IText (Java2PDF) problem

Maby this isnt the right place for this quesstion but...
I have a very strange problem.
I'm using a servlet to generate PDF file on the web with iText...
The Application Server is runing on WebSphere 6 ND and has 2 network cards..
One is for the local network and the other goes into a Cisco routher..
The users in the local network can print and view the PDF without any problems,
but everyone who logins into the system throw the routher cannot view or print PDF's.
The big question is does anybody knows what port is the iText using to send the data for the PDF on web.
my application is set at port 9080
tnx

Hello All ,
i found the root cause for the above problem....
please help me out...
when i write the code like :
pdfReader = new PdfReader(baos.toByteArray());
writer.addPage(writer.getImportedPage(pdfReader, 2));
writer.addPage(writer.getImportedPage(pdfReader, 1));i can check/uncheck the radio buttons which is in page number 2 and now the page 1 is read only,but when i write
pdfReader = new PdfReader(baos.toByteArray());
writer.addPage(writer.getImportedPage(pdfReader, 1));
writer.addPage(writer.getImportedPage(pdfReader, 2));Now on the page 1 read/write but page 2 i can not.
Any suggestions would be appreciated...
thanks in advance

Problem in merging large collection of PDF in single pdf at a time-itext

hi
i am using itext library for PDF generation.My problem is ,when i merge the large number of PDFs which is already
generated, in a single PDF ,i got 'Out of Memery' exceptions,but when i doing this with limited number of PDFs
they are concated as a single PDF .so what shall i do to overcome Out of memory exceptions.because,our client wants to print the mass PDF ,which may have more than 1000 PDFs on a single merged PDF .if any possible,when i merge the single PDF with already merged PDF one by one at a time when it will be generated,how can i handle I/O streams to open one PDF at a time and merge with already generated PDF on the same time,and how can i append the generating PDF directly on already generated PDF using streams

thanks for your reply,
i already tried open and close the output stream and Input Stream to read and write every PDF,but i conflicted that that last PDF only is written in the final merged PDF.so what can i do to this every time the new PDF is to take to merge with already merged PDF.
i want know about CODE TAGS
As per your succession,
for(int i =0 ;i<200;i++){
               output = new FileOutputStream("E:\\templates\\out\\Merged PDF\\merge.pdf",true);
               document.open();
               String value     = "E:\\templates\\out\\07J439HF_FINAL_EVALU.pdf";
               ConcatPDFs.concatPDFs(document,writer,value, true);
               output.flush();
               document.close();
               output.close();
thanks

Problem in opening PDF files using Reader 8 when created with iText 2.1.3

We are facing problem in using IText version 2.1.3. We are using Acrobat Reader 8.1 for viewing the PDF documents. In our Shell program we are splitting and merging the pdf documents using IText. The pdf document works correctly and is readable for documents with one page while it fails for documents with multiple pages.Also please note that it works fine with the older Arcobat reader version say version 7.0 and below but since business has migrated to acrobat higher version we expect IText to work in sync.
We have already raised a bug with the iText and got the information from them stating that the problem is due to the over nesting of XObjects, which has a threshold value of 50 and was discarded in earlier versions but got flagged in Acrobad Reader 8. Also note that we have reported a bug with the adobe development team.
We tried working with other Java PDF tools (jPDFProces), to manupulate the pdf files but were facing the same problem. Hence we understand that the problem is with Adobe Reader 8 as the manupulated pages are being viewed in Adobe Reader 7, but fails to read in Adobe Reader 8.
Kindly provide us with a solution.
Thanks and Regards,

Buon Giorno
Ho un problema riguardo Adobe Reader.
La vecchia versione Adobe 8.1.1 non mi apre più i files in formato PDF.
Ho provato ad installare l'ultima versione Adobe 9 , arriva fino ad un passo dal completamento ma non riesce a terminare. mi da il seguente errore:
ERROR 1714 The older version of Adobe Reader 9 cannot be removed.
Contattare l'assistenza!
Ho cancellato tutti i riferimenti Adobe dal DeskTop, dal Pannello di Controllo e dal FILES Programmi, ma niente!
Vi sarei grato se potete mandarmi un dettagliato help per riuscire a completare l'installazione.
Grazie

