Execute .bat file from applet?


Can I execute a .bat file from Java applet?

I am trying execute a .bat file by using exec(String) method.

My code is:


        Process proceso;

        catch(IOException e)
            System.out.println("bad shell");

        System.out.println("The end");

It do not execute the command system 'tree', but it print "The end".

It is right if I do not use a bat file, like this:


Thank you,

Runtime.getRuntime.exec("command.com /c c:\\sistel\\ejemjava\pt\param.bat");

On NT, command.com would be cmd.exe, instead.  

I would like to know how to get at system environment variables from java.
