Programatically Convert to PDF Photoshop(.psd), Illustrator(.ai), and InDesign(.indd) possible?

Hey,

I'm just wondering if there is an Adobe product or and kind of way to programatically convert Photoshop(.psd), Illustrator(.ai), and InDesign(.indd) files to a PDF using a programming langauge like Java? I've had a look at Livecycle and it doesn't seem to convert Illustrator or InDesign files and it would be a bit bloated to download the whole LiveCycle modules when I'm only interested in the PDF conversion module.

Any direction to an Adobe product or another solution would be much appreciated.

Thanks
