My map doesn't display

Hi, I'm wondering if anyone of you guys ever had this problem

I'm trying to display a DynamicMapServiceLayer but the map it doesn't show , I tried on IE8 and gives me an error about security and crossdomain and FF 3.5 just gives a [!] I've been looking how to solve this error but all I've found is "put de crossdomain.xml file into your web site directory" and I do it and still doesn't work 😞

Please help me!! if you have detail instructions I will apreciate very much

this is my code if it helps

Hello-

Try putting the crossdomainpolicy.xml at every root in your C:\Inetpub.

Ex:

Have it under the Inetpub, the folder in which you have the project, the ArcGIS Folder, etc.

I put this file in every location until it worked. Not very scientific but I've never had any trouble since doing so.

Also this portion of your code:



is commented out with the <!-- designation.

Thank you for your response, I will do it and tell you about it

That line is commented because that's the line I use to call my map service the one who doesn't work, that's why I try ESRI's public services but with its services I have no problem at all...
