Hi,
Try this

 public static ArrayList getListFromTextArea(String textAreaValue){
       ArrayList list = new ArrayList();
       StringTokenizer tokens = new StringTokenizer(textAreaValue,"\n");
       while(tokens.hasMoreTokens()){
           list.add(tokens.nextElement());
       }
       System.out.println(list);
       return list;
   }

Cheers
Venu

StringTokenizer isn't encouraged in new code (see it's API doc page). The split() method in String is recommended instead:

String[] pieces = textAreaValue.split( "\n" );
List<String> list = Arrays.asList( pieces );

Did anyone find a reason, appart from the Sun's one (don't use it because I say it) to avoid StringTokenizer?
