I am trying to attach a file to a existing PDFA-3. This example explains how to create a PDFA-3 and attach content to it. My next step was to adapt the code and use the PdfAStamper instead of the document. So here is my resulting code. private ByteArrayOutputStream append(byte content, InputStream inPdf) throws IOException, DocumentException ByteArrayOutputStream result = new ByteArrayOutputStream(16000); PdfReader reader = new PdfReader(inPdf); PdfAStamper stamper = new PdfAStamper(reader, result, PdfAConformanceLevel.PDF_A_3B); stamper.createXmpMetadata(); Creating PDFA-3 compliant attachment. PdfDictionary embeddedFileParams = new PdfDictionary(); embeddedFileParams.put(PARAMS, new PdfName(ZF_NAME)); embeddedFileParams.put(MODDATE, new PdfDate()); PdfFileSpecification fs = PdfFileSpecification.fileEmbedded(stamper.getWriter(), null,ZF_NAME, content , textxml, embeddedFileParams,0); fs.put(AFRELATIONSHIP, Alternative); stamper.addFileAttachment(file description,fs); stamper.close(); reader.close(); return result; Here is the Stacktrace of the error. com.itextpdf.text.pdf.PdfAConformanceException: EF key of the file specification dictionary for an embedded file shall contain dictionary with valid F key. at com.itextpdf.text.pdf.internal.PdfA3Checker.checkFileSpec(PdfA3Checker.java:95) at com.itextpdf.text.pdf.internal.PdfAChecker.checkPdfAConformance(PdfAChecker.java:198) at com.itextpdf.text.pdf.internal.PdfAConformanceImp.checkPdfIsoConformance(PdfAConformanceImp.java:70) at com.itextpdf.text.pdf.PdfWriter.checkPdfIsoConformance(PdfWriter.java:3380) at com.itextpdf.text.pdf.PdfWriter.checkPdfIsoConformance(PdfWriter.java:3376) at com.itextpdf.text.pdf.PdfFileSpecification.toPdf(PdfFileSpecification.java:309) at com.itextpdf.text.pdf.PdfIndirectObject.writeTo(PdfIndirectObject.java:157) at com.itextpdf.text.pdf.PdfWriter$PdfBody.write(PdfWriter.java:424) at com.itextpdf.text.pdf.PdfWriter$PdfBody.add(PdfWriter.java:402) at com.itextpdf.text.pdf.PdfWriter$PdfBody.add(PdfWriter.java:381) at com.itextpdf.text.pdf.PdfWriter$PdfBody.add(PdfWriter.java:334) at com.itextpdf.text.pdf.PdfWriter.addToBody(PdfWriter.java:819) at com.itextpdf.text.pdf.PdfFileSpecification.getReference(PdfFileSpecification.java:256) at com.itextpdf.text.pdf.PdfDocument.addFileAttachment(PdfDocument.java:2253) at com.itextpdf.text.pdf.PdfWriter.addFileAttachment(PdfWriter.java:1714) at com.itextpdf.text.pdf.PdfStamper.addFileAttachment(PdfStamper.java:497) Now when I try to analyze the Stacktrace and take a look atPdfFileSpecification.fileEmbeddedI see that an EF is created with an F and UF entry. Looking inside PdfA3Checker I see that line PdfDictionary embeddedFile = getDirectDictionary(dict.get(PdfName.F)); is not a directory but a strem. if (fileSpec.contains(PdfName.EF)) PdfDictionary dict = getDirectDictionary(fileSpec.get(PdfName.EF)); if (dict == null || !dict.contains(PdfName.F)) throw new PdfAConformanceException(obj1, MessageLocalization.getComposedMessage(ef.key.of.file.specification.dictionary.shall.contain.dictionary.with.valid.f.key)); PdfDictionary embeddedFile = getDirectDictionary(dict.get(PdfName.F)); if (embeddedFile == null) throw new PdfAConformanceException(obj1, MessageLocalization.getComposedMessage(ef.key.of.file.specification.dictionary.shall.contain.dictionary.with.valid.f.key)); checkEmbeddedFile(embeddedFile); Is this a bug in iText or am I missing something? By the way I am using iText 5.4.5. Update 1 As suggested by Bruno an mkl the 4.5.6-Snapshot should contains the fix. I tried my Test case Gist link to full test case against the current trunk. But the result was the same error. View Discussion Improve Article Save Article Like Article Read Discuss View