I am facing a little challenge with my coding.

File file = new File("template.ods");
Sheet sheet;
try {
    // load file
    sheet = SpreadSheet.createFromFile(file).getSheet("Certificate");
    System.out.println(file);
    System.out.println(sheet.getCellAt("A1").isEmpty());
    sheet.setValueAt("A1", 1, 1);;
    System.out.println(sheet.getCellAt(1, 1).getTextValue());
    sheet.getCellAt(2, 2).setValue("B2");
    sheet.getCellAt(3, 3).setValue("C3");
    sheet.getCellAt(4, 4).setValue("D4");
    // Save to file and open it.
    File outputFile = new File("fillingTest.ods");
    OOUtils.open(sheet.getSpreadSheet().saveAs(outputFile));

} catch (Exception e) {
    e.printStackTrace();
}

I am getting to know the jOpenDocument-Library. I want to fill an existing OpenOffice-Spreadsheet-Template (template.ods) with some sample values. When running the above code, the console shows this:

template.ods
true

java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
    at java.util.ArrayList.rangeCheck(Unknown Source)
    at java.util.ArrayList.get(Unknown Source)
    at org.jopendocument.dom.spreadsheet.Table.getRow(Unknown Source)
    at org.jopendocument.dom.spreadsheet.Table.getImmutableCellAt(Unknown Source)
    at org.jopendocument.dom.spreadsheet.Table.getValueAt(Unknown Source)
    at org.jopendocument.dom.spreadsheet.Table.setValueAt(Unknown Source)
    at jOpenDocument.createDocument.main(createDocument.java:48)

"template.ods" and "true" shows that the application retrieved the file from directory and "true" that it could read the cell, which is empty.

But I don't know which Array throws the Exception and why it says "Unknown Source".

Array of rows throws the exception. Try adding more rows with sheet.setRowCount() before setting cell contents.

You could use ensureRowCount, which is more appropriate in my opinion:

sheet.ensureRowCount(row);
