iText Merge & old documents problem

2008-09-26T08:29:18Z

I'm using iText and Coldfusion and I seem to have an intermittent problem after my users merge documents via a web checklist form. The site has a dropdown box where a user can choose a watermark to add to the top of the page, and then a series of checkboxes of the pdfs they want to merge together, with the watermark on each page.

For the most part, this works 90% of the time, but every now and again, I'll get a call that after they hit submit to merge the docs and it shows their requested merge, it shows a previous document they merged hours ago, and no matter how many times they select different docs to merge, or different watermark, it still shows the old docs.

I've found that if I goto the folder where the merged docs gets saved, and then delete them (if it doesn't give me a: Cannot delete, file is being used by another person or program - error), then it allows a successful merge.

Is this a server issue, or perhaps I need to add some code to flush out/delete the files somehow. Thoughts?

PDF silent print

2008-08-22T14:06:21Z

I need to silently print a PDF file to the user selected printer (selected in an earlier step), i.e., print the PDF file when the document loads without requiring the user to hit print. I also need a way to present the user with the list of printers attached to his computer to allow him to make a selection. Below is a sequence of things that need to happen:

1) Browser provides a list of available printers to the user
2) User selects a printer
3) Browser sends a request to the server(Websphere), including the printer information
4) Server generates the PDF document and returns the response
5) PDF document once loaded completely should print silently (Adobe PDF reader plug-in will issue the print), without requiring the user to do anything

This all needs to be done in an intranet web application using IE, Adobe PDF reader plug-in (free version), JSP/Servlet, IText and Websphere.

Google provided with some information on scripting the PDF file to silent print, but as you can see in the attached screen shot this is not working as expected. Also, I didn’t find a way to query, display and store client’s printer(s) information.

FYI, below is the Java/IText code that adds scripting to the PDF document:
PdfWriter writer = PdfWriter.getInstance(document, baos);
StringBuffer javascript = new StringBuffer();
javascript.append("var params= this.getPrintParams();");
javascript.append("params.interactive=params.constants.interactionLevel.silent;");
javascript.append("params.pageHandling =params.constants.handling.shrink;");
\\javascript.append("params.printername = \"\\\\\\\\PRNSRV17\\\\LN1011070;\"");
javascript.append("this.print(params);");
writer.addJavaScript(javascript.toString(),false);

If anyone of you have run into a similar problem before or have a solution/ideas for this problem, please let me know.

Thanks for your time!

Special characters

2008-07-18T00:57:30Z

Dear ladies and gentleman,
we have a little problem with special characters like ß,ö,ä.
Our situation is the following:
We have an online form server, from which our pdf files can be downloaded and opened in an browser. Before downloading we fill the form with some values. All this values are shown in the browser except special symbols like ß,ö,ä.
We have done the same with iText 1.4.5. But with iText 1.4.5 also the special symbols are shown.

The question now is: how can we fill our forms with a new iText so that also special symbols are shown in the browser.
Thanks for your help

lot of space in generated PDF

2008-07-03T05:36:52Z

I am generating PDF from html content. for this i have used HTMLWorker. The code is like this

ArrayList list=HTMLWorker.parseToList(new StringReader(sb.toString()),style);
for(int i=0;i<list.size();i++)
{
document.add((Element)list.get(i));
}

where document is object of Document.

My generated PDF is fine, the only problem is if the content is too much, lot of space comes in PDF. It is like 1 page with content, next page with only header and then all space, then again the next with content, in random order.

please help.

clickable image not working with itext version 2.0.6

2008-06-10T01:54:02Z

Hi,

Let me describe the problem I am facing: The pdf to be generated by itext has an image which should be clickable and opens the url in new browser window (or already opened browser window, but not in the same pdf).
I was using itext 1.4.2 some months back and I was getting the expected result as mentioned above.
Code excerpt I used:

Image image = Image.getInstance(imageUrl);
Chunk imageChunk = new Chunk(image, 0, 0);
String imageHyperlink = someURL;

Anchor anchor = new Anchor(imageChunk);
anchor.setReference(imageHyperlink);
PdfPCell myCell = new PdfPCell (new IciParagraph(anchor));

Now due to some new requirements I switched to itext 2.0.6 but the above thing doesn't work. Image is not clickable anymore. To fix this I removed the last line and added this code :

Paragraph myPara = new Paragraph ();
myPara .add(anchor);
PdfPCell myCell = new PdfPCell (myPara);

With this change the image becomes clickable but it opens the url in the same pdf window. Please let me know what's going wrong with this new itext version and what is the workaround for the problem?

Thanks in advance

itext and Java Servlets: problem

2008-03-25T06:12:28Z

Hello,

I have created a pdf file with itext using a Java Servlet. When I call the servlet, I open the file in the Web Browser. For that, I use the next code in the Servlet class:

res.setHeader("expires", "0");
res.setContentType("application/pdf");
res.setHeader("Pragma", "public");
res.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
res.setHeader("max-age","0");
res.setHeader("Content-Disposition","inline; filename="+ strArchivo + ".pdf");

However, when I save a copy of the pdf file, the name shown is not the specified by strArchivo, but it is "http___....pdf".

