Question

I am using

java.awt.Desktop.getDesktop().browse(uri);

to show my users a generated html file. All is fine if the browser (firefox 3.5.7; linux) is started before I make the call. But if the browser start is triggered from the getDesktop().browse call then the java application will not exit until the browser closes.

How can I avoid this behaviour? Is this known under windows/macOsx too?

(If I then force the exit of the java application the browser will close too and sometime even crash!?)

Answer 1

The reason the browser exists is because the browser is launched as a dependent process…so when the first process shuts down, all its dependent processes are shut down with it. But in the case when you start the browser first, it already has a different process ID that isn’t affected by your application. I think the only way to avoid this behavior is to use a different technique (perhaps Runtime.exec()?) to launch the browser in a way that registers it as a non-dependent process.
