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.

Create a database table using a jdbc statement in a Struts 2 beginner tutorial, detailing load driver, connect, create statement, and execute update to build an employee table.

Insert records into the employee table using insert into values, use single quotes for strings, omit fields by listing columns, and order by employee ID.

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.

Delete the employee with id 104 using a statement, verify one row affected, then remove all rows by omitting the where clause and confirm no rows remain.

Compare statement and prepared statement objects, showing how prepared statements use parameterized queries with binding, compile once, and reuse for efficiency with inserts, updates, and deletes.

Learn how to insert records into an employee table using a prepared statement, bind parameters with setInt and setString, and verify rows affected via execute update.

Update the employee table records using a prepared statement: bind salary and id with setInt, executeUpdate, and verify the affected row to confirm the change.

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.

Implement the welcome action to fetch all products from the database via the product management dao and bind them to the welcome page's tabular display.

After login, redirect to the welcome action to initialize the product list and render welcome.jsp that displays a table of products with update and delete actions.

Implement add product in Struts 2 by binding id, name, category, and price, calling the DAO method, and redirecting to the welcome action on success or error.jsp on error.

Demonstrates updating a product in Struts 2 by pre-populating the update form and executing the update action. Redirects to the welcome action to refresh the list.

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 how an interceptor stack defines the execution order of Struts interceptors and how the default and custom stacks influence parameter loading on the value stack.

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.

Explore how the custom age group interceptor works within a Struts 2 app, examining interceptor order, value stack data flow, and debugging steps to confirm pre- and post-processing.
