Excel cell background colour in POI

Question

hi all,
i know this probably isnt the right place to post this but has anyone used the POI package to read Excel files?
Im trying to get the background colour of a cell
using
HSSFCellStyle bgCol=checkCell.getCellStyle();
String myCol=String.valueOf(bgCol.getFillBackgroundColor());but it doesnt return my colour index as it just returns 64 or 65
(it returns 64 if there is a colour background and 65 if there isnt a colour background, but always returns 64 regardless of the background colour)
any ideas why it does this and how i actually do get the unique identifyer of the colour.

Answer 1

this is my code
int maxRows=sheet.getPhysicalNumberOfRows();
for (int i=0;i<maxRows;i++)
     //check background colour
     HSSFRow checkRow = sheet.getRow(i);
     HSSFCell checkCell = checkRow.getCell((short)0);
     HSSFCellStyle bgCol=checkCell.getCellStyle();
     String myCol=String.valueOf(bgCol.getFillBackgroundColor());
     System.out.println(i+" "+myCol+ " : "+checkCell.getNumericCellValue()+" "+bgCol.getFillPattern());     
     }my first 3 rows in my sheet have 3 different colour backgrounds then the rest of 30 rows have no colour
the returned data looks like this
0 64 : 1.0 1
1 64 : 2.0 1
2 64 : 3.0 1
3 65 : 4.0 0
4 65 : 5.0 0
5 65 : 6.0 0
6 65 : 7.0 0
7 65 : 8.0 0
8 65 : 9.0 0
9 65 : 10.0 0
10 65 : 11.0 0
11 65 : 12.0 0
12 65 : 13.0 0
13 65 : 14.0 0
14 65 : 15.0 0
15 65 : 16.0 0
16 65 : 17.0 0
17 65 : 18.0 0
18 65 : 19.0 0
19 65 : 20.0 0
20 65 : 21.0 0
21 65 : 22.0 0
22 65 : 23.0 0
23 65 : 24.0 0
24 65 : 25.0 0
25 65 : 26.0 0
26 65 : 27.0 0
27 65 : 28.0 0
28 65 : 29.0 0
29 65 : 30.0 0
as you can see the getFillBackgroundColor() is not returning the right stuff
