Write data to SharePoint from embeded Flex swf

Question

I am trying to integrate Flex 3 applications into SharePoint 2007 environment which would allow our users to read/write/delete data from SharePoint using an embeded Flex app inside SharePoint. While the article from matthew.meier on "Adding Event Driven Flex Components to Microsoft Sharepoint 2007" is great and another article by Serge van den Oever on "Use Flex to retrieve data from a SharePoint list" is fantastic, they neither touch the topics of writing or inserting data into SharePoint. My goal is to create a two-way communication between Flex and SharePoint to dynamically pull (read) data into Flex  from SharePoint lists, etc via GUID or other method AND to also write or update SharePoint from a front-end Flex inside SharePoint.

Answer 1

I have been working on a solution which appears like it would work, but I am getting errors. The source code and examples are found on Code Project http://www.codeproject.com/KB/aspnet/FlexASPWebService.aspx?msg=3270246#xx3270246xx This Flex/ASP example uses a web service to communicate to a SQL database. Flex makes a web service call to the .asmx file via WSDL and the magic happens. I am running into a roadblock as I receive an error that the app cannot find the WSDL. I have tried to run the same WSDL URL in a browser and I get an server application error.
I also tried a solution found at http://shardulbartwal.wordpress.com/2008/03/20/import-web-servicewsdl-wizard-in-flex-30/ to load the WSDL file directly into Flex, but I ran into another roadblock. When I get to this step below Flex gives an error that it cannot find the WSDL file either…
Here is the WebService call from Flex…
The files from Code Project contain a directory structure as such:
TestWebService\Service.asmx
TestWebService\Web.config
TestWebService\App_Code
TestWebService\App_Code\Service.cs
TestWebService\App_Data
The Service.cs file is inside the App_Code directory and is referenced from the Service.asmx file with this code:
My Flex file calls the Service.asmx?WSDL which then calls the file Service.cs and then it breaks.
The Code for the Flex file is as follows…
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()">

The Flex app error states it cannot locate the WSDL. Any ideas?
I don’t know what I am doing wrong…
