 gcj generates code that assumes that the classes your program refers
 to are also compiled.  However, you aren't telling gcj how to link
 against these programs.  Putting the xerces zip file into CLASSPATH is
 necessary, but not sufficient -- the compiled xerces code isn't in the
 zip file.
 
 I recommend compiling all the xerces classes and building a shared
 library named `libxerces.so' from the resulting objects.  Then add
 `-lxerces' to your gcj command.
 
 I'm going to close this PR since I don't believe it is actually a bug.
