rlogin and subsequent IO communication issue

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);

}