Discussion Improve Article Save Article Like Article iText is a Java library developed, to access and manipulate PDF files, that is to extract and modify the PDF content. iText is a Java library originally created by Bruno Lowagie which allows creating, reading, and manipulating PDF files. Java allows incorporating various fully developed packages and modules in order to work with PDF files.iText library enables the creation of a PDF document in the local directory and adding contents to the PDF file created using the java program. Here, formatting the contents of a table cell in a PDF using java can be achieved below mentioned in the article.Libraries required: iTextslf4j (Logging Library) Procedure:Download the iText jar files.Download the slf4j jar file.To use the libraries add the above-downloaded jar files to the classpath of the system.Get the current working directory of the running java program to create the PDF file in the same location.Create a PdfWriter object (from itextpdf library) which writes the PDF file to the given path.Create an empty PDF Document object.Create a Table using a Table object and set Table Dimensions.Create Cells and add attributes to cell-like Text Alignment, Font Color, Background Color & Cell Content.Add the Cells to the Table.Sample Input Image: This PDF file input image is used the below program to format the content of the cell.Implementation: First cells are created in the above input PDF file and then the content of the cell is formattedExample import java.io.*; import com.itextpdf.kernel.colors.*;import com.itextpdf.kernel.pdf.PdfDocument;import com.itextpdf.kernel.pdf.PdfWriter;import com.itextpdf.layout.Document;import com.itextpdf.layout.element.Cell;import com.itextpdf.layout.element.Paragraph;import com.itextpdf.layout.element.Table;import com.itextpdf.layout.property.TextAlignment; public class FormatCellPdf public static void main(String args) throws Exception String path = System.getProperty(user.dir); path += cellPDF.pdf; PdfWriter writer = new PdfWriter(path); PdfDocument pdfDoc = new PdfDocument(writer); Document doc = new Document(pdfDoc); float columnWidhts = 300F, 300F ; Table table = new Table(columnWidhts); Cell cell1 = new Cell(); cell1.add(new Paragraph(Color).setFontColor( ColorConstants.WHITE)); cell1.setBackgroundColor(ColorConstants.BLACK); cell1.setTextAlignment(TextAlignment.CENTER); Cell cell2 = new Cell(); cell2.add(new Paragraph(Black).setFontColor( ColorConstants.WHITE)); cell2.setBackgroundColor(ColorConstants.BLUE); cell2.setTextAlignment(TextAlignment.CENTER); Cell cell3 = new Cell(); cell3.add(new Paragraph(Color).setFontColor( ColorConstants.WHITE)); cell3.setBackgroundColor(ColorConstants.BLUE); cell3.setTextAlignment(TextAlignment.CENTER); Cell cell4 = new Cell(); cell4.add(new Paragraph(Red).setFontColor( ColorConstants.WHITE)); cell4.setBackgroundColor(ColorConstants.BLACK); cell4.setTextAlignment(TextAlignment.CENTER); Cell cell5 = new Cell(); cell5.add(new Paragraph(Color).setFontColor( ColorConstants.WHITE)); cell5.setBackgroundColor(ColorConstants.BLACK); cell5.setTextAlignment(TextAlignment.CENTER); Cell cell6 = new Cell(); cell6.add(new Paragraph(Yellow).setFontColor( ColorConstants.WHITE)); cell6.setBackgroundColor(ColorConstants.BLUE); cell6.setTextAlignment(TextAlignment.CENTER); table.addCell(cell1); table.addCell(cell2); table.addCell(cell3); table.addCell(cell4); table.addCell(cell5); table.addCell(cell6); doc.add(table); doc.close(); System.out.println(Table created successfully!); Output: In console window message is printed Table successfully created to show proper execution of program and changes made during execution in input file during execution is as shown.
