Training Description

JSP and Servlet programmers learn how to build "Model-2" Web applications using the Jakarta Struts project from Apache. Students will learn how to implement best practices in web application development through the use of the Struts architecture.

Training Objectives

As a result of taking this training, students will be able to:

  • Develop and deploy applications to the Struts architecture.
  • Use the Struts and JSP tag libraries to declaratively create pages with minimal coding.
  • Perform internationalization (il8n) in Struts.
  • Perform efficient input validation in Struts.
  • Perform advanced configuration in Struts, such as role-based security and chained actions.

Prerequisites

  • Familiarity with Java programming, Servlets programming, JSP and JavaBeans; familiarity with Web page development (HTML and XML).
  • Minimum software requirements: Java Enterprise Edition Software Development Kit (Java EE SDK). JavaServer Faces (JSF) visual development environment, such as Eclipse, NetBeans or Sun Java Studio Creator. Apache Tomcat. Struts development framework (downloadable from struts.apache.org). Optional JDBC-compliant relational database, such as Oracle, MySQL or Microsoft SQL Server.
  • Minimum hardware requirements: Pentium at 1.5 GHz, 1 GB RAM; 5 GBfree hard disk space before installation. Internet access.
