JSP, Servlets and JDBC for Beginners: Build a Database App

Explore how jsp and servlets power dynamic web apps by generating html on the fly from user input and database results, and see how they fit into java ee architectures.

Set up your development environment by installing the JDK, Tomcat server, and the Eclipse IDE, then follow high-level steps across dedicated installation videos.

Install and verify Tomcat 9 on Windows for Java EE JSP/Servlet apps, using the binary Windows service installer, configuring as a service, and confirming via localhost:8080.

Install Tomcat 9 on Mac, download from tomcat.apache.org, unzip the tar.gz, start the server with startup.sh, and verify by visiting localhost:8080.

Download Eclipse for Java EE developers from eclipse.org, unzip it, and move the folder to your jsf-for-beginners directory. Launch Eclipse, create a new workspace, and verify the Java EE version.

Connect Eclipse to Tomcat by starting Tomcat from Eclipse and deploying web applications directly to Tomcat, using the servers tab to add and configure the Tomcat server.

Build a hello world program with JSP, an HTML page with Java code that generates dynamic content on the server and returns HTML to the browser.

Explore JSP expressions, scriptlets, and declarations, and see how to embed Java expressions in HTML using <%=%>, <% ... %>, and <%!...%>, with strings, math, and boolean examples.

Use JSP scriptlets to embed Java in a JSP page with angle-bracket percent syntax and out.print, demonstrating a for loop that prints content dynamically while minimizing scriptlet code.

Declare and call a jsp declaration inside a jsp page using the declaration syntax. See a simple makeItLower example that converts text to lower case and displays it.

Refactor the JSP by moving business logic to a separate Java class (FunUtils) and call it from the JSP, reducing scriptlets; run on the server to see lowercase output.

Explore JSP built-in server objects such as request, response, out, session, and application. Learn to use the request object to read headers and language for dynamic pages.

Use jsp:include to insert header and footer across pages by including my-header.html and my-footer.jsp, then assemble homepage.jsp with these includes and a dynamic timestamp.

Learn to build an HTML form for first and last names, submit to student-response.jsp, and read data with JSP using request.getParameter or ${param.firstName} and ${param.lastName} to display a confirmation.

Build and submit an html form in eclipse, sending first name and last name to student-response.jsp via form action. Display a confirmation with the entered names using param.firstName and param.lastName.

Learn to build and integrate HTML dropdown lists with forms using the select tag and country options, then process and display the selected country in a JSP page.

Build HTML forms with radio buttons, then process and display the selected language using JSP, including an example form, radio inputs named favoriteLanguage, and a JSP confirmation page.

Use HTML check boxes to let users select multiple programming languages and submit to a JSP page, using request.getParameterValues, then display the selections as a list on the confirmation page.

Explore building a checkbox form in Eclipse, creating student-checkbox-form.html and student-checkbox-response.jsp, and display selected languages by looping over request.getParameterValues in a JSP scriptlet.

Discover how JSP sessions track user actions with a per-user session object. See a to-do list demo, using setattribute and getattribute, and learn how Tomcat stores IDs in memory.

Explore session tracking in JSP by building a to-do list app that tracks user actions, stores items in the session, reads form data, and displays items from an ArrayList.

Personalize sites by setting and reading cookies that remember user preferences, like language or travel details. Use the javax.servlet.http.Cookie API in JSP to create, set max age, and read cookies.

Learn how to personalize a JSP app using cookies, with a three-page demo that sets and reads a favorite language to tailor books, news, and jobs.

Create a cookie-based personalization flow in JSP: build a language preference form, set a cookie, and render a customized homepage showing language-specific content.

Explore jsp tags, including custom tags and the standard tag library (jstl), and learn how they reduce scriptlet code, enhance reuse, and simplify presentation in jsp pages.

Install the JSP Standard Tag Library (JSTL) by downloading the JSTL jars, placing the implementation and API in web-inf/lib, and testing a JSP using the core tag library and EL.

