Question

I am trying to run an external program Decoder.exe using a java:
Runtime.getRuntime().exec(“C:\fullpath-and-so-on\Decoder.exe -h”); like so:

    try{
        Process p = Runtime.getRuntime().exec("C:\\fullpath-and-so-on\\Decoder.exe -h");
    }
    catch(Exception e){
        e.printStackTrace();
    }

This works for all other programs I’ve tried. But whenever I execute it from java the Decoder.exe crashes. The java executes fine and does not generate any exceptions but the called program Decodes.exe stops working. The program Decoder.exe executes perfectly when run in a separate cmd window.

Have anyone had any experience with a similar problem? What differs when java runs exec and when a program is run in cmd.exe? Is there a known workaround or am I just making a mistake somewhere?

Very thankful for any help!
BR,
Fredrik
