Simple Example

[Flexspert]

Hi there!!



Any of you guys know a place where I can get practical
examples of Data Services development?

I want only a simple example in how to retrieve data from the
Data Services Server. I searched on the internet and only found
some examples using PHP/XML, but I would like to use Data Services.



It's being so hard to find information about data services
that we at our company are thinking about in use PHP/XML instead of
FDS, in our Flex Application.



Thanks!

Did you tried this testdrive ?

Hi kcell, I'm reading a tutorial that I got from the page you
indicated (
http://coenraets.org/tutorials/fdms_tutorial.pdf)
and realized that this example uses Data Services + JAVA as the
development envirnoment.



Now I'm more confused. I thought Data Services included it's
own programming language (maybe Actionscript 3). Do I have really
to use Java with Data Services?? Is it the only option I have? If
so, it'll be very difficult for us, cause we don't have a Java
Programmer. All we want to do is use Data Services to get some
simple data from the Server.



Thanks!

I am also a newbie to FDS (coming from the c++/c# corner) and
I just used the webservice proxy (as a simple router to a backend
ASP webservice), which means I didn´t code anything. I just
used the proxy (some configuration work , I was also lost without
the help from the forum here (thanks to Peter)).



If you just want to get simple data from a server you should
consider of getting it directly without the lifecycle/fds server.
(my reason was that our customer didn´t want a asp
webservice(IIS) outside there firewall)

With the flex framework you can easily access data via http
or webservice, but this depend on your data/system structure.



Finally (to answer your question ;) ) for some functionality
you can use directly a java application server+lifecycle/FDS and
for more advanced functions you can use java apps and frameworks
(hibernate, spring,...) to connect to a backend system/server.

The actionscript/mxml language is just used for the flash
client code (the swf file).

Before Flex 2 the FDS could also used to compile the SWF file
dynamically/at runtime, but this is no longer the main goal since
Flex 2.
