Add text in MS Word doc using apache POI

Question

I have been trying to edit different types of documents using Apache POI. The script should handle both extensions .doc and .docx. I could successfully edit the .docx file using XWPF api and the required text was added at the end of the docx file.

For editing .doc files(which include header, footer and a few paragraphs), following script is used, which use HWPFDocument.

 FileInputStream fis = new FileInputStream(args[0]);

 POIFSFileSystem fs = new POIFSFileSystem(fis);
 HWPFDocument doc = new HWPFDocument(fs);

 Range range = doc.getRange();
 CharacterRun run = range.insertAfter("FROM SEHWAGGG A FOUUURRRRRR");
 run.setBold(true);
 run.setItalic(true);

The script works fine with normal documents which does not have header and footer. But seems that the issue appears with complex documents. It insert text, but in between the paragraphs (and at the beginning using insertBefore()). There are no text replacements required, just have to put the text at the end of the document. I searched similar scripts but most of them handle text replacement.

How can I add the text at the end, after all paragraphs?

Answer 1

I'm afraid you are out of luck with HWPF with the current state of the project.

I created a custom HWPF library for one of our clients, but the changes are not public. The changes were huge, so you can't spend - say - a week and assume that things will be fixed. You might get away with the current public HWPF when only some text needs to be replaced without changing the string length ("abc" -> "123" or "a " -> "1234").

I've tested It with the following document:

At first (with your original code) it completely destroyed the document:

By changing the following line, the insert works fine for me:

// Old
Range range = doc.getEndnoteRange();
// New
Range range = doc.getEndnoteRange();
