Created attachment 35728
--> https://bz.apache.org/bugzilla/attachment.cgi?id=35728&action=edit
test-File like the original
code that causes the bug:
public void dateiSpeichern(){
try (FileOutputStream outPutStream = new
FileOutputStream(actualFile)){
System.out.println("File: "+actualFile);
System.out.println("Sheet:
"+actualSheet.getSheetName());
//Daten abspeichern
Header header=actualSheet.getHeader();
header.setLeft(jtaZeitraum.getText());
header.setCenter(jtaAnschrift.getText());;
header.setRight(jtaVonBis.getText());
for(int i=0; i<datensatzListe.size(); i++){
XSSFRow row=actualSheet.getRow(i+3);
System.out.println("Row: "+row.getRowNum());
XSSFCell cell0=row.getCell(0);
cell0.setCellValue("");
XSSFCell cell1=row.getCell(1);
cell1.setCellValue("");
XSSFCell cell2=row.getCell(2);
cell2.setCellValue("");
XSSFCell cell3=row.getCell(3);
cell3.setCellValue("");
XSSFCell cell4=row.getCell(4);
cell4.setCellValue("");
XSSFCell cell5=row.getCell(5);
cell5.setCellValue("");
XSSFCell cell6=row.getCell(6);
cell6.setCellValue("");
XSSFCell cell7=row.getCell(7);
cell7.setCellValue("");
XSSFCell cell8=row.getCell(8);
cell8.setCellValue("");
XSSFCell cell9=row.getCell(9);
cell9.setCellValue("");
XSSFCell cell10=row.getCell(10);
cell10.setCellValue("");
}
for(int i=0; i<datensatzListe.size(); i++){
XSSFRow row=actualSheet.getRow(i+3);
System.out.println("Row: "+row.getRowNum());
XSSFCell cell0=row.getCell(0);
System.out.println("Cell:
"+cell0.getColumnIndex());
cell0.setCellValue(datensatzListe.get(i).getEinnahmen());
XSSFCell cell1=row.getCell(1);
cell1.setCellValue(datensatzListe.get(i).getMwstEin());
XSSFCell cell2=row.getCell(2);
cell2.setCellValue(datensatzListe.get(i).getAusgaben());
XSSFCell cell3=row.getCell(3);
cell3.setCellValue(datensatzListe.get(i).getMwst19Aus());
XSSFCell cell4=row.getCell(4);
cell4.setCellValue(datensatzListe.get(i).getMwst7Aus());
XSSFCell cell5=row.getCell(5);
cell5.setCellValue(datensatzListe.get(i).getRechnr());
XSSFCell cell6=row.getCell(6);
cell6.setCellValue(datensatzListe.get(i).getZaehler());
XSSFCell cell7=row.getCell(7);
cell7.setCellValue(datensatzListe.get(i).getDate());
XSSFCell cell8=row.getCell(8);
cell8.setCellValue(datensatzListe.get(i).getVonFuer());
XSSFCell cell9=row.getCell(9);
cell9.setCellValue(datensatzListe.get(i).getRubrik());
XSSFCell cell10=row.getCell(10);
cell10.setCellValue(datensatzListe.get(i).getKonto());
}
tabelleAktualisieren();
actualWB.write(outPutStream);
outPutStream.flush();
outPutStream.close();
writerEx.flushFileWriter();
} catch (IOException e) {
e.printStackTrace();
writerEx.printIOException(e);
} catch (NullPointerException e1) {
e1.printStackTrace();
writerEx.printNullPointerException(e1);
} catch (Exception e2) {
e2.printStackTrace();
writerEx.printException(e2);
}finally{
}
}

There doesn't seem to be any Apache POI code involved in your stacktrace.
Therefore, it rather seems to be a bug in your code...
Can you write a short junit unit test case (or similar standalone program)
which shows the issue to be in POI?

--- Comment #3 from PJ Fanning <fa...@yahoo.com> ---
Markus - the NullPointerException is in your code, not in Apache POI.
Line 42 in your code is
cell0=row.getCell(0);
So most likely the row is null.
I opened the xlsx file in your zip and the sheet called `test` is empty - which
might explain why getRow for that sheet is returning null.
