Answer 1

This is a relatively common problem with many applications, not just JDOM.

When you create a FileOutputStream, and write to it, you HAVE TO FLUSH IT AND CLOSE IT before exiting your program.

Change:

xmlOutput.output(doc, new FileOutputStream(new File("./src/Lexicon.xml")));

to be (using try-with-resources):

try (OutputStream fileout = new FileOutputStream(new File("./src/Lexicon.xml"))) {
    xmlOutput.output(doc, fileout);
}

or:

OutputStream fileout = new FileOutputStream(new File("./src/Lexicon.xml"));
xmlOutput.output(doc, fileout);
fileout.flush();
fileout.close();
