We don't ever put afp-fonts.xml inside the jar. Rather, we stick it in a
directory called "resources" or some such, and put that directory in the
classpath. For example, our directory structure might look something
like this:

C:\afp
 +- lib
 |   +- afp-renderer.jar
 |   +- fop.jar
 |   +- (more jars)
 +- resources
     +- afp-fonts.xml
     +- afp-font-resources
        +- T1V10285.CDP
        +- C0G21A00.240
        +- (more font resources)

With these directories, we can then start up to renderer using something
like:

java -cp C:/afp/lib/afp-renderer.jar;C:/afp/lib/fop.jar;c:/afp/resources
FO2AFP input.fo output.afp

Looking at the stack trace below, it looks like there has been a problem
reading the code page file (it should be in the classpath). Can you
confirm that you have the file T1V10285.CDP in the classpath?

Cheers,
Joe
