Problem while writing data on xls file using jxl API

Question

Hi,
I am getting problem while writing data on excel file using jxl api.
When i write data on file and all handles associated to the file are closed, file size increases but when i open the file nothing is written in it and when file is closed manually from excel window, file size decreased to its original that was before writing data.
here is code:
          FileOutputStream os = new FileOutputStream(this.dirPath + this.fileName, true);
          WritableWorkbook this.workbook = Workbook.createWorkbook(os);
after writing data following handler are closed:
this.os.flush();
                    this.workbook.write();
                    this.workbook.close();
                    this.os.close();
                    this.os = null;
can any body help me.
Thanks in advance

Err, I did help you. I did understand your problem; and I solved it for you. What was missing was that you apparently made no effort to understand what you were being told. Or even consider it. You just argued about it, as though you were the one with the solution, instead of the one whose code didn't work.
And the other thing that was missing was the part where you said 'thank you' to me for solving your problem. Somewhat more appropriate than biting the hand that fed you, frankly. I do this for nothing, on my own gas, and it's extremely irritating when people keep asking about problems I have already solved for them. I am entitled to discourage that. It's part of making them more efficient actually.
But it happens often enough that it also makes me think I'm just wasting my time. Probably I am.
