  • About Java

    Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture

    Java is general-purpose, concurrent, class-based, and object-oriented, and is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere". Java is considered by many as one of the most influential programming languages of the 20th century, and widely used from application software to web application.

Course Outline

This course enables the experienced Java developer to use the Spring Web Flow framework to create simple and complex web applications. Web Flow represents a powerful new approach to designing and developing web applications, and can also draw on the configuration capabilities of Spring itself. We begin with an introduction to the Spring Core module -- which implements the configurable object container available to Web Flow applications as an application context -- and get oriented to the Spring web framework, as underpinnings of the Web Flow system.

Then we dive into Web Flow itself, and develop key concepts of flow, state, transition, and action. We get moderately complex applications up and running with these elements, and see how the JavaBeans used to power a flow can also take advantage of Spring configuration and dependency injection. Then we move into more advanced techniques including custom converters, validators, and subflows. We conclude the course with a look at lifecycle and context features, such as the FlowExecutionListener.

  • Understand the scope, purpose, and architecture of Spring
  • Use Spring's bean factories and application contexts to declare application components, rather than hard-coding their states and lifecycles
  • Use dependency injection to further control object relationships from outside the Java code base
  • Use annotations to take advantage of Spring post-processors for automated bean instantiation and wiring
  • Create validators for business objects, and associate them for application-level and unit-testing uses
  • Build a simple Web Flow application, with declarative control over page flows.
  • Bind model beans to pages, and control when binding should and shouldn't occur.
  • Invoke Java methods as actions on controllers, service objects, and other JavaBeans placed in Web Flow or Spring singleton scopes.
  • Install custom data-binding logic.
  • Develop validation logic for individual model beans and view states.
  • Organize more complex applications into master flows and subflows.
  • Observe the progress of a flow using a flow execution listener, and implement interceptors over one or more lifecycle hooks.
  • Java programming
  • Basic knowledge of XML
  • Servlets programming
  • JSP
