Flex And LCDS

[Former Community Member]

Hello,



For futur development, we need to choose a new Web oriented solution.

Flex look's like as we need because it's open source, Cross-platform,

AIR (deploy applications to the desktop), develop by Adobe, ...



When i'm look on Adobe's solutions, i'm quickly lose :  Flex, LiveCycle

Data Services Flex Data services, ColdFusion, ... plus components like AMFPHP.

So, I don't know what i need.



We want :

- Use PostgreSQL 8 as RDBMS,

- Flex as client,

- Connected mode (sessions management),

- Data push

...



If it's possible, we want it without any server-side language (PHP, Java, ...)

or use it as less as possible.



On Web, there is a lot's of example but when we search database connection ...



Cordially,

I would suggest looking into using Flex with LCDS 2.5.1 and its SQLAssembler

feature for Data Services where you can configure a destination and simply

provide the SQL for creating, retrieving, updating and deleting items directly

in the configuration - so no server side code to be written.

Thank you for your answer,



Is what the management of persistence and sessions with LCDS is

possible? (without using java/tomcat/hibernate...)

Hi All,



I would like to build an Flex/AIR application that initially provides LDAP authentication.



I am new to these Flex/Actionscript/DataServices however I have managed to get a nice datagrid querying & updating a MySQL Db from a Flex App using AmfPHP... Nice. I'm learning :-)



My question at the moment is what is the best/easiest way to enable LDAP authentication?



Could I use the following setup?

Flex/AIR IDE, LiveCycle Data Services ES Express, LDAP server?



Or do I NEED a j2SE server in there somewhere? or even a Coldfusion server?

I would like to try and avoid the need to include j2SE or Coldfusion servers at this stage.



Hope this makes sense.



TIA

Danny



PS: Thought I'd started a new thread, as I didnt I will re-post (apologies if I shouldn't)
