Corrupted file when creating Word document

Question

I'm quite new to docx4j. After installing everything, I tried creating an empty .docx file, and then write text in it. Here's the code :

WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage();
wordMLPackage.getMainDocumentPart().addParagraphOfText("Hello Word!");
wordMLPackage.save(new java.io.File("HelloWord1.docx"));

The file is succesfully created, but when I try to open it with Word 2010, I get an error message saying the file is corrupted. However, when I open it with WordPad, everything is fine, and the text is there. What could I do to solve this problem and open my created documents with Word 2010 ?

EDIT : I converted the corrupted file to zip, here's document.xml :

<?xml version="1.0" encoding="UTF-8" standalone="true"?>

EDIT 2 : So after hours scratching my head to solve that, I completly uninstalled and deleted all references to docx4j, the re-added the JAR files. For some reason, no more problems after that.

Answer 1

I ran this exact code, using the current stable release of docx4j (v3.1) with no issues. A document was created and opened just fine in MS Word 2010. Here's the complete content of my test class, which creates a Word file in a 'test' directory in my C drive (adjust for your machine / OS, obviously):

public class PlayDocx4J {

    public static void main(String[] args) {

        try {
            WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage();
            wordMLPackage.getMainDocumentPart().addParagraphOfText("Hello Word!");
            wordMLPackage.save(new java.io.File("c:/test/helloword.docx"));
        } catch (Docx4JException e) {
            System.err.println("ERROR " + e.getMessage());
            e.printStackTrace();
        }
    }
}

Update re XML having examined the document.xml file content you provided, the issue is with the XML declaration in there. As it stands, it throws a corrupt document error in Word. Word also tells you what the problem is (error in line #1, column 54). If you remove the standalone="true" attribute, and then paste the edited document.xml back into the zip file, it will open without any issue.

This raises the question why your generated file contains this declaration (it shouldn't, and I believe the proper value is standalone="yes" in any case). The answer must lie with the XML transformer being used in your Java implementation.

(You can read more about this declaration here: http://www.xmlplease.com/xml/xmlquotations/standalone).
