Please install the Beta 3 version of Flex Data Services. The
easiest way to get started is to install using the integrated
version of JRun.
However, it is possible to install on Tomcat with a few
additional updates. These updates are required because FDS takes
advantages of J2EE features, which are not available on Tomcat,
since it's not a full J2EE server.
If you would like to install on Tomcat, please see the
additional instructions -

please see the SQL admin sample application.
