Okay (wasn't sure which list before).

Okay.  According to that error message, that the file named

/sw/share/sgml/dsssl/docbook-dsssl-nwalsh/print/docbook.dsl

contains the following line

<!DOCTYPE style-sheet PUBLIC "-//James Clark//DTD DSSSL Style 
Sheet//EN" [

and that OpenJade wants to know how to resolve this public identifier 
into a SYSTEM file.  This is my best guess.  The problem is that I am 
unsure of what I should do -- there is a catalog file already present in 
the same directory as "docbook.dsl", but unfortunately it doesn't map 
this PUBLIC identifier to anything.

Should I manually add a line to the catalog file that does a mapping 
here?  And if so, what file on my SYSTEM should I map this PUBLIC 
identifier to?


I think I'm making some progress here, and I really appreciate 
everyone's help.
