Exception when writing to the xlsx document several times using apache poi 3.7

Question

I am getting the following exception while trying to write an .xlsx file using Apache POI: org.apache.xmlbeans.impl.values.XmlValueDisconnectedException

Answer 1

I had the same problem too. Later, I tried another method and it solved.
In this case, we can move the code:

FileOutputStream fileOut = new FileOutputStream("workbook.xlsx");
workbook.write(fileOut);
fileOut.close();

out of the method(int i), and then in the main method, we can use:

 sc.method(1); 
 sc.method(2); 
 FileOutputStream fileOut = new FileOutputStream("workbook.xlsx");
 workbook.write(fileOut);
 fileOut.close();

Then, the workbook.write is only used for once. Also the data could be modified several times.
