Hi,
I’m trying to create a MUC from my Android code. Joining an existing MUC is OK.
Server is Openfire 3.6.4.
I get:
11-20 14:36:28.465 E/AndroidRuntime( 2008): java.lang.ClassCastException: org.jivesoftware.smack.packet.DefaultPacketExtension
11-20 14:36:28.465 E/AndroidRuntime( 2008): at org.jivesoftware.smackx.muc.MultiUserChat.getMUCUserExtension(MultiUserChat.jav a:1986)
11-20 14:36:28.465 E/AndroidRuntime( 2008): at org.jivesoftware.smackx.muc.MultiUserChat.create(MultiUserChat.java:350)
Sorry, got posted early.
Line 1986:
return (MUCUser) packet.getExtension(“x”, “http://jabber.org/protocol/muc#user”);
Line 350:
MUCUser mucUser = getMUCUserExtension(presence);
I logged the packet sent and received. The x element is empty:
11-20 15:06:13.985 D/MultiUserChat( 2049): send: joinPresence=
11-20 15:06:14.105 D/MultiUserChat( 2049): received: presence=
which causes packet.getExtension() to be null, which causes the ClassCastException.
When doing this in Pidgin:
4:04 You have connected
4:04 user1 [user1@xmpp.paraz.com/Migs-MacBook] entered the room.
4:04 This room is locked from entry until configuration is confirmed.
then a dialog appeared: Create new room … Would you like to configure it, or accept the default settings?
When Accept Defaults is chosen:
4:05 This room is now unlocked.
How do we do this using Smack?
me too，我也是MultiUserChat在android上的问题。请求答案中……
It’s a good chance that your smack.providers file is not on your classpath. This would result in the default provider being used instead of the specific MUC one.
Hi !
I have exactly the same problem (and the same error message) but my smack.providers is already in my META-INF folder, do you have any idea why I have this error ?
