IntroductionCourse Outline

This course is delivered using the published book “Seam in Action”.  Each student will receive a copy of this book along with complementary lectures and labs developed by Web Age Solutions.

Topics
 
  • Seam Component Model
  • Testing Seam Applications
  • Seam and JSF
  • Error Handling and Debugging
  • Seam with EJB 3.0 and JPA
  • Stateful Seam Applications
  • Seam Application Enhancements
  • Seam and AJAX
  • Using Seam without EJB
  • Seam Production Deployment
What you will learn
  After completing this course, the student should be able to:
  • Describe and leverage the various advantages of the Seam programming model.
  • Use Seam in combination with various technologies like JSF, EJB 3.0, JPA, and AJAX.
  • Use various development tools to work more efficiently with Seam applications.
  • Test Seam applications.
  • Solve common application programming problems using Seam techniques.
  • Apply rule-based security to Seam applications.
  • Describe how to use Seam without EJBs and the tradeoff when doing so.
  • Deploy Seam applications into a variety of production environments.
Audience
 

This class is meant for Java Enterprise programmers looking to write a new breed of Enterprise applications based on Seam.
Prerequisites
 

Since Seam is designed to integrate with Java EE 5 technologies, students should have a good familiarity with Java and Java Enterprise programming.  For those new to Java Enterprise or perhaps with prior J2EE 1.4 experience the following course should be taken before WA1627.
