Hi,
FDS is now LiveCycle Data Services (LCDS). Please find more
details on LCDS at the URL below. You can also have a look at
BlazeDS, which is a free and open source version on LCDS. Please
find more details on BlazeDS at the URL below.
All said BlazeDS/LCDS is for Java based back ends. If you are
using PHP and need to get the power of Remoting and other you can
try AMFPHP.
Regarding servers, you can use Apache Tomcat/JBoss/Jrun4 for
Java as the server side technology. If you are using PHP as the
server side technology then you might have to configure the servers
mentioned above a little bit to get the PHP scripts executed.
BlazeDS/LCDS is not a server.
