Adobe seems to have a library. Here are some instructions. Please note, I have not tried this myself: http://help.adobe.com/en_US/livecycle/9.0/programLC/help/index.htm?content=000761.html

You can use PDFDocument to load your PDF then use PSConverter to convert the PDF document into an OutputStream.

The library I'm using is called ghost4j :

import org.ghost4j.converter.PSConverter; 
import org.ghost4j.document.PDFDocument;

Here's a small snippet:

private ByteArrayOutputStream convertPDFtoPS(){

    ByteArrayOutputStream  outstreamFile = new ByteArrayOutputStream();

    try{            
        PDFDocument document = new PDFDocument();
        //getPDFFile just returns an InputStream of the PDF file
        document.load(getPDFFile());           
        PSConverter converter = new PSConverter();
        converter.convert(document, outstreamFile); 

        outstreamFile.close();
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

    return outstreamFile;    
}
