If you add a catalog file to Preferences / XML / XML Catalog or you change a catalog file referenced from a file added there you have to reopen the transformed XML or XSLT file in Oxygen if it is already opened or you have to restart Oxygen. But in your case I understand that you tried to use the rewriteURI mapping from frameworks/docbook/catalog.xml which should work out of the box as it is one of the Oxygen default catalogs. If you can reproduce the error again please let us know. Thank you, Sorin Florent Georges wrote:

The catalog in the DocBook framework contains the following entry:
<rewriteURI
uriStartString="http://docbook.sourceforge.net/release/xsl/current/" rewritePrefix="xsl/"/>
So if I am right that's correct, isn't it?
Mmh, I stopped oXygen and restarted it. And now it does use the catalogs to resolve the stylesheet URI. Maybe I've just hit a corner case somewhere...
