Running the build with IBM Java 1.4.2 fails - xerces issue with XInclude.
Please use Java 5.0 or later.

To get the images into the PDF output, you must have the "Java Advanced
Imaging" Library from Sun.  The tooling will obtain this for you the 
first time it is run, 
but your Company may have other places than "Sun" to obtain this library
from, perhaps under alternative licensing arrangements.  
If so, you can obtain the library from those places, unzip the archive, and put the two files:
   jai_codec.jar   and jai_core.jar
in the uima-docbook-tool project, under tools/jai-versions/jai-1.1.3/
