New user: Synapse as a Web Application in Tomcat (war)

[Sanoran Triamesh]

Hi,
  I new to Synapse. I would like to use it as a 'web application' in an
existing tomcat.Currently I use the axis2.war, and deploy it in tomcat.
  Is Synapse a 'service' inside axis2 ? Is there a list of libraries and
the service so I can create my 'synapse.aar' ?

Thanks
S.
