Re: [docbook-apps] Catalog lookups with openjade on redhat 9.0 withoutnetwork connection fail

[Patrick Eisenacher <eisenacher@fillmore-labs.com>]

Hi Maarten,

your processing tool wants to retrieve the DTD from the address given in 
your document's header: 
http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd

If you want to use your local version, then use an XML catalog to map 
public identifiers to specific locations on your machine. See Bob's 
tutorial on using XML catalogs for all the details involved: 
http://www.sagehill.net/docbookxsl/Catalogs.html. It's pretty easy to 
set up. Best install the XML catalog at the default position 
(/etc/xml/catalog).

HTH,
Patrick
