No, in fact I really have a problem:
public boolean appJoin(IClient client, IScope app){
System.out.println("App joined by");
System.out.println(client.getAttribute("name"));
//for every connections i have on this scope
Iterator<IConnection> connections = app.getConnections();
while(connections.hasNext()){
System.out.println("into appjoin...");
IConnection conn = connections.next();
IServiceCapableConnection service = (IServiceCapableConnection)
conn;
// I want to send the new client name to clients
service.invoke ("addUserToList",new Object[]{client.getAttribute
("name")});
}
return true;
}
This is strange but Client1 connect: I see "App join by Client1" and de
"addUserToList" isn't called
I add Client2, I see "App joined by Client2", now Client1 receive "Client1"
in "addToUserList"
I add Client3, I see "App joined by Client3", now Client1 receive "Client1"
(again) in "addToUserList" and Client2 receive "Client2"...
I dont understand why, please help...
