Java™ EE Web Application Development with Apache Struts 1

Duration: 5 days | Price: $2495 | Dates: 

Description:  This hands-on course provides participants with the knowledge and experience necessary to develop and deploy large, robust and complex Java web applications utilizing the Apache Struts 1 framework. The Apache Software Foundation has provided numerous open-source tools, which set the standard for web application development. These include the Apache web server and the Tomcat Servlet Container. Apache Struts 1 provides a flexible controller layer for JSP-based applications, with significant facilites for validation, internationalization and page layout. Struts is an implementation of the Model-View-Controller (MVC) pattern, a recommended architectural design pattern for interactive applications. The Struts controller is based on standardized technologies including Servlets, JSP Pages, Tag libraries, JavaBeans and XML. Students will learn how to use the Struts framework to write, assemble, configure and deploy complex web applications.

This course covers architectural design issues as well as specific coding models for Java EE components, and is up to date with the latest Java EE 5, JSP 2.1 and Servlet 2.5 specifications. Security, transaction management, inter-component communication and deployment issues are discussed in detail, with hands-on labs to solidify understanding. Since coding and deployment files are standardized by the Jave EE specifications, students may readily apply the skills learned in this class to write code for any compliant server, including Apache Tomcat, JBoss, WebSphere, Oracle, WebLogic and many others. Students will understand the role and architecture of the most important containers in the Java EE specification: the Web Container (which hosts HTML pages, Servlets and JSP Pages) and the EJB Container (which hosts Enterprise JavaBean components). Participants will learn how to use important Java EE services and protocols including JNDI, JDBC and JMS. Students will learn how to utilize ANT, a flexible and powerful XML-based build utility, to compile, deploy and execute stand-alone and enterprise Java applications. Comprehensive hands-on lab exercises reinforce instructor lectures and build direct competence in the topics presented throughout the course.

This course assumes that students possess a thorough knowledge of how to use Servlets, Java Server Pages, Tag Libraries, ANT and JDBC to exploit the services of the Java EE platform.

Prerequisites: Java SE 5 programming experience and an understanding of object-oriented design principles. Fundamental knowledge of XML and HTML is helpful but not required.
