  <title>What is ServiceMix 3 ?</title>

  <para>
    Apache ServiceMix is an open source ESB (Enterprise Service Bus) that combines the functionality of a Service Oriented Architecture (SOA)
    and an Event Driven Architecture (EDA) to create an agile, enterprise ESB.
  </para>
  
  <para>
    Apache ServiceMix is an open source distributed ESB built from the ground up on the Java Business Integration (JBI) specification JSR-208
    and released under the Apache license. The goal of JBI is to allow components and services to be integrated in a vendor independant way,
    allowing users and vendors to plug and play.
  </para>
  
  <para>
    Apache ServiceMix is lightweight and easily embeddable, has integrated Spring support and can be run at the edge of the network (inside a client
    or a server), as a standalone ESB provider or as a service within another ESB. You can use ServiceMix in Java SE or a Java EE application
    server.
  </para>
  
  <para>
    Apache ServiceMix uses Apache ActiveMQ to provide remoting, clustering, reliability and distributed failover.
  </para>
  
  <para>
    Apache ServiceMix is completely integrated into Apache Geronimo, which allows you to deploy JBI components and services directly into Geronimo.
    ServiceMix is being JBI certified as part of the Geronimo project.
  </para>
  
  <para>
    Other JEE application servers Apache ServiceMix has been integrated with include JBoss, JOnAS with more to follow.
  </para>
  
  <para>
