I disagree with Jake that we all should learn Puakma to move/learn WAS or other J2EE technologies since puakma is very similar to Domino. I think while learning J2EE one should keep aside Domino style of design/development.J2EE is much complex than Domino but it will be easier to learn if you don't compare it with Domino.
Its my practicle experience...I am developing Domino App more than 6 years and Websphere Apps since last 2 years.
You can easily get 60 day trail copy of WAS and WSAD or you can start with Tomcat or JRun and MySQL.
