No, Flex Data Services (FDS) which is now called Livecycle
Data Services (LCDS) is a seperate installation.
FDS/LCDS is a J2EE application and hence you need a J2EE
server to run it such as JRun, JBoss, Websphere, Weblogic, and so
on.
I suggest you run through Christophe's FDS tutorial to get a
better understanding of FDS/LCDS:
