title: I don't see output in Console, System.out.println issue in Liferay
body: <p>I use Liferay portlet bundle 6.2 (Tomcat), I save some variable in portlet preference. It's going on without problem, but if I print the entries with <code>System.out.println</code>, it doesn't come a output on console. Where comes output with <code>System.out.println</code> in Liferay? How I can work with <code>System.out.println</code> in Liferay, is there another solution instead of <code>System.out.println</code>?</p>
  
  <p>In follow I post the code, where comes </p>
  
  <p>Thank you</p>
  
  <pre><code>    public void addEntry(ActionRequest request, ActionResponse response) {
  
      try {
  
         PortletPreferences prefs = request.getPreferences();
         String[] guestbookEntries = prefs.getValues("guestbook-entries",
            new String[1]);
  
         ArrayList&lt;String&gt; entries = new ArrayList&lt;String&gt;();
  
         if (guestbookEntries != null) {
  
           entries = new ArrayList&lt;String&gt;(Arrays.asList(prefs.getValues(
                "guestbook-entries", new String[1])));
         }
  
         String userName = ParamUtil.getString(request, "name");
         String message = ParamUtil.getString(request, "message");
         String customer = ParamUtil.getString(request, "customer");
         String entry = userName + "^" + message + "^" + customer;
  
         entries.add(entry);
  
         System.out.println("hallo");
  
         String[] array = entries.toArray(new String[entries.size()]);
