publishing javahelp output

I am trying to process javahelp output and was wondering if anyone had suggestions for good tutorials or general advice.  I am using Arbortext Editor and Arbortext Publishing Engine to create the DITA bookmaps and create pdf and webhelp output. Unfortunately, Arbortext doesn't support javahelp builds, so I have downloaded the open toolkit and did the practice javahelp build.   Any suggestions for hooking up Arbortext stylesheets and dtd files with the open toolkit would be much appreciated.  Thanks!
