Opening an Excel file using the default program

Question

My program successfully creates and fills a Excel(.xls) file. Once created, I would like the new file to open in the system\'s default program (Excel in my case). How can I

Answer 1

You probably did the Runtime.exec incorrectly. Give this a look to see if that's the case.

If you just want to open an Excel file with Java, I'd recommend using Andy Khan's JExcel API. Perhaps using that with a Swing JTable will be just the ticket.

Answer 2

The most simple and efficient way.

Desktop.getDesktop().open(new File("inputFilePath"));

Answer 3

Try to use Desktop.open() instead of Desktop.edit() :

Desktop dt = Desktop.getDesktop();
dt.open(new File(this.outputFilePath));

If Desktop.open() is not available then the Windows file association can be used :

Process p = 
  Runtime.getRuntime()
   .exec("rundll32 url.dll,FileProtocolHandler " + this.outputFilePath);
