How can I open a Microsoft Word docx file in Java? furthermore, how can I open it if it is password protected?
For instance,
File f = new File("hello.docx");
Please try to avoid responding with things such as "you shouldn't do this." I have a good reason for this, so please stick to the question when you answer. thanks a lot!
There is Apache POI project for working with MS Office files. DOCX file is just a zip file with series of XML files inside, so you can unzip the file and work with XML. The XML spec (Open XML) is known.
I haven't personally used it, but it looks like Apache POI will work for you: http://poi.apache.org/
You can use docx4j too. http://www.docx4java.org/trac/docx4j
I have used both docx4j and Apache's POI libraries, if you are working with .docx I would recommend .docx4j. Automated alot of the process of creating a .docx.
There is a great exmaple here : http://java.dzone.com/articles/create-complex-word-docx
on how to create a .docx using the docx4j package.
If the docx is password protected, it won't be a zip file. It will be a compound file. See Overview of Protected Office Open XML Documents
To read a compound file in Java, use POIFS. POIFS is part of POI (docx4j uses it as well, so if you download the docx4j distribution, you'll be able to use the POIFS API)
Once you have decrypted the encrypted package, you can read it using docx4j or POI.
Edit: OK, now docx4j can handle password-protected docx automatically.
Have you tried to open it using the Open Office api? It can work with a lot of documents types.
I used it with MS Excel files .xls ( old version ) format.
Hope this can help you.

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 want some API's and some Document So that i can convert any file into PDF..
The file may be Doc , exl, ppt ..etc .
My requirement is, i have a file EX:- Doc file and i just wants to convert it into PDF.. using java .
Any suggestion will be helpful...
I would recommend you taking a look at Flying Saucer (former xhtmlrenderer) which makes creating PDF files extremely easy from XML and HTML files (internally it uses iText).
HTML/XML can be used as a intermediate format making this a quite flexible solution.
Use
http://pdfbox.apache.org/
and
http://poi.apache.org/
If you want to generate a PDF from an XML document, you can try Apache FOP, which follows the XSL-FO standard.
http://xmlgraphics.apache.org/fop/
So a smart process could be: extract data from your various document formats using POI, odftoolkit (for OenDocument) or other tools, inject them into an XML container, and then translate them into PDF using FOP.
Apache's poi API is best for convert any file to pdf
You can use Itext . It is well documented and comes with ton of examples.
I want to convert .doc/.xls file into PDF through my java application. Now, I know there have been some discussions on this topic. I also know that JODConverter is one option, but the problem with this is dependency on OpenOffice. Whoever wants to use my app will first need to install OpenOffice on his/her host. I want to avoid this. Do we have any new solution through which I can do this conversion in my app without having dependencies on any other applications.
You could use POI for reading XLS and DOC, and use iText for generating the PDF.
POI project:
http://jakarta.apache.org/poi/
iText project:
http://www.lowagie.com/iText
We are converting a C++ project to Java where we generate reports in ".doc" extension. The problem is we don't use any third party library to generate MS Word document, rather a file with .doc extension. Everything works fine except that we can't seem to find a way to add a Header at the beginning of every page. Using line numbers is not an option. Any other way it can be done?
Thank you.
The Apache POI library might be of some help.
It has facilities to read and modify Microsoft proprietary file formats like MS-Word .doc and MS-Excel .xls
how to Parse a PDF file and write the content in word file using Java?
For parsing a PDF file in Java, you can use Apache PDFBox: http://incubator.apache.org/pdfbox/
For reading/writing Word (or other Office) file formats in Java, try POI: http://poi.apache.org/
Both are free.
Try the iText java library:
iText is an ideal library for developers looking to enhance web- and other applications with dynamic PDF document generation and/or manipulation.
It can be used for your parsing step.
As for generating word documents - the OpenOffice Java API might be able to generate Word compatible docs (no personal experience with this API).
You might want to try any of these:
http://incubator.apache.org/pdfbox/
https://pdf-renderer.dev.java.net/
Once you are reading the contents of the PDF file, you can as well store them in a ODT file or a text file. For ODT file, try http://odftoolkit.openoffice.org.
Best!
You could use iText if the source PDF is mostly text. Images and such are quite hard to handle while parsing. If it's text only, it's as easy as 10 lines of code. See the iText manual for examples.
For writing word files there's only Apache POI. It can be a little tricky to figure out, but for such a simple task it shouldn't be any problem.
