DTD definition in XML

Question

DTD is valid. DTD and XML are in the same directory.
I can read from XML, when is validation off.
When is validation on, it is throwing exception...
Project path: d:/dbt
Path to xml is: /files/xml
In XML file :
<!DOCTYPE ABCD SYSTEM "dictionary.dtd">
<ABCD>
<JKL>
</JKL>
</ABCD>
JavaException:
org.jdom.JDOMException: Error on line 1: Relative URI "dictionary.dtd"; can not be resolved without a base URI.
Thanx.

Answer 1

I implemented the exemple, bt I have another problem.
My DTD includes other DTD and I have the same error for the others DTD.
JavaException:
org.jdom.JDOMException: Error on line 4: Relative URI "./geographie_mcto.dtd"; can not be resolved without a base URI.
Following the beginning of the DTD :
<?xml version="1.0" encoding="UTF-8"?>
<!ENTITY % Booleen "(oui|non) 'non'">
<!ENTITY % Numerique "#PCDATA">
<!ENTITY % Geographie SYSTEM './geographie_mcto.dtd'>
%Geographie;
<!ENTITY % Date_heure SYSTEM './date_heure.dtd'>
%Date_heure;
