How to read doc and docx in java

Question

First you should know I have looked into many questions and none of them helped me. I want to be able to read doc and docx documents (when I say read I mean the simplest thing, reading TEXT ONLY). I saw some posts about poi and scratchpad but I couldn't make it work properly, and most of the times eclipse couldn't even build my project...

Can someone give me a code sample for doc and docx and give me the names (or links) of all the jars I need to use?

Thanks!

Basically this is the code:

try {
    if (getFileExtention(path).equals("docx")) {
        FileInputStream fis = new FileInputStream(path);
        XWPFWordExtractor oleTextExtractor =
            new XWPFWordExtractor(new XWPFDocument(fis));
        return oleTextExtractor.getText();
    } else if (getFileExtention(path).equals("doc")) {
        FileInputStream fis = new FileInputStream(path);
        WordExtractor we = new WordExtractor(fis);
        return we.getText();
    }
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}


return "";

I have the following jars:

dom4j-1.6.1.jar

poi-3.8-20120326.jar

poi-ooxml-3.8-20120326.jar

poi-scratchpad-3.8-20120326.jar

xmlbeans-xmlpublic-2.4.0.jar

I have the following problems:

This one occurs many times during build

Answer 1

• For reading DOCX documents we can use XWPFWordExtractor with XWPFDocument.
• For reading DOC documents we can use WordExtractor with HWPFDocument.

You got the code for DOCX documents right:

XWPFWordExtractor oleTextExtractor = new XWPFWordExtractor(new XWPFDocument(fis));

But HWPFDocument is missing from your code for DOC documents. Just change this line:

WordExtractor we = new WordExtractor(fis);

into this:

WordExtractor we = new WordExtractor(new HWPFDocument(fis));

As regards the jar files, only poi-ooxml-schemas-3.8-20120326.jar seems to be missing from your Build Path.

Answer 2

Tika supports Microsoft Office format as well as many others formats, it provides you with a common interface for all the formats as well as hiding the complexity of maintaining and learning how to use lots of different libraries. It is as easy as calling this function. You could also use the Office Parser and OOXMLParser directly.

Answer 3

You have also very powerful application like LibreOffice SDK (or OpenOffice 3) where you can read and manage documents (like docx) and save them in .txt format.
