Request not sending from ios simulator to webserver

hello Sir,
I am using phonegap for ios app. it is working nice
in phoneGap Build. But when i open it in xcode, it is unable to send
request to server. I am using servlet to send request and response. I
have also used response.addHeader(“Access-Control-Allow-Origin”, “*”);. I
have upload a sample project to github:https://github.com/enamul95/TestMac.git
Please see my project .I have used it ionic framework. When i send
request , it shows from xcode simulator after adding ios platform
:Transport security has blocked a cleartext HTTP (http://)
resource load since it is insecure. Temporary exceptions can be
configured via your app’s Info.plist file. I have used access origing * in config.xml.

Please suggest me…
