    java.lang.Runtime.exec fails on Mac
    Hi folks;
    I am developing a java program that needs to run commands as if it were from command line. I have a binary in /Applications/LabPrints/Image Aligner/LabPrints.dalp
    and when I run it from command line, it runs but when I try to run it form Java with
    String cmd="\"/Applications/LabPrints/Image Aligner/LabPrints.dalp\"";
    Runtime.exec(new String[]{cmd});
    I get an error with the output: "/Applications/LabPrints/Image Aligner/LabPrints.dalp": not found
    at java.lang.UNIXProcess.forkAndExec(Native Method)
    at java.lang.UNIXProcess.<init>(
    at java.lang.Runtime.execInternal(Native Method)
    at java.lang.Runtime.exec(
    at java.lang.Runtime.exec(
    at java.lang.Runtime.exec(
    at krs.MainClass.main(
    Does anyone has any idea what I am missing? I am running the same on PC and it runs perfectly. I am also capturing the output and error streams of the created process in separate threads.

    Thanks in advance...

    Try sending the command without the escaped quotes. The quotes are just to help the terminal identify the application path as a single argument. But when you send it with the quotes through the exec() method, it thinks the quotes are part of the filename.
