C++/Java Postscript Libraries?

myrkul asks: "I'm working on an application that takes vector graphics, text, and bitmapped pictures as well as layout info from a database, and converts it to postscript (PDF would work too) for printing. I've been looking for (preferably free) Postscript libraries for either C++ or Java which would allow me to lay out these elements, and haven't had much luck. Any suggestions?"
