Bringing Data into Flex - Crossdomain Problem

[RedaKechouri]

Hi,

I have a big problem with my flex app, I believe it is a security issue but I am still puzzled of how I can resolve it.
Basically, I have created a widget which lets the user select an area, a start date and an end date. Then, my widget creates an URL with those parameters (Start Date, End Date, List of Features of a specific dataset selected in the area), and sends this URL (with mx:HTTPService). This URL creates a csv file which retrieves all the queried information from an Oracle BI Server. So my flex widget retrieves this csv, parse it and then creates a nice graph wich corresponds to what the user wanted to see.

The problem is that everything works fine when I launch the app locally from Flex Builder, but I get the famous "Sandbox Violation Error" in my widget instead of the graph when I access my flex app from an URL.
This is typically a crossdomain kind of error, but even though I put the crossdomain file on the server where my flex app is located and added a "Security.loadPolicyFile()" in my index.mxml, it still doesn't work (and I verified that the crossdomain.xml was indeed accessible).

Any help would be appreciated

The crossdoamin.xml file should be on the server you're trying to access. For example, if the url you're calling is: http://server1/foo/service.jsp, then the Flash Player is going to try and load http://server1/crossdomain.xml

What is the full error message you're getting? If you use a tool like Charles, Firebug or HttpFox, then you can see what requests are being sent from your browser and look for the crossdomain.xml requests.

Many thanks for your answer,

We've tried to put a crossdomain.xml file on the Oracle BI Server, and now I am getting these Warnings/Errors :

Warning: Ignoring <site-control> tag in policy file from http://ddc3obi001:9704/analytics/crossdomain.xml.  This tag is only allowed in master policy files.

Warning: Domain ddc3obi001 does not specify a meta-policy.  Applying default meta-policy 'master-only'.  This configuration is deprecated.  See http://www.adobe.com/go/strict_policy_files to fix this problem.

Error: Ignoring policy file at http://ddc3obi001:9704/analytics/crossdomain.xml due to meta-policy 'master-only'.

The problem is that I haven't got a clue of how to implement a meta-policy files on OCJ4 containers.

I will install firebug to get more details on the errors.

Problem sorted.

We've managed to put the crossdomain.xml file in the right directory on the Oracle BI Server, which was not easy to find...
