DOCBOOK-APPS: missing some java classes running FOP

["Robert P. J. Day" <rpjday at mindspring dot com>]

  i downloaded the latest FOP from xml.apache.org, and installed
what i thought was everything i needed around it (Jimi, the newer
xalan in the endorsed/ directory and so on), but when i run FOP
to convert a .fo file to .pdf, i get:

[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2 Parser
[INFO] FOP 0.20.5rc2
