Java Programming

hi,

my application need that some operations (environment variables are stetted, and a database server manager)
are executed before it runs.

If I use a DOS window to realize manually this purpose the application works fine.
I would, however, that the application runs automatically without these operations are manually made.

For realize this purpose I would that some .bat files are made execute from the java code,
and I tried to do it in this way:

        String command = "C:\\path\\commandFile.bat";

        Runtime runtime = Runtime.getRuntime();
        try {
            runtime.exec(command );
            System.out.println("Ok !!! : ");
        } catch (IOException ex) {
        System.out.println("IOexception : " + ex.getMessage());

but I didn't get any result
(i.e. neither a DOS window raised, neither the server started)

I would like have some help about how to do it..

any help is welcome.

thank you, regards
