ActiveMQ has all of those features; they are all done by the ActiveMQ  

Unfortunately right now the integration of ActiveMQ into Geronimo is  
done via a few really basic GBeans which don't have the capability to  
configure all the clustering & failover options in ActiveMQ broker.  
Today the simplest option is just to run the ActiveMQ broker outside  
of Geronimo and just use the JMS client / JMS Resource Adapter / RAR  
inside Geronimo. However as we integrate the latest 4.x of ActiveMQ  
into Geronimo we hope to address this to make things fully  
configurable from inside Geronimo
