Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException:

owais ul haq — Thu, 18 Jan 2024 07:34:04 +0000

I am using NetBeans IDE. I am learning Spring Framework and I am facing an error that "bean named 'student' is not available", although I have used given a name to my bean in config.xml.

Below is the error I am getting:
"Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'student' available"

Below is the file structure of my project,

Below is my code. Kindly take a look at it and let me know where I am making a mistake.
