Launching external executable? [message #332118]

Hi,

For a certain scenario I need to launch an external executable (*.exe)
from within an RCP application.
I also need to have control of the launched process, e.g. get return
status etc.

Which is the most suiteable and recommended approach for this?
I've searched a lot about launching and basically all I've found deals
with Eclipse launch framework (i.e. creating ILaunchConfigurationType,
ILaunchConfiguration...).
But isn't this approach more applicable for run/debug activities during
development?
Or if needed to provide run/debug launch configuration UI to user?
Because this is not the case for me. I just need to launch an executable
and have proper control for that launched process.

BTW. I'm running on Windows platform.

Thanks in advance, need a quick answer!

Regards,
Joachim

I would have tried Runtime#exec. The return type is a Process object,
which has e.g. a method waitFor and a method exitValue....
