set execute permition on file

Question

I need to set execute permition on Linux script file using java 1.4. I would prefer to use java native library. If it is not possible with native library what is lightweight lib that allows to do it?

JAVA5 and prior there is workaround using exec extracted from here:

public static void runCmd (String[] cmd) {

    try {
        Process p = Runtime.getRuntime().exec(cmd);
        BufferedReader r = new BufferedReader(
            new InputStreamReader (
                p.getInputStream()
            )
        );
    } catch(Exception e) {
    }
}

USE

runCmd(new String[] {
    "/bin/chmod",
    "755",
    "/path/to/your/script"
});

By terminal in Linux

UP TO JAVA6
For permissions use File::setExecutable(boolean [, boolean])

File file = new File("/your/path/to/file/file_script.sh");
file.setExecutable(true);

Does it work for Java versions prior 1.6? – Stanislav Sep 08 '15 at 08:36
Yes in `Java6`, not in `Java5`. But [here](http://stackoverflow.com/questions/11095728/set-file-permission-in-java-5) you can find a workaround for `Java5` – Jordi Castilla Sep 08 '15 at 08:40
