For this the best place to start will be understanding JSR 168 which is the specification for Portlet. In very short I can tell you that a Portlet and Servlet follow the same life cycle.

To get a good understanding refer to following : http://createportlet.blogspot.com/2009/09/introducing-portal-world.html

Hi Leonardo,

A quick Google search of servlet vs. portlet will yield a lot of very good explanations.

Cameron's post does a great job explaining why you'd use a portlet over a servlet:

I also think this post by Chris from Unicon is a great starting point for developing portlets if you have a background in developing servlets.
