Severe : Exception. Cannot Load Font. No font URI's available.

[Loran Kary]

I need to be able to use some fonts other than the Base 14 in the  
PDF's I generate.

I have created some font metrics files with TTFReader and in the  
configuration file I specify the font metrics files and the font  
triplets.

If I specify an "embed-url" with the path of the font ttf file, this  
seems to work.  But I don't want to have to embed the fonts in the  
PDF file because they are already installed on my Mac OS X system.  I  
just want to reference those fonts in the PDF file.

Since I have supplied FOP with the font metrics and the font  
triplets, I would expect that FOP has everything it needs to use  
those fonts in the PDF.

But without embedding the font, I get the severe exception, cannot  
load font, and no PDF output.

This is with FOP 0.93 and I understand there may be some known  
problems in this area.  Can anyone tell me more?

Thanks,
