Sandbox security violation error on compiling FDS

[Former Community Member]

Hi,

I am trying to compile am mxml using Remote Object locally
using Flex SDK outside FlexBuilder.

I have used the command:

mxmlc -services="path\to\my\services-config.xml"
-context-root=\ContextRoot FileName.mxml



I am getting the following error when I try to run the swf
generated:



[RPC Fault faultString="Send failed"
faultCode="Client.Error.MessageSend"
faultDetail="Channel.Security.Error error Error #2048: Security
sandbox violation:
http://localhost:9080/iReports/flexFiles/mxml/AdminServices.swf
cannot load data from
http://localhost:9080iReports/messagebroker/amf."

Can anybody help me?

Hi Cheree,

I struggled with a similar problem and I believe the first
thing you should try is to setup a cross-domain policy.

I found this in the Adobe Flex2 - Training from the Source
book and it says that you need a file called "
crossdomain.xml" inside the root of your webserver - where
the Flex app is running.



The file needs to look like this:

<cross-domain-policy>

<allow-access-from domain="*"/>

</cross-domain-policy>



Again, I assume you can also restrict access to specific
domains by putting some IP's in the specific tag, but I would start
with this *.



Somehow I feel that will resolve your problem, as it is
usually these security sandbox problems that appear with
cross-domain access issues.



regards and good luck,

Hi Sven,

Thank u so much for replying.

I ll definitely keep in mind what u told.

But my current issue is solved. The problem was:



[RPC Fault faultString="Send failed"
faultCode="Client.Error.MessageSend"
faultDetail="Channel.Security.Error error Error #2048: Security
sandbox violation:
http://localhost:9080/iReports/flexFiles/mxml/AdminServices.swf
cannot load data from
http://localhost:9080iReports/messagebroker/amf."



If u observe in the error message, the server was trying to
load '9080iReports', not '9080/iReports'. This is because I was
giving -context-root=\ContextRoot instead of
-context-root=/ContextRoot.

So, a silly mistake of using a back slash instead of forward
slash.



Thanks again,

Cheree
