(Using Oxygen 11, Eclipse plugin version, on Ubuntu 9.10, with output to Eclipse Help.) I'm trying to speed up processing by pointing to the catalog file, but it seems clear that the processor is instead going to the OASIS site. I noticed this when I suddenly started getting 403 errors from the OASIS site. Here's some OT processor output that seems to confirm my suspicion: [pipeline] [DOTJ013E][ERROR] Failed to parse the referenced file 'reference/api_cubitmethods.xml' due to below exception. Please correct the reference base on the exception message. [pipeline] Server returned HTTP response code: 403 for URL: http://docs.oasis-open.org/dita/v1.1/OS/dtd/reference.dtd Here's the catalog entry that I think should tell the processor to use the local resource before going to the OASIS site. This is copied from /com.oxygenxml.author_11.0.0/frameworks/dita/DITA-OT/catalog-dita.xml <public publicId="-//OASIS//DTD DITA Reference//EN" uri="reference.dtd"/> <public publicId="-//OASIS//DTD DITA 1.x Reference//EN" uri="reference.dtd"/> <public publicId="-//OASIS//DTD DITA 1.2 Reference//EN" uri="reference.dtd"/> And here is the setting in Preferences > Author > XML > XML Catalog that, as I understand it, points the processor to the local copy of the DTD rather than the OASIS copy: ${frameworks}/dita/catalog.xml So (leaving aside for the moment the question of why I suddenly started getting 4.3 errors from the OASIS site), what setting have I set incorrectly and how can I get the processor to use the local copy of the DTDs?