Problem signing PDF from smart card - BouncyCastle, IAIK Wrapper, iText

Hello!
I need to sign and timestamp a PDF document with a smartcard. I'm using Java 1.6, iText to manage PDF, BouncyCastle to deal with cryptography and the free IAIK WRAPPER to access the smartcard.
I've already searched the Internet to solve my problem, read the PDF specifications about the signature and followed snippets that should've worked, but after a couple of weeks I still don't have working code, not even for the signature. All the tries I made yield messages like "Signature has been corrupted" or "Invalid signature" (I can't remember the exact messages, but they're not in English anyway :D ) when I verify the signature in Adobe Reader.
My first goal was to use an encapsulated signature, using filter Adobe.PPKLITE, subfilter adbe.pkcs7.sha1 and a DER-Encoded PKCS#7 object as content.
Among the tries I made, I used code such as (I don't include all modifications, just the ones I deem closer to the right approach):
     // COMMON - START
     ///// selectedKey is a iaik.pkcs.pkcs11.objects.Key instance of the private key I'm taking from the SC
     RSAPrivateKey signerPrivKey=(RSAPrivateKey)selectedKey;
     CertificateFactory certificateFactory=CertificateFactory.getInstance("X.509");
     ///// correspondingCertificate is a iaik.pkcs.pkcs11.objects.X509PublicKeyCertificate instance of the certificate I'm taking from the SC
     byte[] derEncodedCertificate=correspondingCertificate.getValue().getByteArrayValue();
     X509Certificate signerCert=(X509Certificate)certificateFactory.generateCertificate(new ByteArrayInputStream(derEncodedCertificate));
     Provider provider=new BouncyCastleProvider();
     Security.addProvider(provider);
     ///// session is an instance of iaik.pkcs.pkcs11.Session
     session.signInit(Mechanism.SHA1_RSA_PKCS, signerPrivKey);
     File theFile = new File("C:\\toSign.pdf");
     FileInputStream fis = new FileInputStream(theFile);
     byte[] contentData = new byte[(int) theFile.length()];
     fis.read(contentData);
     fis.close();
     PdfReader reader = new PdfReader(contentData);
     ByteArrayOutputStream baos = new ByteArrayOutputStream();
     PdfStamper stp = PdfStamper.createSignature(reader, baos, '\0');
     PdfSignatureAppearance sap = stp.getSignatureAppearance();
     // COMMON - END
     java.security.cert.X509Certificate[] certs=new java.security.cert.X509Certificate[1];
     CertificateFactory factory=CertificateFactory.getInstance("X.509");
     certs[0]=(X509Certificate)factory.generateCertificate(new ByteArrayInputStream(correspondingCertificate.getValue().getByteArrayValue()));

