Patterns In Frameworks Workshop

Overview

nTier's Patterns In Frameworks course is a 3 day intensive workshop focused on the design patterns found in many common frameworks such as Spring, Struts and Java Server Faces (JSF). Common usage in JEE/J2EE is also included such as the servlet framework and EJB (2 and 3).

The intent of the course is two fold:

• Enable students to learn the frameworks quickly

• Equip students to leverage common frameworks and the JEE environment to their fullest extent

The course is delivered in a 70% hands on coding with minimal lecture. Lessons are delivered in a "Socratic" fashion whereby:

• Students are given a problem and asked to solve it

• A short lecture / demo is given in order to show our solution

• Students are given time to revise their solution as needed

Our goal is to provide a "real life" experience in which the participants code a single problem domain throughout the class and use the patterns in context to solve common reocurring problems.

This course can be customized to focus on a particular framework of your choosing.
