Question

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

muc= new MultiUserChat(HomeActivity.connection, "[e-mail]");
        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.
