On the same machine where the server runs?

Some possiblities:
- very old parser or a parser with a specific problem in
   the classpath
- encoding problems
- lack of karma.

Upgrade your Tomcat and make sure to use a recent parser
(e.g Xerces 2.x). If the problem persists check whether
the encoding in the XML declaration matches the actual
encoding. Run a validation on the file on the server
machine.

BTW this is not a FOP problem.

This problem could be caused by a number of reasons. How
did you embed FOP? Do you feed it from a file? Does this
file work with the command line FOP application?

In any case, you should upgrade to TC 4.0.4 and the latest
FOP distribution.
