B4J Question Kill and restart a standalone .exe from another B4J app

[marcick]

Hi all,

as the title says, from a B4J app acting as a "watchdog" I would like to:

1. Check if another B4J app (built as a standalone .exe, not a .jar) is currently running.
2. If it is, be able to kill it.
3. Restart it afterwards.

This is running on Windows Server.
Any hints or sample code would be very appreciated.

You can use JarCaller to kill it: JarCaller - Run and kill B4J jars
Make sure to give the main app a unique package name.

Starting is simple with jShell. Just call the executable.

Thants, I saw that example.
No problem for starting with Jshell, but for killing it is not clear to me.
Once the package name is for example it.sample and the exe name in sample.exe, how to use that code that looks for jar ?

Try this:

Wait For (Caller.KillJavaProcess("it.sample.main")) Complete (Counter As Int)

Thank you. I discovered it is needed a B4j/ prefix:

Wait For (Caller.KillJavaProcess("b4j/it.sample.main")) Complete (Counter As Int)
