Replace your code with this . I have used this code its running fine.

public int offlinemessagecount(){
    try {

        ServiceDiscoveryManager manager = ServiceDiscoveryManager
                .getInstanceFor(connection);
        DiscoverInfo info = manager.discoverInfo(null,
                "http://jabber.org/protocol/offline");
        Form extendedInfo = Form.getFormFrom(info);
        if (extendedInfo != null) {
            String value = extendedInfo.getField("number_of_messages")
                    .getValues().next();

            return Integer.parseInt(value);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return 0;

}
