I would like to open a pdf file in a new Jframe.
the pdf file exist. I just need to open it and show it in a new Jframe.
I user itext to create the pdf file. do I need the same tool to open it.
please show me how.
thanks in advance.
It is not that easy and straightforward to open PDF inside Swing's JFrame. You can consider purchasing commercial tools such as pdfviewer or use embedded browser like JDIC and display your PDF using embedded PDF Viewer (i.e. Adobe Reader) inside an embedded browser but that is tricky as well.
I would rather seriously consider opening your PDF in OS default PDF viewer using java.awt.Desktop.open() method which is designed to be cross-platform. Note however, that Desktop class is available in Java 1.6 and later.

Currently I'm developing an application that allows users to create a template and generate it into a DOCX file. The application needs to be able to display to users the changes in the template as the user is creating it.
The approach I tried was using DOCX4J library (allows manipulation of DOCX file) and ICEPDF which is primarily used to display the DOCX into the swing component by converting it first into a PDF file. Now the problem in this approach is that it loads pretty slow and some of the changes that occurs in the DOCX file does not reflect on the PDF conversion (example: dashed underline, font changes). When I tried to open the DOCX file ouput in MS WORD, the file is viewed correctly so I know changes do occur, but it seems that ICEPDF just can't show it properly.
So I was wondering if anyone knows a java library that allows DOCX files to be viewed directly from a Swing Component instead of converting it first into a PDF file.
You can try docx4all or DocxEditorKit. Both of these are built around docx4j.
I'm implementing a patch in Jabref (reference management software): I want to embed a pdf reader in it. This feature has been done in Mendeley and Papers, and it's very useful if you can read/markup pdfs right inside of Jabref.
Instead of writing a pdf viewer, I want to embed outside program inside Jabref, such as Adobe Reader, or PDF Document Viewer in Ubuntu. Is there anyway to do that?
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.
I developed a report (without and independent of any db datasource) only with iText. I know that with JasperReports this is easy. But in my case I just storage the report in pdf file or I used acrobat for java beans to show the report to user. Now I need to change my implementation code to show this report in web browser instead to save in the file.
How I can do this?
You need 2 thinks, first the browser plugin installed on the browser and second to set the content disposition header as inline in the respose, otherwise the browser will try to download it.
response.setHeader("Content-Disposition","inline; filename=\"file.pdf\"");
I assume that you've already set the Content Type to application/pdf and know how to convert an iText document to a bytearray and transmit it to the user.
A word of caution: if people outside your organization will use this app, the might not have the pdf plugin installed, in which case, the browse will download the pdf instead of displaying the pdf.
if the browser has the appropriate add-on installed, you can just drag and drop a pdf-file into the browser and it will show it.
Or if you have a site on which you want to present the pdf, you just put a link to it:
link to your pdf
Or did you mean you want to generate html-output for your report instead of pdf?
We have Flex on the front end and Java on the back end. When a user will request for a PDF file, request will go to the Java backend, where a PDF file will be generated using Jasper Reports. What we dont know is how to display this PDF file in browser; since we dont want to use JSP/Servlets etc - It has to be flex only. Any suggestions?
Flash Player cannot natively render PDF files. This is possible using Adobe AIR but not in a Flex application. Your best bet is to call navigateToURL() and open a Servlet in a new browser tab/window. The Servlet can simply write contents of the PDF file to the OutputStream and set the appropriate HTTP headers.
i think this question is old, but it may help others, there's a new library developed by Jasper Forge them selves, which deals with JasperReports directly, i mean it's not a PDF viewer, but a JasperReport exporting tool, you can download it from here
i tried it through using JasperServer, when viewing reports you can choose from different options to export it, one of them is flash, and it's working nice
Well for starters, PDFs don't always display in the browser. It depends on the user's settings. You essentially header them the pdf file and either they download it or a program like Acrobat Reader opens in the browser to display it.
Not sure how this is done in flex, I would imagine if you're using Java one simple servlet could do it.
