Are you looking to dive into the robust world of enterprise Java for web development? The “Building Web Applications using Java EE” course on Udemy is an excellent starting point, offering a thorough exploration of essential technologies that power many modern web applications.
This course lives up to its name by guiding you through the entire lifecycle of building a web application. From the foundational setup of your development environment – including installing MySQL and the Eclipse IDE for Java Enterprise Developers – to the final deployment on a Tomcat server, every step is meticulously explained. This hands-on approach ensures you’re not just learning theory, but actively building a functional application.
The curriculum is impressively comprehensive. It begins with JDBC (Java Database Connectivity), covering everything from establishing connections to MySQL using various drivers, to mastering Statements, PreparedStatements, and ResultSets. The detailed explanations on scrollable and updatable ResultSets, along with CallableStatements for stored procedures, provide a deep understanding of database interaction. Transaction management and batch updates are also covered, which are crucial for robust application development.
Moving beyond the database, the course delves into Java Servlets. You’ll learn about the fundamental structure of web applications, how to create and invoke Servlets, and the intricacies of HTTP methods like doGet() and doPost(). The Servlet lifecycle, init parameters, file uploading, listeners, and filters are all explored, equipping you with the knowledge to handle complex web requests and application behavior.
JavaServer Pages (JSP) are then introduced, showcasing how to embed dynamic content within HTML. The course covers JSP structure, using code and forms, implicit objects, JavaBeans, database access directly from JSP, and the power of Expression Language. Crucially, it also details how to manage user sessions and navigation through cookies, HTTP sessions, and redirection.
The integration of JSTL (JavaServer Pages Tag Library) is a significant plus, simplifying JSP development by providing a set of standard tags for common tasks, including core, SQL, and XML operations. This streamlines code and improves readability.
Finally, the course tackles AJAX and jQuery, modernizing your web applications. You’ll understand how AJAX enables asynchronous communication, learn to use the XMLHttpRequest object, and see how to send and process JSON data using libraries like Gson. The inclusion of jQuery introduces efficient DOM manipulation and AJAX request handling, making your web interfaces more dynamic and responsive.
Overall, “Building Web Applications using Java EE” is a highly recommended course for anyone serious about mastering Java-based web development. Its step-by-step approach, comprehensive coverage of key technologies, and practical examples make it an invaluable resource for both beginners and those looking to solidify their Java EE skills.
