Learning Objectives

Students will leave the course armed with a full set of skills to design, implement, deploy, and troubleshoot Struts 2.0 web applications.   This course provides coverage of all the standard components, filters, renderers, converters, and validators, along with advice on how to use them to create solid applications.  Working in a hands-on environment  students will explore and use complex user interface layouts, prototyping, and integrating templates with back-end model objects. 

Working in a dynamic, interactive discussion and hands-on programming environment, developers will:

The course provides a solid foundation in basic terminology and concepts, extended and built upon throughout the engagement.   The course then builds on this solid foundation to provide a complete picture of effective Struts 2.0 application development. Processes and best practices are discussed and illustrated through both discussions and group activities.

Attending students will be led through a series of advanced topics comprised of integrated lectures, extensive hands-on lab exercises, group discussions and comprehensive demonstrations. Please see below for additional information about the hands-on lab work.
