Hi All,

I am trying to access the wcf JSON type service from remote server url from crome and safari browsers, but I am getting an error message. Following is the code

var jsonText2=JSON.stringify({"FirstName": "Avinash","LastName": "Patil"});

$.ajax({
            type:"POST",                     
            url:"http://192.168.2.56/AndroidWcfService/Service1.svc/UserRegistration",
            data:jsonText2,
            contentType:"application/json;charset=utf-8",
            dataType:"jsonp",        
            timeout: 1000*60*15,
            success:function(data )
            {
            	alert("inside success");
            	//alert(data.loginResponse+" ");
            	 
            	if(data)
            		{
            		//InsertDeviceInformation();
            		 alert("Success");       		
            	    }
            },
            error:function(error){
                alert("checkNWCon");
                }
            });

If I used the locally hosted service then it is working fine and giving the success results.

What are the changes need to call service from remote server!!!!
Please suggest ASAP.

Thanks for suggestions
