• Microsoft Windows or a compatible OS with Java Runtime Environment for JSP/JSF Application and Desktop Applications.
• Get latest version of Aspose.Words for Java directly from Maven.

Following source code shows how to create a Word RTF file using Java.

Document rtf = new Document();  DocumentBuilder builder = new DocumentBuilder(rtf); builder.write("hello world");  rtf.save("created_file.rtf"); 

A Document Processing Library to perform a wide range of document creation, management and manipulation tasks including RTF generation, editing, conversion, rendering and printing. Java Word API supports all of word-processing formats as well as allows exporting or converting RTF to PDF, HTML, fixed-layout and most commonly used image & multimedia formats.

RTF What is RTF File Format

Introduced and documented by Microsoft, the Rich Text Format (RTF) represents a method of encoding formatted text and graphics for use within applications. The format facilitates cross-platform document exchange with other Microsoft Products, thus serving the purpose of interoperability. This capability makes it a standard of data transfer between word processing software and, hence, contents can be transferred from one operating system to another without losing document formatting. The file format specifications are available by Microsoft for public download and can be referred to from developer’s perspective.

Other Supported Document Generation

You can also create other Microsoft Word files including few listed below.

Writing simple RTF files in Java

I am using Java 6, Windows XP, Eclipce Java EE IDE Juno, Swing. Im looking for the simplest solution without adding any new librarys. To describe my question i will first start with describing my goal.

My idea is to print out in the following format:

Heading

stuffs stuffs stuffs stuffs stuffs stuffs

I would like to get to this goal by using rtf file format. What i have concluded is that i should probably use JEditorPane and some how add line by line formated text into the editor. After im done i would like to write the JEditorPane to file and save it.

So, that said. There are some questionmarks here i do not seem to figure out.

What «standard» class can i use to create RTF formated string lines? Is JEditorPane the best container for a RTF document?

The documentation has everything you need. (http://goo.gl/EJSpx)

• Create javax.swing.text.rtf.rtfeditorkit by calling createEditorKitForContentType
• Add newly created editorkit to JEditorPane by calling registerEditorKitForContentType (notice that support for rtf is limited)

Hope this put you on the right path.

How can I start a RTF editor from scratch(using Java), I suspect that jodconverter can do this too, but if not, you can look at this question: Convert HTML to RTF in java?. This should give you a better idea of how to do your project. There are Java libraries to handle conversion between HTML and RTF, so you can use an HTML editor (provided by JavaFX). And of …

How do I generate RTF from Java?

I work on a web-based tool where we offer customized prints.

Currently we build an XML structure with Java, feed it to the XMLmind XSL-FO Converter along with customized XSL-FO, which then produces an RTF document.

This works fine on simple layouts, but there’s some problem areas where I’d like greater control, or where I can’t do what I want at all. F.ex: tables in header, footers (e.g., page numbers), columns, having a separate column setup or different page number info on the first page, etc.

Do any of you know of better alternatives, either to XMLmind or to the way we get from data to RTF, i.e., Java-> XML, XML+XSL-> RTF? (The only practical limitation for us is the JVM.)

You can take a look at a new library called jRTF. It allows you to create new RTF documents and to fill rtf templates.

Have you had a look at the iText library? It’s touted primarily as a PDF generator, though it can also generate RTF. I haven’t had cause to use it personally, but the general feeling I get is that it’s good, and the interface looks comprehensive and easy to work to in the abstract. Whether it would fit in well with your existing data model is another question.

If you could afford spending some money, you could use Aspose.Words, a professional library for creating Word and RTF documents for Java and .NET.

Java — Read Text from RTF file, Or look at this answer: Java API to convert RTF file to Word document (97-2003 format) There is no free library that supports this. But it may not be that hard to create a basic compare function yourself. You can read in an rtf file and then extract the text like this:

Read Text from RTF file

I tried to read RTF file using Apache POI but I found issues with it. It reports Invalid Header exception. It seems like POI doesn’t support rtf files. Is there any way to read .rtf using any open source java API . (I heard about Aspose API but it’s not free)

You can try the RTFEditorKit. It supports images and text as well.

