I've started playing around with Red5.
By the way, this is my first java application so please be tender.
What I want to do is to build a simple chat room, with private chat
(maybe video?)
The first doubt I got is:
Which one is the main difference between these methods?
appStart
appConnect
connect
appDisconnect
disconnect
What I saw in red5 log files is that the first method called is
"Connect", then comes "appConnect", but I never saw "appStart" (maybe
not logged)
Second, I've read about creating a new instance of the application to
make a chat room, at least that's what I got, For example, I have an
application rtmp://localhost/chat, to make more rooms I
need to create another instance under rtmp://localhost/chat/myRoom,
rtmp://localhost/chat/myOtherRoom, and so on?
And last but no least,
I'm trying to manage users in rooms without using Flash SharedObjects,
but inside the Java Application.
I do as follows:
private Vector<Object[]> users = new Vector<Object[]>();
@Override
public boolean connect (IConnection conn, IScope scope, Object [] params)
{
Log ("Connect");
if (params == null || params.length == 0)
{
rejectClient ("No username passed.");
}
if ( ! super.connect (conn, scope, params))
{
return false;
}
String username = params [0].toString ();
String uid = conn.getClient ().getId ();
if ( ! existUsername (username))
{
users.addElement (new Object []
{
new String (username ) , new String (uid )
} );
ServiceUtils.invokeOnAllConnections ("UpdateUserList", new Object []
{
users
});
}
else
{
rejectClient ("Username already token");
}
return true;
}
Here everything goes well, and when a user logs off:
@Override
public void disconnect (IConnection conn, IScope scope)
{
//ServiceUtils.invokeOnAllConnections( "UpdateUserList", new
Object[] {users});
Log ("Disconnect");
String uid = conn.getClient ().getId ();
if (uid != null)
{
for (int i = 0; i < users.size (); i ++)
{
if (uid.equals (users.elementAt (i)[1].toString ()))
{
Log ("Delete: " + users.elementAt (i)[1].toString ());
users.removeElementAt (i);
break;
}
}
}
else
{
super.disconnect (conn, scope);
}
}
but, with the line
ServiceUtils.invokeOnAllConnections( "UpdateUserList", new Object[]
{users});
the log fails with:
[java] [ERROR] 23875 IoWorker-1:( org.red5.server.Scope.error ) Error
while executing "disconnect" for connection RTMPMinaConnection from

Any ideas?
That's all folks :), thanks for your help.
