nTier’s Patterns in Frameworks course is a three-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 course is delivered in a 70 percent 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 refactor 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 recurring problems.
This course can be customized to focus on a particular framework of your choosing.
Course Duration: 3 days
Course Objectives:
- Enable students to learn the frameworks more quickly
- Equip students to leverage common frameworks and the JEE environment to their fullest extent
- Understand and practice refactoring
- Ground students in key patterns that they can reuse
