Rlogin and subsequent IO communication issue

Question

My application has to use runtime.exec to login to a remote server from a unix environment.
The call to echo out the response hangs.
Here is the code
            Process itests =
                Runtime.getRuntime().exec("rlogin -l uname tgtSrver ");          
            InputStreamReader isr = new InputStreamReader(itests.getInputStream());
            BufferedReader fromPkMts = new BufferedReader(isr);
            OutputStreamWriter osw =
                new OutputStreamWriter(itests.getOutputStream());
            BufferedWriter toPkMts = new BufferedWriter(osw);
            String Line = "";
            while((Line = fromPkMts.readLine()) != null){
                System.out.println(Line);
            }
