More questions RE: running FOP headless

[Clay Leeds <cl...@medata.com>]

One of my colleagues is working on modifying FOP to output to multi-page 
TIFF (& got it working!). The coding is similar to Oleg's TiffRenderer. 
Unfortunately, we're running up against 'headless' issues 
(http://xml.apache.org/fop/graphics.html#batik).

My client is running fop-0.20.4 on AIX 4.3 with JRE 1.3 (IBM). 
Apparently, 1.3 is the latest version of JRE available for AIX 4.3, so 
we can't do the '-Djava.awt.headless=true' command line option. We've 
also tried the other avenues indicated in the Batik section of 
FOP/graphics. We've also tried into installing some funky AWT 
implementation which doesn't require X server. But fonts aren't working 
(yet).

In addition, we've tried outputting to -ps (works *great* on AIX 4.3 
btw), and then converting to TIFF using ImageMagick, but there are 
numerous problems there (binaries break under AIX, source doesn't 
compile w/o significant mods to header vars & macros).

Essentially what we want, is to be able to do use FOP to -print under 
Java 1.3, without requiring an X-server.

Any ideas?

FWIW, here's the e-mail I received from my colleague RE: the problems 
we're having.