Or look at this answer: Java API to convert RTF file to Word document (97-2003 format)

There is no free library that supports this. But it may not be that hard to create a basic compare function yourself. You can read in an rtf file and then extract the text like this:

// read rtf from file JEditorPane p = new JEditorPane(); p.setContentType("text/rtf"); EditorKit rtfKit = p.getEditorKitForContentType("text/rtf"); rtfKit.read(new FileReader(fileName), p.getDocument(), 0); rtfKit = null; // convert to text EditorKit txtKit = p.getEditorKitForContentType("text/plain"); Writer writer = new StringWriter(); txtKit.write(writer, p.getDocument(), 0, p.getDocument().getLength()); String documentText = writer.toString(); 

Detect encoding of RTF document in Java, RTF is an 8-bit format. That would limit it to ASCII, but RTF can encode characters beyond ASCII by escape sequences. The character escapes are of two types: code page escapes and Unicode escapes. In a code page escape, two hexadecimal digits following an apostrophe are used for denoting a character …

Formatting rtf file in Java

Ok so I’m trying to create an .rtf file using Java . I didn’t know the syntax so what I did was I created an rtf file using TextEdit on a Mac then opening it with plaintext to see the code. I used this to create my output method which is as followed:

/* Creates RTF */ public String createRTF() < String l1 = "\n\n"; String l3 = " \n\n"; String l4 = "\\margl1440\\margr1440\\vieww10800\\viewh8400\\viewkind0 \n\n"; String l5 = "\\pard\\tx720\\tx1440\\tx2160\\tx2880\\tx3600\\tx4320\\tx5040\\tx5760\\tx6480\\tx7200\\tx7920\\tx8640\\pardirnatural \n\n"; String l6 = "\n\n"; String l7 = "\\f0\\fs24 \\cf0 Original Sequences:\\ \n\n"; String l8 = "\\ \n\n"; String l9 = sequence1 + "\\ \n\n"; String l10 = sequence2 + "\\ \n\n"; String l11 = "\\ \n"; String l12 = "Alignment:\\ \n\n"; String l13 = "\\ \n\n"; String l14 = s1Align + "\\ \n\n"; String l15 = aligned + "\\ \n\n"; String l16 = s2Align + "\\ \n\n"; String l17 = "\\ \n\n"; String l18 = "Score: " + score + ">"; String rtfString = l1 + l2 + l3 + l4 + l5 + l6 + l7 + l8 + l9 + l10 + l11 + l12 + l13 + l14 + l15 + l16 + l17 + l18; return rtfString; > 

I know it’s a little sloppy but I was trying to be as specific as possible and to separate the lines because when I manually made the file in TextEdit the rtf code was:

  <\colortbl;\red255\green255\blue255;>\margl1440\margr1440\vieww10800\viewh8400\viewkind0 \pard\tx560\tx1120\tx1680\tx2240\tx2800\tx3360\tx3920\tx4480\tx5040\tx5600\tx6160\tx6720\pardirnatural \f0\fs24 \cf0 Original Sequences:\ \ ACGTTGTACCA\ AGTTAAACCGTAAA\ \ Alignment:\ \ ACGTTGTACC--A--\ | ||| ||| | \ A-GTTAAACCGTAAA\ \ Score: 3> 

My problem is this is exactly how my rtf code looks when I save a file using my program, but when I open the formatted file using TextEdit it’s one continuos string not separated by lines like I want it. Funny thing is when I add the line breaks myself in TextEdit then save it the rtf code looks exactly the same. I tried adding two /n/n at the end of my strings but that didn’t work. Is there a way to accomplish this output?

See Rich Text Format (RTF) Version 1.5 Specification

So a backslash followed by CR + LF will act as \par — a paragraph.

A carriage return (character value 13) or linefeed (character value 10) will be treated as a \par control if the character is preceded by a backslash. You must include the backslash; otherwise, RTF ignores the control word. (You may also want to insert a carriage-return/linefeed pair without backslashes at least every 255 characters for better text transmission over communication lines.)

Use \r\n instead of \n . That should fix the problem.

Use a string builder object to build your rtfString , its append method to build the string and the system’s line separator for new lines , such as :

I’d hate to answer my own question but I did find the solution. Since what I wanted to display was in a par , I needed to add //line to the end of my Strings to properly put a new line in the middle of a paragraph. Thank you everyone for your help!
