how to create an odt file programmatically with java?
Solution 1
Take a look at ODFDOM - the OpenDocument API
ODFDOM is a free OpenDocument Format (ODF) library. Its purpose is to provide an easy common way to create, access and manipulate ODF files, without requiring detailed knowledge of the ODF specification. It is designed to provide the ODF developer community with an easy lightwork programming API portable to any object-oriented language.
The current reference implementation is written in Java.
// Create a text document from a standard template (empty documents within the JAR)
OdfTextDocument odt = OdfTextDocument.newTextDocument();
// Append text to the end of the document.
odt.addText("This is my very first ODF test");
// Save document
odt.save("MyFilename.odt");
later
As of this writing (2016-02), we are told that these classes are deprecated... big time, and the OdfTextDocument
API documentation tells you:
As of release 0.8.8, replaced by org.odftoolkit.simple.TextDocument in Simple API.
This means you still include the same active .jar file in your project, simple-odf-0.8.1-incubating-jar-with-dependencies.jar
, but you want to be unpacking the following .jar to get the documentation: simple-odf-0.8.1-incubating-javadoc.jar
, rather than odfdom-java-0.8.10-incubating-javadoc.jar
.
Incidentally, the documentation link downloads a bunch of jar files inside a .zip which says "0.6.1"... but most of the stuff inside appears to be more like 0.8.1. I have no idea why they say "as of 0.8.8" in the documentation for the "deprecated" classes: just about everything is already marked deprecated.
The equivalent simple code to the above is then:
odt_doc = org.odftoolkit.simple.TextDocument.newTextDocument()
para = odt_doc.getParagraphByIndex( 0, False )
para.appendTextContent( 'stuff and nonsense' )
odt_doc.save( 'mySpankingNewFile.odt' )
PS am using Jython, but the Java should be obvious.
Solution 2
I have not tried it, but using JOpenDocument may be an option. (It seems to be a pure Java library to generate OpenDocument files.)
Solution 3
A complement of previously given solutions would be JODReports, which allows creating office documents and reports in ODT format (from templates, composed using the LibreOffice/OpenOffice.org Writer word processor).
DocumentTemplateFactory templateFactory = new DocumentTemplateFactory();
DocumentTemplate template = templateFactory .getTemplate(new File("template.odt"));
Map data = new HashMap();
data.put("title", "Title of my doc");
data.put("picture", new RenderedImageSource(ImageIO.read(new File("/tmp/lena.png"))));
data.put("answer", "42");
//...
template.createDocument(data, new FileOutputStream("output.odt"));
Optionally the documents can then be converted to PDF, Word, RTF, etc. with JODConverter.
Edit/update
Here you can find a sample project using JODReports (with non-trivial formatting cases).
Solution 4
I have written a jruby DSL for programmatically manipulating ODF documents.
https://github.com/noah/ocelot
It's not strictly java, but it aims to be much simpler to use than the ODFDOM.
Creating a hello world document is as easy as:
% cat examples/hello.rb
include OCELOT
Text::create "hello" do
paragraph "Hello, world!"
end
There are a few more examples (including a spreadsheet example or two) here.
Solution 5
I have been searching for an answer about this question for myself. I am working on a project for generating documents with different formats and I was in a bad need for library to generate ODT files. I finally can say the that ODFToolkit with the latest version of the simple-odf library is the answer for generating text documents. You can find the the official page here : Apache ODF Toolkit(Incubating) - Simple API Here is a page to download version 0.8.1 (the latest version of Simple API) as I didn't find the latest version at the official page, only version 0.6.1
And here you can find Apache ODF Toolkit (incubating) cookbook

How can I create an odt (LibreOffice/OpenOffice Writer) file with Java programmatically? A "hello world" example will be sufficient. I looked at the OpenOffice website but the documentation wasn't clear.

Tango over 11 yearsThe problem with JOpenDocument is that it still supports primarily spreadsheets and doesn't even have full support for text.

Hendy Irawan over 10 yearsJOpenDocument's latest release is 1.3 from Jul 2013 so it seems to be well maintained. ODFDOM seems no longer maintained, latest "release" on Jan 2012 (it's not even visible from the website) is 0.8.8-incubating.
