not able to access dynamic map service

Hey

This might be a simple stuck but i am not able to resolve it. I have published a simple map service and is trying to access the map service through silverlight application. I am working on visual studio 2008 sp1 with silver light api 1.2 and silvelight kit installed.\

I haev also added clientaccesspolicy.xml and crossdomain xxml file to wwwroot directory.

here is the piece of my code:
<UserControl x:Class="SilverlightApplication1.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:theme=
"clr-namespace:System.Windows.Controls.Theming;assembly=System.Windows.Controls.Theming.BureauBlue"
xmlns:esri="clr-namespace:ESRI.ArcGIS.Client;assembly=ESRI.ArcGIS.Client"
xmlns:esriSymbols="clr-namespace:ESRI.ArcGIS.Client.Symbols;assembly=ESRI.ArcGIS.Client"
xmlns:esriConverters="clr-namespace:ESRI.ArcGIS.Client.ValueConverters;assembly=ESRI.ArcGIS.Client"
xmlns:esriToolkit="clr-namespace:ESRI.ArcGIS.Client.Toolkit;assembly=ESRI.ArcGIS.Client.Toolkit"

    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">

<Grid x:Name="LayoutRoot">
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="400"/>
        </Grid.RowDefinitions>



            <esri:Map x:Name="MyMap">
            <esri:Map.Layers>
                <esri:ArcGISDynamicMapServiceLayer ID=" map1" Url="https://localhost/ArcGIS/rest/services/forS/MapServer" />
                

            </esri:Map.Layers>
        </esri:Map>

    </Grid>
</UserControl>

If I try to access online layer, it works fine. but it does access the service hosted in my machine.

It throws the error : "A security exception occured while trying to access REST Endpoint".

Please help.

Thanks

Dear Domonique

Thanks for helping me out.

I am not able to access the service even if i put http://..... url.

I have placed both the xmls in the wwwroot directory.

Check that:
- your 'ClientAccessPolicy.xml' file is on the root of your services Web server (i.e. not your web application server if not the same).
- this file contains this line: domain uri="http://*"

If this is not working, try using fiddler to look at the requests sent to the servers. This might give a clue.

Dear Dominique

What is meant by root of Services web server? The Service is using IIS as the web server.

yes, the xml does have that line.

Thanks

By 'root', I meant that you should get your policy file by a request like : https://localhost/ClientAccessPolicy.xml
(by supposing 'localhost' is still your map server).

Are you able to access the REST endpoint from your web browser? This blog post might help: http://blogs.esri.com/Dev/blogs/silverlightwpf/archive/2009/08/24/Troubleshooting-blank-layers.aspx
