24.     <artifactId>tomcat-jasper</artifactId>  
25.     <version>9.0.12</version>

2. Create the bean class

Reservation.java

1. package com.javatpoint;  
2.   
3. public class Reservation {  
4.   
5.     private String firstName;  
6.     private String lastName;  
7.     private String Gender;  
8.       
9.     public Reservation()  
10.     {         
11.     }  
12.     public String getFirstName() {  
13.         return firstName;  
14.     }  
15.     public void setFirstName(String firstName) {  
16.         this.firstName = firstName;  
17.     }  
18.     public String getLastName() {  
19.         return lastName;  
20.     }  
21.     public void setLastName(String lastName) {  
22.         this.lastName = lastName;  
23.     }  
24.     public String getGender() {  
25.         return Gender;  
26.     }  
27.     public void setGender(String gender) {  
28.         Gender = gender;  
29.     }     
30. }  

3. Create the controller class

ReservationController.java

1. package com.javatpoint;  
2. import org.springframework.stereotype.Controller;  
3. import org.springframework.ui.Model;  
4. import org.springframework.web.bind.annotation.ModelAttribute;  
5. import org.springframework.web.bind.annotation.RequestMapping;  
6.   
7. @RequestMapping("/reservation")  
8. @Controller  
9. public class ReservationController {  
10.     @RequestMapping("/bookingForm")  
11. public String bookingForm(Model model)  
12. {  
13.       //create a reservation object   
14.     Reservation res=new Reservation();  
15.       //provide reservation object to the model   
16.     model.addAttribute("reservation", res);  
17.     return "reservation-page";  
18. }  
19. @RequestMapping("/submitForm")  
20. public String submitForm(@ModelAttribute("reservation") Reservation res)  
21. {  
22.     return "confirmation-form";  
23. }  
24. }  

4. Provide the entry of controller in the web.xml file

web.xml

2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">  
3.   <display-name>SpringMVC</display-name>  
4.    <servlet>    
5.     <servlet-name>spring</servlet-name>    
6.     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    
7.     <load-on-startup>1</load-on-startup>      
8. </servlet>    
9. <servlet-mapping>    
10.     <servlet-name>spring</servlet-name>    
11.     <url-pattern>/</url-pattern>
