The purpose of this white paper is to evaluate the comparative efforts (based on IT development and support time) that are required to build a portal using WebSphere Portal software or to develop that same portal using a custom Java 2 Platform, Enterprise Edition (J2EE) technology-based framework approach. To create a portal, one must build its portlets while considering two other layers of functionality: the foundation layer holding services, and an administration interface that can maintain the portlets in addition to the overall look and feel and security of the portal. This white paper examines each of the three functional areas and the different approaches one can use to build them.