     dic.setDate(new PdfDate(sap.getSignDate()));
     dic.setName(PdfPKCS7.getSubjectFields((X509Certificate)certs[0]).getField("CN"));
     sap.setCryptoDictionary(dic);
     int csize = 4000;
     HashMap exc = new HashMap();
     exc.put(PdfName.CONTENTS, new Integer(csize * 2 + 2));
     sap.preClose(exc);
     MessageDigest md = MessageDigest.getInstance("SHA1");
     InputStream s = sap.getRangeStream();
     int read = 0;
     byte[] buff = new byte[8192];
     while ((read = s.read(buff, 0, 8192)) > 0)
          md.update(buff, 0, read);
     byte[] signature=session.sign(buff);
     CMSSignedDataGenerator generator = new CMSSignedDataGenerator();
     ArrayList list = new ArrayList();
     for (int i = 0; i < certs.length; i++)
          list.add(certs);
     CertStore chainStore = CertStore.getInstance("Collection", new CollectionCertStoreParameters(list), provider);
     generator.addCertificatesAndCRLs(chainStore);
     CMSProcessable content = new CMSProcessableByteArray(md.digest());
     CMSSignedData signedData = generator.generate(CMSSignedDataGenerator.ENCRYPTION_RSA, content, true, provider);
     byte[] pk = signedData.getEncoded();
     byte[] outc = new byte[csize];
     PdfDictionary dic2 = new PdfDictionary();
     System.arraycopy(pk, 0, outc, 0, pk.length);
     dic2.put(PdfName.CONTENTS, new PdfString(outc).setHexWriting(true));
     sap.close(dic2);
     File newOne = new File("C:\\signed.pdf");
     FileOutputStream fos = new FileOutputStream(newOne);
     fos.write(baos.toByteArray());
     fos.close();
I figured this is the right approach, but I need a way to generate the CMSSignedData instance, which can't be done using addSigner (the only documented way I found), since the private key is not extractable from a smart card...
Then I decided to give up and try with a detached signature:
     // COMMON - START
     // Same as above
     // COMMON - END
     sap.setSignDate(new GregorianCalendar());
     java.security.cert.X509Certificate[] certs=new java.security.cert.X509Certificate[1];

     sap.setExternalDigest (new byte[8192], new byte[20], "RSA");
     sap.preClose();
     MessageDigest messageDigest = MessageDigest.getInstance ("SHA1");
     byte buff[] = new byte[8192];
     int n;
     InputStream inp = sap.getRangeStream ();
     while ((n = inp.read (buff)) > 0)
          messageDigest.update (buff, 0, n);
     byte hash[] = messageDigest.digest();
     byte[] signature=session.sign(hash);
     PdfSigGenericPKCS sg = sap.getSigStandard ();
     PdfLiteral slit = (PdfLiteral)sg.get (PdfName.CONTENTS);
     byte[] outc = new byte[(slit.getPosLength () - 2) / 2];
     PdfPKCS7 sig = sg.getSigner ();
     sig.setExternalDigest (session.sign(hash), hash, "RSA");
     PdfDictionary dic = new PdfDictionary ();
     byte[] ssig = sig.getEncodedPKCS7();
     System.arraycopy (ssig, 0, outc, 0, ssig.length);
     dic.put (PdfName.CONTENTS, new PdfString (outc).setHexWriting(true));
     sap.close (dic);
     File newOne = new File("C:\\signed.pdf");
     FileOutputStream fos = new FileOutputStream(newOne);
     fos.write(baos.toByteArray());
     fos.close();
I'm still stuck to the signature process, can anyone please tell me what I'm doing wrong and help me (snippets would be deeply appreciated), maybe even changing approach in order to be able to add a digital timestamp?
Thank you very much in advance!
PS: I had also tried to use the SunPKCS11 provider to access the smart card, I gave up for similar problems, but if someone has suggestions using it, they're welcome! :D

Problem with iText pageEvent.

I am creating a PDF document using iText and writing some tables to it.
On page end event of PDFWriter I am creating footer. method :onEndPage(PdfWriter pdfwriter, Document document)
My problem is that this event is getting called twice.
so some tables are cut even if whole page is available and they are being written to new page.
Can anybody pls help me why this happens.?

