ocirc; to the dtd of my JSP and it seems that the DTD doesn't apply to the JSP files included from this page.

I have the following pages :
index.jsp
recherche.jsp

My index.jsp page is written in JSP 1.2 with XML syntax and include a declaration of the JSP1.2 DTD :
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE root PUBLIC "-//Sun Microsystems Inc.//DTD JavaServer Pages Version 1.2//EN"
"http://localhost:8080/awrgfa/dtd/jspxml.dtd";>

The JSP 1.2 DTD come from the website of Sun (it's annotated "DTD for JSP 1.2 thanks to Bob Foster, WebGain") and i use a modified version locally who include the following last lines :
<!ENTITY % ISOLat1 SYSTEM "http://localhost:8080/awrgfa/dtd/latin1.dtd"; >
%ISOLat1;

the file latin1.dtd contain lines like :

<!ENTITY ocirc "ô">

(the normative syntax, used on the W3C website, is :<!ENTITY ocirc CDATA "ô">. It doesn't work and trigger :

org.apache.jasper.JasperException: http://localhost:8080/awrgfa/dtd/latin1.dtd(12,18) OpenQuoteMissingInDecl

I don't know why, i think it concern the people of Xerces)

So after this little work, my JSP page can contain HTML entities references like ô.

The problem is that i include the menu to the JSP page with an include directive in index.jsp :
<jsp:root
xmlns:jsp="http://java.sun.com/JSP/Page";
version="1.2">

<html xmlns="http://www.w3.org/1999/xhtml";>

<head><title>Hôtes</head>

<body link="#000000" vlink="#333333" alink="#000000" leftmargin="0" topmargin="0">
...
<jsp:directive.include file="/pages/menu.jsp"/>
...
</body>
</html>
</jsp:root>

The file /pages/menu.jsp is only a fragment of XHTML, he has a reference to the entity icirc; :
<form>
...
<option>Hôtes</option>
...
</form>

The problem is that this entity is unresolved at compilation :

XML Parsing Error: undefined entity
Location: http://localhost:8080/awrgfa/pages/modele.jsp
Line Number 10, Column 37: <option>Hôtes</option>
------------------------------------^

So my questions are :
1 - why the DTD defined in the document who include the others isn't applicable to the included documents ?
2 - Who is responsible for this bug (if this is a bug) : Xerces ? Jasper ? Me ?

So thanks per advance for any answer and best regards,
