Course Objectives

This five day training class teaches students WebSphere Portal development using JSR 286 portlet API. The JSR 286 API is a major revision of the portlet specification and contains significant improvements. The class also covers JavaServer Faces based portal site development and using Dojo and AJAX with portlets. All labs are carried out using Rational Application Developer (RAD) 8.5.

The following topics are covered in this course:

  • Introduction to WebSphere Portal, key concepts and benefits
  • Portal programming model
  • Detail coverage of the JSR 286 API
  • Introduction to Portal Toolkit
  • Struts based portlet development
  • JavaServer Faces (JSF) based portlet development
  • AJAX
  • Using Dojo in portlets on WebSphere Portal
  • Web Services for Remote Portlets


At the end of this course, delegates will be able to:

  • Install and use the latest Portal Toolkit
  • Understand the JSR 286 portlet programming model
  • Use the Rational Application Developer (RAD) 8.5 based Portal Toolkit to build portal applications
  • Develop cooperative portlets to share data
  • Develop portlets using Struts and JavaServer Faces (JSF)
  • Use AJAX in a portlet
  • Provide and consume portlets using Web Services for Remote Portlets (WSRP)
