I have created a new excell workbook using
WritableWorkbook workbook = Workbook.createWorkbook(file);
Then I have writen it and closed. Now I want to get that workbook by file name to write - not read only- some new data to it. I found that I can get the workbook by
Workbook workbook = Workbook.getWorkbook(file).
But it is read only. What I want is get - not create - a writable workbook that have already written.
