Supporting DocBook olink in Maven Project

Question

I introduced my current project at work to DocBook for creating our user's guide. We have now split into two separate documents and I'm trying to get cross-linking between the documents working. I've got the .db files being generated now. But in doing so the html files no longer have any content (I've disabled pdf until I can get the html working). The generated xml files seem to be complete, they're just not getting transformed into html. Any help would be greatly appreciated.
