    Can you post the code that shows how you are calling javac?

    here is the code
    public static void compileFiles(String path)
    {
    System.out.println("Class Creation Started");
    try
    {
    Process rt =Runtime.getRuntime().exec("cmd /c start /min javac "+ path +"\\*.java");

    rt.waitFor();
    System.out.println("exitvalue:" +rt.exitValue());
    }
    catch (Exception e) {System.out.println("Unexpected exception Trying to Execute Job: " +e);}

    System.out.println("Class Creation Ended");
    }

    Have you tried executing javac directly instead of using cmd?

    Also there is a class that will do a compile via method calls.
    See the API doc for the JavaCompiler interface.

    you need to specify the full path, not just the directory and the file name to create a file or even check it's existence. I am sure they helps you.
