Works like a charm now, probably like you said something else in my code
(although it compiled fine)..

Thanks.

Well, I just tested it, and this ...

       int yourInt;
    String yourString = "A string that contains number 30 that needs to
be parsed out";
    Pattern p = Pattern.compile("\\d+");
    Matcher m = p.matcher(yourString);
    if(m.find()){
       yourInt =
Integer.parseInt(yourString.substring(m.start(),m.end()));
       System.out.println("yourInt="+yourInt);
    }else{
       System.out.println("hey, doesn't work!");
       // take your action in case no integer found in yourString
    }

... works perfectly fine.
Probably something else that does not work in your code.

Cheers
Frans
