Is there a way to open an existing PDF file with some template and continue drawing on it?
I'm using https://developer.android.com/reference/android/print/pdf/PrintedPdfDocument but it only works with new files.
There is nothing in the Android SDK that allows you to modify existing PDF files for any purpose, let alone printing. You will need to look at third-party libraries for that (e.g., iText).

I'm creating a JAVA application
and I want to create and display and print a PDF file.
Like this example:

So can you give the right way to do it ?
I mean is this a pdf file displayed into a JPanel or something else ?
and thnx alot.
For working with PDF files I would recommend using a library such as Apache PDFBox which has the ability to write, read, and print PDF files using org.apache.pdfbox.PrintPDF
The API can be found Here
As for displaying it in the JFrame, you can simply read the text and print it out in a Swing Text Area
For generation of pdf files you can use Jasper Reports library. It is popular API for creation pdf files from template in which specific data is inserted. Template files have ".jrxml" extension and can be created and edited by Jaspersoft Studio. These files look like forms with variable fields, this is very useful for generating different kinds of reports.
The API for Jasper Reports Library can be found here.
Actually I am attempting to extract the data from a PDF file but I didn't find any example in the internet and I am asking if there is any possibility that I can use the JPedal library to open to read the data from a PDF file.
You can use PDFBox from Apache.
I am not familiar with JPedal, but I write lots of code that generates and processes pdf files. I use IText and highly recommend it. If you have a specific question on how to process a pdf file, let me know.
I have some PDF template (with header and footer). I want to generate documents that are based on that template.
Is there any way to do that with iText? Thank you
P.S. Right now I am generate a document on-fly i.e. every time I generate header, footer and the context itself.
UPDATE: I have found incredible library called PD4ML. It's not free, but not such expensive, BUT it has really cool features such as HTML2PDF conversion on fly, supports a lot of HTML-CSS tags and has even its own jsp tags library! So I really suggest it when you need something instead of heavy and memory-eating JasperReports.
You can use JasperReports library and the iReport visual designer.
JasperReports use iText to produce PDFs from "jasper" templates, that are XML files (following the jrxml DTD) compiled in java classes, but allows you to use the template for generating MS Office files (with POI), html, etc.
Im not sure with iText, but you can use BIRT for this purpose. http://www.eclipse.org/birt/ Its too much using it just for PDF creation, you can do a lot (more than you can imagine) with it.
If you can choose your template format. I would go with JODReport and JODConverter.
JODReport use an ODT template and fill the mapping in the template with your java code.
JODConverter use LibreOffice to convert such template in PDF or whatever fortmat LibreOffice can handle to export.
You have to be able to use LibreOffice as a service installed remotely on a machine.
I used it back in 2012 but not sure if the project is still active
Is it possible to open or create a PDF file in a Java desktop application just like we can create text file?
From my search I got that it is possible only with web java. Is that true?
To open an existing PDF file in the desktop default reader you can use the following code:
File pdf = new File("/path/to/your.pdf");
Desktop.getDesktop().open(pdf);
(needs Java 6)
You can use iText to do this. Here is a nice tutorial.
There is an OS PDF plugin for Netbeans at http://www.jpedal.org/support_siNetBeans.php
You can not create PDF just like a normal Text file, you will need PDF Library to create one. Opening an existing PDF is possible like *a_horse_with_no_name* mentioned in his answer.
You can find some PDF Libraries here.
Is there a way to convert a xls file into a pdf?
I want to make a dynamical report directly to pdf file, but didn't find a way to make dynamic columns on iReport, so I've made a method on Java that exports to xls dynamically.
So I was wondering if is there a way to convert this file to pdf, but it need to be on a method from my code. Or if you have a better idea, it can be used too.
Maybe there's a way to make this pdf file from my code as I did with xls. Please help me out.
Thanks.
Try using iText http://itextpdf.com/ - I've used it to create PDFs with columnar structure.
In addition to using iText directly, there are a couple report engines that sit on top of it:
Eclipse BIRT (using 2.1.7, the last MPL/LGPL version)
Jasper Reports (which uses a Very Old version, 1.3.1 IIRC)
This is a commercial solution:

If you want open source try jakarta POI.
Try using the Muhimbi PDF Converter Services. It comes with a Java compatible Web Services based interface and sample code. It does other things as well.
I worked on this application, so the usual disclaimer applies.
