Soumya, If you start ServiceMix with the servicemix.bat file as you are doing, without changing any of the configuration files, it will run an ActiveMQ broker inside ServiceMix. You can use it as a JMS broker for the JMS endpoints, but we also use it internally for e.g. the wsn2005 component or when you use the JMS/JCA flow. By default, the embedded ActiveMQ instance is configured to use multicast discovery, so it will send out multicast packets to find other ActiveMQ instances on the network and automatically connect to those. The conf/activemq.xml is basically just an ActiveMQ configuration file, so you can use whatever type of configuration you find on http://activemq.apache.org in there (clustering, failover, ...)
Concerning Apache Geronimo: that is an open-source application server which can be extended by using Geronimo plugins. We have such a plugin for ServiceMix, allowing you to run ServiceMix inside Geronimo. However, if you just run the standard distribution, you are not using Geronimo at all. It's just the JBI container with the embedded ActiveMQ broker then. Also, this is just for ServiceMix 3 : we don't have support for embedding ServiceMix 4 inside Geronimo yet, but this should be a far less common requirement for ServiceMix 4 because it is based on OSGi so you can integrate things at the OSGi level there.
