I've seen this before, and it is just strange.
Once the docbookx.dtd file is found, the references to
dbnotnx.mod etc. are all relative to that file.
The resolver should be able to follow such references,
but it doesn't.  Once the resolver is in use, it
seems every reference must be resolved by a catalog entry,
with the fallback being the raw path to the file
(which is just "dbnotnx.mod" in this case).

You can add a reference to the DTD catalog file in your
main catalog with something like:

<nextCatalog  catalog="file:/home/bburridg/IBM/wsappdev/DocBook/DocBook/catalog.xml"/>
