Please take a look at the discussion here:

https://collaborate.pega.com/question/how-can-i-execute-shell-script-prpc

It is basically the same question (but for .sh files on *nix, rather than .bat files on Windows).

I'm trying to do the same thing.  The logic in the .sh post is not working as a .bat.  I've tried several ways to get it to run.  Any help is appreciated.  I'm using PRPC 7.1.8.

Logic 1

Logic 2

String path="cmd /c start d:\\DEV\\Forms\\PrintPageToPDF_F-9015.bat";
Runtime rn=Runtime.getRuntime();
Process pr=rn.exec(path);

Logic 3

String[] cmdArray = new String[3];
cmdArray[0] = "cmd.exe";
cmdArray[1] = "/c";
cmdArray[2] = "d:\\DEV\\Forms\\PrintPageToPDF_F-9015.bat";
Runtime.getRuntime().exec(cmdArray);
