I just started with .net. I used IBatis in Java without any issues.
My architechture is similar to Netpetshop application except that I dont have Presentation layer separated. I have included Presentation in the Web.
So, All the config files are in the web project's root. I am getting below error when trying to authenticate a user against SQL database. Anyone please suggest possible cause. Error is thrown while executing this code in Service Layer:
ConfigureHandler handler =
new ConfigureHandler( ServiceConfig.Reset );try
{
DaoManager.ConfigureAndWatch( handler ); // Here is where error is thrown
}
catch(Exception e){
Console.WriteLine(e.Message);
}
Error:
{"DaoManager could not configure DaoFactory. The DAO named \"User\" not found, failed. Cause: Object reference not set to an instance of an object." }
