Smack, Getting Error in creating new MultiChat

Question

I am using asmack for creating a chat app. For creating a MultiUserChat i am using following code.

muc= new MultiUserChat(HomeActivity.connection, "chatRoom@conference.live-images.com");
        try 
        {
            muc.create(HomeActivity.connection.getUser());
            muc.sendConfigurationForm(new Form(Form.TYPE_SUBMIT));


               muc.join("kam");
        } 
        catch (XMPPException e) 
        {
            e.printStackTrace();
        }

But i an getting the error.

Class CastException. & if i remove the Confrence from new MUC() then I get Server Not Responsing Error.

Where i am wrong? Do i have to use some Patch.

it would be better to send more details like the stack trace. Make sure you follow the code example here: Multi User Chat
