wcf - Cross Domain XMLHTTP ERROR

Hi HanneSThEGreaT,

I saw your code and config file, it looked was right. But, in my opinion,

we should make sure your service is worked fine. We can use fiddler to debug it.

Debug WCF REST Service.

If it worked fine. That means the client issue, as far as I know, when we call a wcf service form moble

phone, we need to setHeader, like below:

request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");

Next, may be you can try add this section in your web.config file. Like this

 <standardEndpoints>
    <webScriptEndpoint>
      <standardEndpoint crossDomainScriptAccessEnabled="true"></standardEndpoint>
    </webScriptEndpoint>
  </standardEndpoints>

This node should be add as a child node of servicemodel.

For more information, please refer to the following articles:
