8. Installing Struts2 in a web project Struts.xml is the file where struts is configured Copy the struts2 files into the folder: WEB-INF/lib

9. Creating the first struts2 application

10. Creating the first struts2 application Checking the web.xml < filter > < filter-name > struts2 </ filter-name > < filter-class > org.apache .struts2.dispatcher.FilterDispatcher </ filter-class > </ filter > < filter-mapping > < filter-name > struts2 </ filter-name > < url-pattern > /* </ url-pattern > </ filter-mapping >

11. Creating the first struts2 application Checking the file struts.xml Logical names Action clases JSPs < struts > < package name = &quot;app02a&quot; namespace = &quot;“ extends = &quot;struts-default&quot; > < action name = &quot; Product_input &quot; > < result > /jsp/Product.jsp </ result > </ action > < action name = &quot; Product_save” class = &quot; app02a.Product” > < result > /jsp/Details.jsp </ result > </ action > </ package > </ struts >

12. The file product.jsp <%@ taglib prefix = &quot;s&quot; uri = &quot;/struts-tags&quot; %> < html > < head > < title > Add Product Form </ title > < style type = &quot;text/css&quot; > @import url(css/main.css) ; </ style > </ head > < body > < div id = &quot;global&quot; > < h3 > Add a product </ h3 > < s:form action = &quot;Product_save&quot; > < s:textfield label = &quot;Product Name&quot; key = &quot;productName&quot; /> < s:textfield label = &quot;Description&quot; key = &quot;description&quot; /> <s:textfield label = &quot;Price&quot; key = &quot;price&quot; /> < s:submit /> </ s:form > </ div > </ body > </ html > Properties of the action class

13. The file details.jsp <%@ taglib prefix = &quot;s&quot; uri = &quot;/struts-tags&quot; %> < html > < head > < title > Save Product </ title > < style type = &quot;text/css&quot; > @imp o rt url(css/main.c s s); </ style > </ head > < body > < div id = &quot;global&quot; > < h4 > The product has been saved. </ h4 > < p > < h5 > Details: </ h5 > Product Name: < s:property value = &quot;productName&quot; />< br /> Description: < s:property value = &quot;description&quot; />< br /> Price: $ < s:property value = &quot;price&quot; /> </ p > </ div > </ body > </ html > Properties of the action class

14. The action class public class Product implements Serializable { private String productName ; private String description ; private String price ; ... public String execute () { return &quot;success&quot; ; } }
