Get a list of all sessions of an application

Hello!

we use Enhydra 5 for a intranet project. I want to display a page with all 
currently connected users (=sessions) and tried the code below.
The problem ist that in the method activeSessions() I get all sessionskeys but 
sm.getSession(key) returns only the calling session and null for every other.
When I register my thread using Enhydra.register(), the result is the same.

So any solution?

------------------------------------------------
  private Vector activeSessions() {
      Vector sessions = new Vector();
      try{
          StandardSessionManager sm = (StandardSessionManager) 
Enhydra.getSessionManager();
          Enumeration keys = sm.getSessionKeys();
          while(keys.hasMoreElements()) {
            sessions.addElement(sm.getSession((String) keys.nextElement()));
          }
      } catch (Exception ex) {
        // log it
      }
      return sessions;
  }

To get the session listing
    Enhydra.register(Thread.currentThread(), getComms().application);
    try{
      sessions = activeSessions();
    } finally {
      Enhydra.unRegister(Thread.currentThread());
    }
