Hi, I'm trying out the editor and tried to use a custom XML Catalog for my project. Below is the catalog that i've careated: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE catalog PUBLIC "-//OASIS//DTD XML Catalogs V1.1//EN" "http://www.oasis-open.org/committees/entity/release/1.1/catalog.dtd"> <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> <systemSuffix systemIdSuffix="DTD_LG_XMLV24.DTD" uri="file:///D:/RND/Hachette/DTD/DTD_LG_XMLV24.DTD"/> <uriSuffix uriSuffix="DTD_LG_XMLV24.DTD" uri="file:///D:/RND/Hachette/DTD/DTD_LG_XMLV24.DTD"/> </catalog> I'm not familiar with catalogs so please bear with me. From my understanding this catalog will resolve my DOCTYPE declarations to find a local copy of my DTD. So if I have a <!DOCTYPE livre SYSTEM "DTD_LG_XMLV24.DTD"> in my declaration this will eventually map-out to file:///D:/RND/Hachette/DTD/DTD_LG_XMLV24.DTD. Right? I have added this catalog in the XML Catalog section in the preferences and already restarted the editor, but upon validation I still get a FileNotFoundException-D:\RND\Hachette\DTD_LG_XMLV24.DTD (The system cannot find the file specified). What am I doing wrong here? Thanks, Jeff Sese -- *Jeferson L. Sese* Asiatype Incorporated Suite 114, Columbia Tower, Ortigas Ave., Greenhills, Mandaluyong City 1550 Philippines
