When a JasperViewer appear and I close it, the main frame/parent also closed [duplicate]

Answer 1

Change this: JasperViewer.viewReport(jasperPrint);

to JasperViewer.viewReport(jasperPrint, false); This will work properly.

Answer 2

JasperViewer(jasperPrint, false);    

You just have to pass false with jasperviewer so the parent window won't close.

Answer 3

Change:

JasperViewer.viewReport(jasperPrint);

To:

JasperViewer.viewReport(jasperPrint);
JasperViewer.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

It would seem theJasperViewer is using JFrame.EXIT_ON_CLOSE which will cause System.exit(n) to be called, thus ending the JVM.

By using JFrame.DISPOSE_ON_CLOSE instead, only that frame is ended & disposed of.

Answer 4

No need to do anything, other than to call the alternative:

JasperViewer(jasperPrint, **false**);
JasperViewer.viewReport(jasperPrint, **isExitOnClose**);

The JasperViewer has alternative constructor/method call which receives boolean param: exitOnClose

I don't know if you've found your own way around but I think this is the best one.