Explore JSTL core tags, with emphasis on forEach looping using c:forEach, alongside if, choose, import, and out. Learn taglib setup and attributes in scope.

Explore JSTL core tags by looping with forEach in a JSP demo, creating sample city data, setting it as a page context attribute, and rendering Mumbai, Singapore, and Philadelphia.

Learn to render an HTML table from a list of Student objects using JSTL core forEach in JSP, displaying firstName, lastName, and goldCustomer status.

Learn how JSTL core tag if performs a conditional test in JSP, displaying content when temp student is a gold customer and condition evaluates to true, and hiding it otherwise.

Use the JSTL choose tag to implement switch-like conditional rendering with when and c:otherwise, deciding between a gold customer discount and a default message.

Explore JSTL function tags with fn:length, fn:toUpperCase, and fn:startsWith, learning how to compute string and collection lengths and perform basic string manipulation in JSP.

Explore JSTL function tags for splitting and joining strings in a JSP app, turning a comma-separated string into an array and joining an array back into a string.

Explore jstl internationalization in jsp, using i18n, locales like en_US and en_GB, and labels and message bundles for language-specific content, dates, numbers, and currency formatting.

Build a multi-lingual jsp app using JSTL internationalization tags; create locale-specific properties files and dynamic placeholders, and switch languages via user-selected locale.

Create locale resource files in a JSP project, starting with a default mylabels.properties and adding es and de locales. Copy and translate label.greeting, label.firstname, label.lastname, and label.welcome.

Create a JSP page in the web content directory using JSTL formatting tags to pull labels from resource files. Reference keys like label.greeting, label.firstname, and label.welcome to show i18n messages.

Update a jsp page to switch locale via top links (en_US, es_ES, de_DE) using JSTL i18n bundles to display translated data and show the selected locale.

Build a simple Java servlet that generates HTML on the fly, processes requests, and returns content with doGet and PrintWriter, while handling form data, cookies, and sessions.

Create a hello world servlet in Eclipse, set up a dynamic web project, and generate HTML with doGet, a print writer, and the response, then run on Tomcat.

Explore the differences between servlets and JSP, how they complement each other in the MVC pattern, and when to use each to build Java web apps.

Learn to read html form data with servlets by building a student form, submitting via GET to a servlet's doGet method, and retrieving parameters with request.getParameter.

Create an html form that submits to a servlet via get. Read firstName and lastName with request.getParameter and return a dynamic html confirmation from StudentServlet.

Compare get and post form methods in jsp and servlets, noting that get appends data to the url. Post sends data in the body and suits large or sensitive data.

Learn how to configure a Java web app with servlet context parameters in web.xml, and read them in a servlet using ServletContext.getInitParameter to display values like max-shopping-cart-size and project-team-name.

Configure servlet parameters in web.xml and read them in the doGet method with servletContext.getInitParameter. Generate HTML that displays max shopping cart size and the project team name coding gurus.

Explore the model-view-controller pattern with servlets and JSP, wiring the controller to a JSP view, passing data via request attributes, then render the list using JSTL.

Learn to build a simple mvc app by adding JSTL to a servlet project, creating an mvc demo servlet, and forwarding data to view_students.jsp with a JSP loop over student_list.

Deepen mvc with servlets and jsp by showing how the controller uses StudentDataUtil to fetch a student list and forward it to a table-based jsp view.

Create a student class in a new mvctwo package, define fields for firstName, lastName, and email, with a constructor and automated getters and setters using Eclipse tricks.

Create a StudentDataUtil helper to provide the servlet with a list of sample students by building an empty list, adding Mary Public, John Doe, Ajay Rao, and returning the list.

Create an MVC servlet named MvcDemoServletTwo, fetch students from StudentDataUtil, set them as request attribute 'student_list', and forward to view_students_two.jsp with the request and response.

Copy view_students.jsp to view_students_two.jsp, build an HTML table with first name, last name, and email, and loop over tempStudent data in MVC to display each student.
