How to create embeded attachment i.e different MIME types in PDF

[developer mania]

Hi,

I'm new to Apache PDFBox.jar

Try to creating PDF which contains embedded attachment as (PDF, images, doc
files, etc...)

Successfully created the plan/text embedded file(s) but failure for other
types.

/*** Sample code tried which add embedded attachment into PDF ***********/

public void doIt( String file) throws IOException
    {
        // the document
        PDDocument doc = null;
        try
        {
            doc = new PDDocument();

            PDPage page = new PDPage();
            doc.addPage( page );
            PDFont font = PDType1Font.HELVETICA_BOLD;

            PDPageContentStream contentStream = new
PDPageContentStream(doc, page);
            contentStream.beginText();
            contentStream.setFont( font, 12 );
            contentStream.newLineAtOffset(100, 700);
            contentStream.showText("Go to Document->File Attachments to
View Embedded Files");
            contentStream.endText();
            contentStream.close();

            //embedded files are stored in a named tree
            PDEmbeddedFilesNameTreeNode efTree = new
PDEmbeddedFilesNameTreeNode();

            try{
            File file1 = new File("/resources/"
                    + "AboutUSHeader.jpg");
            }
            catch (Exception ex){

            }
            //file.

            //first create the file specification, which holds the embedded
file
            PDComplexFileSpecification fs = new
PDComplexFileSpecification();
            fs.setFile( "AboutUSHeader.jpg" );
            //create a dummy file stream, this would probably normally be a
FileInputStream
            //byte[] data = "This is the contents of the embedded
file".getBytes("ISO-8859-1");
            ByteArrayInputStream fakeFile =
                new ByteArrayInputStream( file.getBytes() );
            PDEmbeddedFile ef = new PDEmbeddedFile(doc, fakeFile );
            //now lets some of the optional parameters
            //ef.setSubtype( "test/plain" );
            //ef.setSubtype( "application/pdf" );
            ef.setSubtype( "image/jpg");
            ef.setSize( file.getBytes().length );
            ef.setCreationDate( new GregorianCalendar() );
            fs.setEmbeddedFile( ef );

            // create a new tree node and add the embedded file
            PDEmbeddedFilesNameTreeNode treeNode = new
PDEmbeddedFilesNameTreeNode();
            treeNode.setNames( Collections.singletonMap( "My first
attachment",  fs ) );
            // add the new node as kid to the root node
            List<PDEmbeddedFilesNameTreeNode> kids = new
ArrayList<PDEmbeddedFilesNameTreeNode>();
            kids.add(treeNode);
            efTree.setKids(kids);
            // add the tree to the document catalog
            PDDocumentNameDictionary names = new PDDocumentNameDictionary(
doc.getDocumentCatalog() );
            names.setEmbeddedFiles( efTree );
            doc.getDocumentCatalog().setNames( names );


            doc.save( file );
        }
        finally
        {
            if( doc != null )
            {
                doc.close();
            }
        }
    }


Any suggestion will be helpfull or any alternate way to add embedded
attachments.

Thanks in advance