Srikant,
If the code compiled OK and failed with this error at runtime then perhaps the JAR file containing com.trend.iwss.jscan.appscan.runtime.PolicyProps Class is older than the one you compiled the code with.
You could locate the .JAR file using the Class Finder tool, and deploy it as part of your code as a library.
Cheers,
Steve

Problem while generating PDF using iText

Hi:
I have generated PDF using iText, where i have written all code in sequential flow.
<code>
com.lowagie.text.Document document = new com.lowagie.text.Document(PageSize.A4, 55, 5, 20, 20);
OutputStream outputstream = response.getOutputStream();
PdfWriter.getInstance(document,outputstream);
</code>
And i have added all fields in the document.
But my problem is how to display total pagecount on all pages e.g.1\20 (because i have generated PDF sequentially)
Also i want to add watermark on all pages.
So, can any body help me to solve this problem?
Thank You,
Balaji

Problem while rendering report generated with iText API

Hi!
I am stuck with problem of rendering report generated through iText API.
What exactly happens is, I have to put an image (.jpg) on my report, when I am generating HTML file using iText API, the image size is normal i.e., as it is taken.
But when I render it to take print through printer, the size of image is getting short i.e., it prints like an Icon on Paper. What can I do to get the proper image size on paper also?
The code is as follows, which I have used to render
public class HTMLPrintRenderer implements Printable {
    ReportAbs objReport;
    JEditorPane editorPane;
    String fileName;
    final int STARTING_PAGESET_NUMBER=0;
    int currentPageSetNumber=STARTING_PAGESET_NUMBER;
    /** Creates a new instance of HTMLPrintRenderer */

Hi!
I am stuck with problem of rendering report generated through iText API.
What exactly happens is, I have to put an image (.jpg) on my report, when I am generating HTML file using iText API, the image size is normal i.e., as it is taken.
But when I render it to take print through printer, the size of image is getting short i.e., it prints like an Icon on Paper. What can I do to get the proper image size on paper also?
The code is as follows, which I have used to render

Problem in Running a Webdynpro Application Which uses itext.jar

Hi,
I have created a Webdynpro DC which uses a DC called xxx_lib which contains the external JAR Files. (itext.jar etc)
This JAR file is in my library path as well.
I have added the lib_dc as used DC under the webdynpro DC.
The Compilation and build went fine without any error. But when in run the Application Under ---> Content Administration --> Webdynpro , I am getting the following Error.
The initial exception that caused the request to fail, was:
<b>java.lang.NoClassDefFoundError: com/lowagie/text/Element
Failed to create delegate .....
(Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)</b>
Please let me know if somebody knows the solution.
Thanks and Regards,
Sekar

Hi Sekar,
Please look into the link below.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/7b8180e5-0601-0010-0c94-9bccb92de9c1
Goto section 2.2.3.1 Defining Libraries Page No. 75
It gives you the entire process of creating the library DC and referencing the same in your WebDynpro project.
Hope this helps.

IText - problems importing library

Please, somebody help me!
Why I can't add the iText (PDF) library within an existing WD Project?
It seems to be fine, until the time I run it and get the error: "java.lang.NoClassDefFoundError: com/lowagie/text/Phrase ".
PS.: My WD is not a DC, and I can't change it.
Thanks !!
Fabio

Hi Maksim,
I didn't understand very well what you said with "It MUST contain "library:" prefix".
In the Visual Administrator, my library has the name "itext".
In my project, I've tried everything:
Sharing Reference: itext
Sharing Reference: library:itext
Library Reference: library:text
But when I deploy, it gives the message "The referenced application can't be started".
Only when I put "Library Reference: itext" it deploys ok, but still gives the message "java.lang.NoClassDefFoundError: com/lowagie/text/Phrase", on run-time.
May I have done something wrong??
Can I create everything again?
Thank you!
Regards

Problem with Non-English Fields Output to PDF by JASPER in JDev10.1.3

I am using jsprx files(designed in i-report) to generate pdf reports out of an oracle database.
The non-English fields are shown correctly when I output the report into an HTML or when I view it with JasperView.
If I try making PDF files (JasperExportManager.exportReportToPdfFile) the static fields containing e.g.Arabic/Chineese characters won't be displayed and dynamic fields from the database with non-English contents will be shown as ??? or null.
I received some suggestions about using PARAMETERS to feed the report instead of FIELDS, which I think can not be helpful in this case and in general.
I think this should be a common problem. These are the components I am using:
itext-1.4.7. jar
commons-digester- 1.7.zip
jasperreports- 1.2.8.jar
Any comment or help is appreciated.
Thanks

