6. Java Web Development * Note In this course only JSP & servlets will be discussed

7. Structure of a web project There are two kind of structures The structure of the web application in a server The structure of the IDE A web project have three main elements The JSPs files The java classes The Configuration file web.xml

8. Structure of a web project in the server

9. Structure of a web project in the server Anything web-related Directories JavaServer Pages (JSP) HTML Css files JavaScript Files Etc. Java Libraries (.jar) Java classes (.class) Configuration files Root of the project

10. Introduction to Web Applications In a Web Application, web components provide the dynamic extension capabilities for a web server. Web components can be Java servlets, JSP pages, or web service endpoints. The interaction between a web client and a web application is explained and illustrated in the next slide figure. The client sends an HTTP request to the web server. A web server that implements Java Servlet and JavaServer Pages technology converts the request into an HTTPServletRequest object. This object is delivered to a web component, which can interact with JavaBeans components or a database to generate dynamic content. The web component can then generate an HTTPServletResponse or it can pass the request to another web component. Eventually a web component generates a HTTPServletResponse object. The web server converts this object to an HTTP response and returns it to the client.

11. Introduction to Web Applications

12. Introduction to Web Applications Servlets are Java programming language classes that dynamically process requests and construct responses. JSP pages are text-based documents that execute as servlets but allow a more natural approach to creating static content. Although servlets and JSP pages can be used interchangeably, each has its own strengths. Servlets are best suited for service-oriented applications (web service endpoints are implemented as servlets) and the control functions of a presentation-oriented application, such as dispatching requests and handling nontextual data. JSP pages are more appropriate for generating text-based markup such as HTML, Scalable Vector Graphics (SVG), Wireless Markup Language (WML), and XML.

13. Servlets versus JSP

14. Life Cycle of a JEE Web Application

15. Life Cycle of a JEE Web Application

16. Criteria to develop web applications

17. Exercise 1 Develope the first java web application Download the file: jspservlet-00.zip Unzip it Import from Eclipse Run it

18. Exercise 1 Results You should get this result

19. Exercise 1 Analisis The web.xml file <? xml version = &quot;1.0&quot; encoding = &quot;UTF-8&quot; ?> < web-app xmlns:xsi = &quot;http://www.w3.org/2001/XMLSchema-instance&quot; . . . version = &quot;2.5&quot; > < servlet > < display-name > HelloWorldServlet </ display-name > < servlet-name > HelloWorldServlet </ servlet-name > < servlet-class > com.example.servlets.HelloWorldServlet </ servlet-class > </ servlet > < servlet > < display-name > AnotherServlet </ display-name > < servlet-name > AnotherServlet </ servlet-name > < servlet-class > com.example.servlets.AnotherServlet </ servlet-class > </ servlet > Servlet declarations

20. Exercise 1 Analisis The web.xml file . . . < servlet-mapping > < servlet-name > HelloWorldServlet </ servlet-name > < url-pattern > /HelloWorldServlet </ url-pattern > </ servlet-mapping > < servlet-mapping > < servlet-name > AnotherServlet </ servlet-name > < url-pattern > /AnotherServlet </ url-pattern > </ servlet-mapping > < welcome-file-list > < welcome-file > index.html </ welcome-file > </ welcome-file-list > </ web-app > Servlet mappings

21. Exercise 1 Analisis Servlet classes (other might be here classes too) Other resources might be here
