I’m trying to develop a chat client using Smack api with Openfire. I’ve been searching for couple of days on how to retrieve all users from Openfire. I tried adding all the users to a group and tried fetching it :
Roster roster = conn.getRoster();
RosterGroup grp = roster.getGroup("GroupName");
Collection<RosterEntry> ent = grp.getEntries();
for(RosterEntry rosEnt : ent){
System.out.println(rosEnt.getUser());
}
But this prints only the current user. I also noticed something called Shared Group but did not know how to create one. Is there a way to fetch all users?
I also tried using
UserManager.getInstance().getUsers();
but it gave exception :
Critical Error! The home directory has not been configured,
which will prevent the application from working correctly.
log4j:WARN No appenders could be found for logger (org.jivesoftware.util.JiveGlobals).
