This module explores foundational web technologies used in enterprise-level Java applications, focusing on the server-side processing and data communication layers. Learners are introduced to Java Servlets for dynamic content handling and to middleware concepts, particularly the role of Enterprise JavaBeans (EJB) in distributed systems. The second half of the module deepens understanding of XML, its role in SOAP-based web services, and the critical components and structures that ensure effective communication between systems. Through these lessons, learners build a strong base in how modern Java-based applications manage data and business logic across web platforms.

This module provides a comprehensive introduction to the foundational elements of web development. Learners explore how web technologies work, starting with the basic client-server model and moving into key web design principles used in creating user-centered websites. The module also covers the structure and syntax of HTML, emphasizing practical implementation techniques such as inserting images, designing layouts, and embedding content using frames. By the end of this module, learners will have a clear understanding of how to structure and present web content effectively using HTML and best practices in web design.

This module introduces learners to the foundational concepts and techniques of Cascading Style Sheets (CSS) for styling web pages. It begins with the importance of CSS in modern web development and explores how CSS enables consistent and efficient control over the presentation layer. Learners will understand essential rules and structures for applying styles, including the use of selectors, declarations, and positioning. The module also covers core concepts such as the CSS Box Model and relative layout adjustments, culminating in practical applications like subscript rendering and design precision. By the end of this module, learners will be able to apply CSS to enhance the visual structure, consistency, and responsiveness of web interfaces.

This module introduces learners to the dynamic aspects of modern web development by integrating client-side scripting and asynchronous communication. It begins with the principles of AJAX and the use of JavaScript and jQuery to communicate with web servers without reloading pages. The module also covers how to construct and handle XMLHttpRequests, explore source code interactions, and implement responsive web behavior. In the second half, learners will explore JavaScript fundamentals and how XML is used to structure and exchange data between systems. Through real examples and practical use cases, learners will gain the skills to build interactive, data-driven web applications.

This module explores advanced uses of XML in enterprise and web development environments. Learners will begin by examining practical XML applications such as RDF, metadata description, and domain-specific uses. The module then transitions into working with XML in Java frameworks like Hibernate and includes key topics like XML parsers, CDATA sections, and structural rules for well-formed XML. Finally, it covers integration with web services, focusing on SOAP messaging, WSDL specifications, and service discovery using UDDI. By the end of this module, learners will have the tools to apply XML in real-world integration scenarios, especially in Java-based and service-oriented architectures.
