package pdf;

import org.apache.poi.xwpf.converter.pdf.PdfConverter;

          PdfConverter.getInstance().convert(document,out,options);
        

El siguiente código funcionó para mí:

Public class DocToPdfConverter

public static void main(String[] args) 

        String k=null;
        OutputStream fileForPdf =null;
        try 

            String fileName="/document/test2.doc";
            //Below Code is for .doc file 
            if(fileName.endsWith(".doc"))
            
            HWPFDocument doc = new HWPFDocument(new FileInputStream(
                    fileName));
            WordExtractor we=new WordExtractor(doc);
            k = we.getText();

             fileForPdf = new FileOutputStream(new File(
                        "/document/DocToPdf.pdf")); 
            we.close();
            

            //Below Code for 

            else if(fileName.endsWith(".docx"))
            
                XWPFDocument docx = new XWPFDocument(new FileInputStream(
                        fileName));
                // using XWPFWordExtractor Class
                XWPFWordExtractor we = new XWPFWordExtractor(docx);
                 k = we.getText();

                 fileForPdf = new FileOutputStream(new File(
                            "/document/DocxToPdf.pdf"));    
                 we.close();
            



            Document document = new Document();
            PdfWriter.getInstance(document, fileForPdf);

            document.open();

            document.add(new Paragraph(k));

            document.close();
            fileForPdf.close();



         catch (Exception e) 
            e.printStackTrace();
