In Linux, I am trying to give full permission (777) to a folder structure (say ex: "home/test/sample/") for creating a MySQL table with changing the data directory to the user specific location from my application which is written in Java.

How can I give full permission to a folder structure from Java?

Solution

  • You have to use a Operating System dependent code just like this:

        Runtime rt = Runtime.getRuntime();
    Process proc;
    int exitVal = -1;
    try {
        proc =  rt.exec("chmod 777 "+file);
        exitVal = proc.waitFor();
    } catch (Exception e) {}
