Java Web Development

Complete Java Web Development

Complete Java Web Development is a crash course in developing cutting edge Web applications using the latest Java EE 5 technologies from Sun and the open source community. The course builds a strong understanding of Servlet technology as the cornerstone of Java’,s Web platform. It shows how JSPs build on the Servlet architecture and help your development teams achieve clear role separation. Allowing Web developers to focus on functionality while the Web designers create the layout - without stepping on each other’,s toes. Additionally, the class will show you how to use JSTL, custom tags and JSP expression language to reduce Java code in Web pages while adding tremendous power and capability to those pages. Attendees will also learn JavaBean component development and how these components can be easily integrated into JSPs. The class culminates in an exploration of Java MVC frameworks and compares some of the more popular offerings like Struts and Spring MVC.

While focusing on Web technologies, the course also exposes developers to the constant trade off between application robustness and complexity. This is not a class that focuses on theory. Participants will find the course is loaded with practical labs and simulations. After taking this class, your developers will be able to build Web applications faster, that are more scalable, and that are easier to maintain.

As the connected world becomes more integrated, companies are attempting to extend the reach of their applications to encompass clients directly. Java is an ideal tool to provide this reach.
This course covers the use of Java applets, JavaBeans, servlets and Java Server Pages to create web-based solutions that can deliver powerful, real-world applications power over an intranet, extranet or the Internet. It will cover key issues such as design, security, where XML fits, and the pros and cons of using distributed object protocols like RMI and CORBA in this type of application.
The course also introduces JDBC, and shows how it can be used in servlets and JSP to create, query, and update data in a relational database.

The practical sessions, which form more than half the course, build on the information given in the lectures. This will help delegates to reinforce their learning of Web development techniques and design options in Java.

Development with Java 2 Enterprise Edition
Enterprise JavaBeans Workshop
Java and XML Development Workshop

You Will Learn How To

Build scalable enterprise Web applications with Struts 2
Streamline the development cycle and apply best practices for testing Web applications
Detect and report user input errors with the Struts 2 validation framework
Access data with OGNL and generate results with JSP and Freemarker
Write and configure Struts 2 interceptors to achieve modularity and sophisticated functionality
Exploit the Struts 2 Tag Library to seamlessly integrate Ajax functionality

Course Benefits
Struts 2 is an enhanced Java Web framework that allows developers to create flexible, maintainable and easily configured Web applications with reduced effort. In this course, you gain a thorough knowledge of the architecture of Struts 2 and the application development process. Through hands-on exercises, you learn to take advantage of the core components of the framework.

Prerequisites
This course is aimed at experienced Java programmers wishing to gain experience in developing Web based solutions using the latest Java technologies in Java 2 Enterprise Edition.
Delegates should have a good grounding in the Java language and its fundamental constructs, such as threads and exceptions. This could be a result of at least 6 months hands-on Java development or possibly less if preceded by appropriate training, such as one of our Java programming courses.
An awareness of web technology such as HTTP requests and responses, HTML, and scripting would also be beneficial.


Delegates will learn how to
Use Java servlets to add Java code to a Web page
Communicate between an applet and a servlet
Secure a Java web application using digital certificates and Secure Sockets Layer (SSL)
Integrate servlets with RMI, CORBA, and EJB
Create Web pages dynamically using Java Server Pages (JSP)
Integrate JSP and JavaBeans
Maintain state in Java web applications using cookies and sessions
Access company data using JDBC in servlets and JSP
Integrate Java and XML
Use and create JSP Tag Libraries
Use the JSP Standard Tag Library (JSTL)
Use the Jakarta Struts framework to create MVC applications
