What happened to the http protocoll in ActiveMQ 4.0

[mail]

Hi,

when I execute the following with activemq-4.0M4,

public static void main(String[] args) throws Exception {
   BrokerService broker = new BrokerService();
   broker.addConnector("http://localhost:8081";);
   broker.start();
}

I get the message:

Exception in thread "main" java.io.IOException: Transport scheme NOT 
recognized: [http]

How do I do http-tunneling in ActiveMQ 4.0
