Matthew- I just finished doing this on a Windows box also, and I believe your problem is that the JVM can't find the files for the TTFReader class. You can include class paths by using the -cp command line option. Take a look at the actual fop.bat that came in the distribution, and make sure you include those class paths with your call to the TTFReader class.
Hope that helps. If not, let me know. P.S. This is my first post to this group (actually my first post to any group) using this e-mail client. All apologies for screwy formatting. -Jeff Mitchell "Matthew Huggett" To: <[EMAIL PROTECTED]> <[EMAIL PROTECTED] cc: lanet.net> Subject: fonts 04/30/2002 11:19 PM Please respond to fop-user Hi: I'm trying to create a few font metrics files. Here's the command I'm using: C:\Program Files\FOP\fop-0.20.3>java org.apache.fop.fonts.apps.TTFReader -ttcname "HGRM" C: \Windows\Fonts\HGRM.TTC hgrm.xml And this is the error message I get: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/fop/fonts/apps/TTFReader I don't know s**t about Java programming but I guess this means that my command wasn't good or I'm missing something. How do I fix this? Thanks Matthew
