Struts 2 Framework for Beginners

set up a tomcat 8 server by downloading tomcat 8 from the official website, adding the tomcat server to eclipse, and resolving port conflicts by changing 8080 to another port.

Explore the field validator tag in Struts 2, which enables XML-based validation by inheriting the field name and grouping validations like age as integer and email format.

Explore Struts2 tags by building a registration form with a text area for address and a reset tag. Bind the address to the action and display it on welcome page.

Populate an array list of colors in a Struts 2 action and load it via the form load action to display color options in the register page.

Learn to build a Struts 2 checkbox list for hobbies, programmatically populate a hobbies list in the action class, and display selected hobbies as a comma-separated string.

Learn how the Struts2 iterator tag iterates over a product list to render a table on the registration form, displaying product id, name, and price with property tags.

Use the if else tag in Struts 2 to conditionally display subscriber messages in welcome.jsp based on a subscription value.

Download Oracle 11g from the official Oracle site, run the installer, choose the install path, enter and remember the login password, and complete the Oracle database installation.

Explore how Jdbc, the Java Database Connectivity API, lets a Java application interact with any relational database using interfaces and classes, remaining independent of a specific RDBMS.

Explore the four JDBC driver types—type 1, type 2, type 3, and type 4—and how each converts JDBC calls to database specific protocols.

Explore JDBC classes and interfaces, including DriverManager, Connection, Statement, PreparedStatement, CallableStatement, ResultSet, ResultSetMetaData, and DatabaseMetaData.

discover the five JDBC connectivity steps: load and register the driver, create a connection with the DriverManager, create a statement, execute a query, and close the connection, using Oracle specifics.

Learn how to establish a connection to an Oracle database by loading the driver, using DriverManager.getConnection with a url, user, and password, and importing the Oracle driver jar in Eclipse.

Learn to connect to an Oracle database, execute a select query, and read and display results on the screen using a statement and a ResultSet.

Update an employee's salary using a JDBC update statement in the Struts 2 beginner course, showing single-row and multi-row updates with a where clause and the rows affected.

Use a prepared statement to delete from employee where employee ID is equal to a parameter, bind with setInt(1, 103), call executeUpdate, and verify the number of rows affected.

Learn to use a callable statement to execute a stored procedure that inserts an employee record, including creating the procedure, binding parameters, and validating the insertion.

Begin by building a product management application using struts2, implementing basic crud: login, view, add, update, and delete products; explore project structure, dao, db util, and pojo layers.

Set up a web project and configure web.xml and doctype, then implement a db util, login info POJO, login dao, and login action to validate credentials against login info table.

Configure a Struts 2 login flow, mapping success and input results, and build login and welcome JSPs with a centered form and basic styling.

Demonstrate the delete product flow in Struts 2, invoking the delete action via a link and query string, deleting the item from the database, and redirecting on success.

Explore running the Struts 2 application, highlighting built-in form validation for the product price, handling invalid input, and performing add, update, and delete actions.

Upgrade your Eclipse IDE to Photon, update Struts 2 to 2.5.20, and Tomcat to 9.0.16, then reconfigure workspace, Java build path, and deployment settings to run the updated project.

Explore internationalization and localization in software, and learn how i18n and l10n enable language, date, numeric, and cultural adaptations for a global user base, with Struts2 support.

Implement internationalization and localization in a Struts2 app by using resource bundles and locale-specific properties files, binding keys in JSP and following a global properties search order.

Learn how to implement internationalization and localization in Struts 2 by creating locale-specific properties files, adding language switch links, and using the url tag to pass the request_local parameter.

Explore the internal flow of Struts 2 interceptors by tracing how an action invocation orchestrates the interceptor stack, handles pre-processing and post-processing, and resolves results with validation checks.

Create a functional Struts 2 age group interceptor that reads the age from the value stack, assigns a group (children, adult, senior), and appends it to the age for display.
