B4J Question Call non-ui app (.jar) with parameter from another app

I presume you mean call a b4j-jar direct from another app. In that case, use that program's shell abilities to call

Inside AppStart() of MyJar.jar, arg1, arg2 and arg3 will appear as elements in the Args() As String parameter. Inside MyJar.jar, anything you put inside Log() will be printed to Standard Out. If the calling program has the ability to capture Standard Out of shell commands it executes than it should be able to see MyJar.jar's output. B4J's jShell library has this capability.

You can find the path to java with this line:

It will work on all platforms.
