I am running long computations (run time measured in days) and I am saving the results to an Excel worksheet using the JExcel API. I would like to save the results to disk at regular intervals to prevent any loss of data due to, say, power outages or unforeseen computer crashes.

My question is : how do I go about doing this in a reasonable way? Only calling write() in WritableWorkbook does not work, and closing the work book using close() would require reopening the work book afterwards which is pretty cumbersome. Any ideas?

  • Do you use the [`JExcel API`](http://www.teamdev.com/jexcel) (i.e. the API of `JExcel`) or the [`JExcelApi`](http://jexcelapi.sourceforge.net/)? – wolfrevo Feb 27 '14 at 09:08
  • I assume you use JExcelApi. What did you tried? Did you wrote some code? – wolfrevo Feb 27 '14 at 09:24