Memory Allocation Problems

My application seems to not free resources the way I would like it to. The main interface consumes somewhere around 40MB. The application has an option to export data to a few PDFs (via itext and JFreeChart). This is handled through a popup JFrame where the user can select options for export. During the export, memory usage spikes to near 105MB, which though concerning, isn't the main problem. Once the export JFrame has been disposed and control is returned the main window, memory usage stays at ~ 105MB and if you export again, the memory usage doesn't budge, leading me to believe that the Objects used during the export aren't being released. I know that memory management is temperamental in Java, but I can't figure out what's going on here.
Here is an overview of what's happening:
MainViewer -> SaveView -> ExportFileController:
I am currently exporting two PDFs: One containing graphs created by JFreeChart and another containing a table created by itext. I've tested them independently and both seem to stay in memory even after I've called document.close() and SaveView.dispose().
Here is how I'm writing my charts:
public void writeCharts()
          Iterator chartIter = allCharts.iterator();
          try
               System.out.println("Writing Charts: Total Number: " + allCharts.size());
               String outputFile = outputDir.getPath()+"/curvefits.pdf";
               writer = PdfWriter.getInstance(document, new FileOutputStream(outputFile));
               document.open();
               while(chartIter.hasNext())
                    numpages++;
                    JFreeChart currentChart = (JFreeChart)chartIter.next();
                    PdfContentByte cb = writer.getDirectContent();
                    PdfTemplate tp = cb.createTemplate(width, height);
                    Graphics2D g2d = tp.createGraphics(width, height, new DefaultFontMapper());
                    Rectangle2D r2d = new Rectangle2D.Double(0, 0, width, height);
                    System.out.println("Writting Chart: " + currentChart.getTitle().getText());
                    currentChart.draw(g2d, r2d);
                    g2d.dispose();
                    cb.addTemplate(tp, 0, 0);
                    document.newPage();
                    writer.releaseTemplate(tp); //I had heap errors before I added this
          catch(Exception e)
               e.printStackTrace();
          document.close();
          writer.flush();
          writer.close();
          allCharts.clear();
          allCharts.trimToSize();
          System.gc();    //I'm explicitly trying to free up the resources here
          System.runFinalization();
}

Hard to say.
Once it loads classes, it won't give that memory back, but any memory used on the heap which is no longer needed may be reclaimed.
Does it keep climbing on repeated exports, or does it basically peak on one export and remain at that usage level upon repeated exports?It peaks on one export and then remains the same on repeated exports (roughly ~105MB). What scares me is the my test set is relatively small (perhaps as small as 1%) of what this application could be used for. I can do some things to minimize memory usage (like writing one page at a time and then appending so I don't have to keep the whole output stream open) at the expense of speed, but some where there has to be a data structure containing all of the items to be written. If the JVM NEVER gives the memory back then this will pretty much cripple the user's system.

Also an honorable way to make money IMO.I was using iText before 2004 when the first edition of the book came out ( 4 years or so after the library was first introduced) and it was hard work. PDF is a very complex document format and just using the Javadoc does not really get you anywhere. There are many 'gotchas' in iText and most of the iText tutorials cover only the very basics and pretty much none of the 'gochas'. The book starts off with very simple examples that could be constructed from the Javadoc but then it does move on to the more complex issues. Worth every penny.

How to write special characters in PDF using iText

How to write special characters encoded with UTF-8 in PDF using iText.
Regards,
Pandharinath.

I don't know what your problem is but that's almost certainly the wrong question to ask about it. Java (including iText) uses only Unicode characters. (You may consider some of them to be "special" if you like but Unicode doesn't.) And when it does that, they aren't encoded in UTF-8 or any other encoding.
So can you describe your problem? That question doesn't make sense.
