Looking for options: PDF to PS conversion

Hi all,

I need to know what options might be available for a document conversion 
utility to render PDF into PostScript.  I had planned to make use of PASE and 
Ghostscript (as AIX binaries) to accomplish this, but such a solution affords 
little support, and I've been instructed to look for vendor offerings.  

I'd prefer to NOT use an external server to handle the conversion, doing this 
on iSeries natively, but I will consider all options at this point.  I 
originally thought this could be done easily in Java, but I could not find any 
good examples to work with.  

Thanks in advance for all suggestions.

Eric
