I am using Apache POI 3.6 to generate excel (2003) sheets. I want to insert a formula to a cell which calculates a sum of a certain cells on several sheets.
I have sheets named a, b and c and want to calculate the sum the cells A1
I tried:
cell.setCellFormula("a!A1+b!A1+c!A1");
POI does not produce any errors, but when I open the sheet I get an error in OpenOffice:
Err: 522 - =$#REF!.A1+$#REF!.A1+$#REF!.A1
I did a bit of research and apparently there are bugs when referencing multiple sheets. (eg https://issues.apache.org/bugzilla/show_bug.cgi?id=46670) Does anyone have an idea how to use formulas using multiple sheets in POI?

createVal(sheet1, createHelper, 5);
createVal(sheet2, createHelper, 10);
createVal(sheet3, createHelper, 15);
createVal(sheet4, createHelper, 20);
try {
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
System.out.println("done");
} catch (IOException e) {
e.printStackTrace();

public static void createVal(Sheet sheet, CreationHelper createHelper, int i){
Row row = sheet.createRow((short)0);
// Create a cell and put a value in it.
Cell cell = row.createCell(0);
// Or do it on one line.
row.createCell(0).setCellValue(i);
