How to get PDF from postscript ?

I did a Google on "java pdf ps", and found this:

It's commercial, but it seems to exist.

I googled on "java pdf ps converter" and found some other stuff, also commercial.

Personally, I'd suggest just Runtime.exec'ing a command-line program...unless you need the platform independence? Actually I think the command-line tools are open source anyway so you could just recompile them for a bunch of platforms.

May I ask why you need to convert PS to PDF from Java only?

Oh, I don't know. It's hard to prove a negative. I've never heard of any open-source project in Java to convert PS to PDF, but there are lots of open-source projects I've never heard of, so who knows? When I went to sourceforge.net and searched on "java pdf ps", there were 14828 results.

Anyway, one way to be sure there's an open-source project to do this, would be to create one. You're free to do so.

However, I'm not sure it's worth the effort. I know that there are postscript and PDF utilities, and I believe converters between the two, available from open source projects and written in C. You can probably compile the source from those on Linux and Windows, and probably OS X, and most major Unix flavors as well, and furthermore they'd be invoked from the command-line the same way.Personally, I'd poke around sourceforge.net or GNU's software directory a bit, and if I can't easily find a Java implementation, just get a well-supported C one.

I'm sure you'll find a converter with a command-line interface. You may find a converter written in C or C++ and compilable on all platforms you need, and that furthermore has a GUI. If not, and if you need a GUI, you can write a GUI in Java, invoking the converter via Runtime.exec (or ProcessBuilder these days) or JNI possibly.
