org.apache.xmlbeans.impl.values.XmlValueDisconnectedException when write workbook twice [duplicate]

Answer 1

Writing twice to the same XSSFWorkbook can produce that error - it's a known bug.

Answer 2

Agree with Akokskis, writing twice causing problem, but you can try reloading again the workbook after writing, then it will perfectly work. For example

    FileOutputStream fileOut = new FileOutputStream("Workbook.xlsx");
    wb.write(fileOut);
    fileOut.close();
    wb = new XSSFWorkbook(new FileInputStream("Workbook.xlsx"));
