Testing & Documentation.

I think you are asking for punishment here. I am not sure from your question if you are already familiar with Java or not, but if you are just starting out, I wouldn't even plan on getting to 3/4 of what is in your list.

Web Java is a different beast than Java. You are going to spend a large amount of time getting things configured properly and running, even using advanced frameworks to do web development takes a good deal of time to setup properly (god forbid you have a tomcat misconfiguration somewhere).

I would also just drop the desktop application stuff (AWT/Swing). Unless you really have a need, don't bother. Focus on the web.

I would also recommend perhaps avoiding some of the frameworks until you understand the servlet lifecycle a bit. Same with the data access. I would never suggest anyone do this in a production environment, but try writing a small application that hits a database using standard J2EE jsp/servlet/jdbc technology.

After that, start incorporating a few of the frameworks in there. This will help you out when the framework doesn't work as expected and will also introduce you to the foundational technologies that all of the other libraries are built on.

I suggest you look at the http://java.sun.com/developer/releases/petstore/ example program. Give this is already written, I would allow a week to get it running and have a good idea what it does. You can spend as much as you want 1 day to 180 days changing it, or re-writing it.

I would also suggest you look for other sample programs which do things you might be interested in. You can learn a lot figuring things out for yourself, but it can be much faster if you have a working example to refer to.
