This video shows an example of Servlet, JSP, JDBC and Maven
In this we will use Eclipse, MySQL.
This video we will see :
- Creating Maven webapp project
- Adding dependencies
- pom.xml file
- Adding mysql-connector dependency
- What is MVC
- Connnecting project with tomcat
- Creating controller
- web.xml file
- Creating model class
- Creating JDBC connectivity
- Creating DAO layer
