ActiveMQ HTTP protocol support in ActiveMQ 4.1.1 is in the activemq- 
optional-4.1.1.jar. Geronimo does not include this jar in our  
distributions.

If we did include the optional jar (or if you hacked the activemq- 
optional classes into the activemq-core-4.1.1.jar file that we do  
include), you could update your var/config/config.xml and add the  
following new GBean to the activemq-broker module:

         <gbean name="org.apache.geronimo.configs/activemq-broker/2.1/ 
car?ServiceModule=org.apache.geronimo.configs/activemq-broker/2.1/ 
car,j2eeType=GBean,name=ActiveMQ.http.default"  
gbeanInfo="org.apache.geronimo.activemq.TransportConnectorGBeanImpl">
             <attribute name="protocol">http</attribute>
             <attribute name="host">${ServerHostname}</attribute>
             <attribute name="port">58585</attribute>
             <reference name="brokerService">
               <pattern>
                 <groupId>org.apache.geronimo.configs</groupId>
                 <artifactId>activemq-broker</artifactId>
                 <version>2.1</version>
                 <type>car</type>
                 <name>ActiveMQ</name>
               </pattern>
             </reference>
         </gbean>

Note that I haven't tested this with activemq-optional classes. I have  
tested to the point of getting a "Transport scheme NOT recognized:  
[http]" exception from ActiveMQ.

Or, you could also build G 2.1 from source (this is a cleaner  
solution). Ignore the above and do something like the following:

pom.xml -- search for 'activemq-core' and create equivalent stanza for  
activemq-optional
plugins/activemq/activemq-broker/pom.xml -- ditto
plugins/activemq/activemq-broker/src/main/plan/plan.xml -- duplicate  
either the "ActiveMQ.tcp.default" or stomp GBean declaration and  
create a new "ActiveMQ.http.default" equivalent

Build Geronimo.

That's all untested...
