error app

Question

Hej people-i am making simple Silverlight Application with WCF-my service is retrieving data from my Oracle to datagrid(i am using win 7,and domain mashine).

my WCF service looks like this:

using System;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;
using System.Data.OleDb;

namespace SilverlightApplication32.Web
{
[ServiceContract(Namespace = "")]
[SilverlightFaultBehavior]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1
{
[OperationContract]
public void DoWork()
{
// Add your operation implementation here
return;
}

[OperationContract]
public List<Employee> GetAllEmployees()
{
List<Employee> emps = new List<Employee>();
string connectionString = "connection string to Oracle";
OleDbConnection myOleDbConnection = new OleDbConnection(connectionString);
myOleDbConnection.Open();
OleDbCommand cmd = new OleDbCommand("select naziv,adresa from tabela12 ", myOleDbConnection);
OleDbDataReader reader = cmd.ExecuteReader();



while (reader.Read())
{
Employee emp = new Employee();

emp.name = reader.GetString(0);
try
{
emp.prezime = reader.GetString(1);
}
catch
{
emp.prezime = "Nema adrese";
}
emps.Add(emp);
}
return emps;

}

// Add more operations here and mark them with [OperationContract]
}
}



and my Employee class looks like :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace SilverlightApplication32.Web
{
public class Employee
{
public string name { get; set; }
public string prezime { get; set; }
}
}


my Web config look like this:

<?xml version="1.0"?>

Hi,

If the web service is being accessed from a different domain that the one from where your silverlight application is hosted, you will need  cross domain policy file.
