Some substring doubts

Question

Hi all!!
I am almost finishing my app, but i have a line like below:
[2003/12/09 16:43:48.165] [info] br.com.organox.web.aggregator.servlet.struts.action.AddContentAction: User 'INEXIST' with session 'ax1zjd8yEeHh' added content '769' with uri 'http://mail.yahoo.com/'.
where i need to get the User (INEXIST in this case), the session (ax1zjd8yEeHh) and the action (added content '769' with uri 'http://mail.yahoo.com/'. In this case)
how i must proceed? I�m getting some wrong results using substring
Thanks

You gotta love regex...
String test = "[2003/12/09 16:43:48.165] [info] br.com.organox.web.aggregator.servlet.struts.action.AddContentAction: User 'INEXIST' with session 'ax1zjd8yEeHh' added content '769' with uri 'http://mail.yahoo.com/'";
String pattern = "^.*User\\s'(\\w+?)'.*session\\s'(\\w+?)'\\s(.*)$";
Pattern p = Pattern.compile(pattern);
Matcher m = p.matcher(test);
if (m.find()) {
    String user = m.group(1);
    String session = m.group(2);
    String action = m.group(3);
    System.out.println("User:    " + user);
    System.out.println("Session: " + session);
    System.out.println("Action:  " + action);