If I use res.setHeader("Content-Disposition","attachment; filename="+ strArchivo + ".pdf"); it works, but it doesn't work with "inline".

How can I resolve the problem? Can I set the file name with itext?

Thanks.

how to create PdfPTable which is having support of "Splitting tables over several pages" and "rowSpan" together

2008-03-20T01:12:55Z

I am currently using itext 2.0.7 where pdfpTable is not having support for rowSpan, as PdfpTable Data Structure got modified.
Previously I was using itext1.4.2 where rowspan support was there and things were working fine, but support for "Splitting tables over several pages" wasn't there. for this reason I upgraded to the latest version.
I need support of "Splitting tables over several pages" and "rowSpan" both together.
I tried the work around mentioned into itext document for rowspan but this not solving my purpose.

I get rowspan size and all other data to create Table structure dynamically.

my tables looks something like following, where data in column can go beyond one page.
(can have more columns, rows, different colspan, rowspan )

Re: Post same form multiple times with different data

2008-03-11T07:00:30Z

well, I've gotte a version of what I want to work starting from an example at http://www.lowagie.com/itextwiki/doku.php/forms:learningagreement - it requires version 2 of iText, and I'm still interested in learning another method that I've seen mentioned, but this will probably serve for the application I'm writing now.

// outputSpec is a string specifying the filepath for the output file
// (i.e., the PDF that is produced by this code). inputSpec is
// the path to the PDF form with fields that I'm going to fill.
Document document = new Document(); // this is an iText class
PdfSmartCopy outputCopy // PdfSmartCopy is a v2 iText class
= new PdfSmartCopy(document,
new FileOutputStream(outputSpec));
document.open();

for (int i=0; i<list.size(); i++) // my list has one element per set of data,
// and therefore one elemenet per PDF page.
{
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

// starting here, example logic in "fillAgreementForm(x,y)"
PdfReader reader = new PdfReader(inputSpec);
PdfStamper stamper = new PdfStamper(reader, outputStream);
AcroFields pdfFieldsForm = stamper.getAcroFields();

// fieldValueMap: each key is the name of a field on the form,
// each value is a key allowing retrieval of the data to be put
// on that field.
Iterator keys = fieldValueMap.keySet().iterator();
while (keys.hasNext())
{
String docKey = (String)keys.next();
String valueKey = (String)fieldValueMap.get(docKey);
String value = getValueForField(valueKey); // skipping all error handling
pdfFieldsForm.setField(docKey, value);
}
stamper.setFormFlattening(true);
stamper.close();

PdfReader resultReader = new PdfReader(outputStream.toByteArray());
outputCopy.addPage(outputCopy.getImportedPage(resultReader,1));
// both the example I copied and my own have one page in the document
// that is filled with data; I don't know what to do if it has more than that.
}

document.close();

So, this is working and appears to produce a 7-page PDF that is one-third the size
of one produced by concatenating separate PDF files.

I'm still interested in the method I've seen mentioned of reading the file once to
get the positions of the fields, storing those, then flattening the form and writing
the data to the positions instead of using pdfFieldsForm.setField(). I don't know
how to do that one yet -- I do not yet understand the "outputCopy.addPage()"
in this example, and I don't know how to do the equivalent in that version. If
someone can point me/us to that, I'd appreciate it.

Re: Post same form multiple times with different data

2008-03-10T15:44:26Z

I sought out a forum like this so I could ask the same question.

I've been through chapter 14 of the book twice, but I'm still missing something. It gives XML examples, and uses a class provided with the library to parse an XML file multiple times and insert different data into it. I've got an AcroForm with fields, and I have code that replaces the fields with my own data, and that works for one document.

I read in the book that PDF supports having a form placed in the document one time, and data provided multiple times for that form, without repeating the form information for each new set of data. That's what I want to find out more about. I don't know what call to make to say "here is a new set of data for a form you already have". Can someone indicate which call to look into?

Thanks. I think this would answer the original poster's question, as well as my own.

In case it's interesting to someone, below is a skeleton of the code I use to do what I do so far:

PdfReader reader = new PdfReader(pdfInputFilename);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(outputFilename);

AcroFields fields = stamper.getAcroFields();

fields.setField(fieldName, fieldValue);
// repeat above line for any number of fields for which you have name and value

stamper.setFormFlattening(true);
stamper.close();

Post same form multiple times with different data

2008-03-10T07:36:43Z

Could somebody show some working example of iText-Java code or point to a url which demonstrates the following:
1. Post the same form multiple times with different data.
2. Is it a good idea to keep the form in memory, instead of reading the form every time for every posting?

The data changes for every submission, but the form is the same for every posting.
Thanks for your time in advance.
