Write to word tablecell with Java, Apache POI?

[Robin Jönsson]

I have word document with a table in. I want to insert text in those cells with Java and I have added Apache POI to my project...

However, I have only succeed to read from the document. My application gets all cells in the table... But I dont know how to insert new text in each cell? Any ideas?

Thanks in advanced

      String SOURCE_FILE = "template.doc";

        DocumentProcessor instance = new DocumentProcessor();
        HWPFDocument doc = null;
        try {
            doc = instance.openDocument(SOURCE_FILE);

            Range range = doc.getRange();
            TableIterator itr = new TableIterator(range);
            while(itr.hasNext()) {
                Table table = itr.next();
                for (int rowIndex = 0; rowIndex < table.numRows(); rowIndex++) {
                    TableRow row = table.getRow(rowIndex);
                    for (int colIndex = 0; colIndex < row.numCells(); colIndex++) {
                        TableCell cell = row.getCell(colIndex);
                        cell.getParagraph(0).text().replace("", "Hello");
                        System.out.println(cell.getParagraph(0).text());
                    }
                }
            }

        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            saveDocument(doc, SOURCE_FILE);

        }
    }


    private HWPFDocument openDocument(String file) throws Exception {
        URL res = getClass().getClassLoader().getResource(file);
        HWPFDocument document = null;
        if (res != null) {
            document = new HWPFDocument(new POIFSFileSystem(
                    new File(res.getPath())));
        }
        return document;
    }

    private static void saveDocument(HWPFDocument doc, String file) {
        try (FileOutputStream out = new FileOutputStream(file)) {
            doc.write(out);
            doc.close();
            System.out.println("File saved");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

The POI HWPF and XWPF APIs are quite limited in what they can do, particularly with respect to altering documents (as opposed to reading them). Read http://poi.apache.org/document/quick-guide.html to get a feeling for how limited. If you look through the code examples at http://svn.apache.org/viewvc/poi/trunk/src/scratchpad/testcases/org/apache/poi/hwpf/ you may find some useful stuff, but frankly, I doubt that you will be successful. I looked into this some years ago, and re-reading it now, the situation doesn't seem to have improved much.

The issue is they haven't had anyone to actually take ownership of the project for years.
It's essentially stagnated and, as the link Tim posted says, it's never come out of the scratchpad.

I know this is a long time since posted but

row.createCell() creates a new cell in a row.
