Help with beginning Java web programming?

I'm interested in beginning Java web programming but I'm unsure as to
where to start and what I have read has only managed to confuse me.

First:
What should I learn if I want to develop a Java web application?

Second:
I've heard many names thrown around and need some help making sense
of it all. What is/are Jakarta, Struts, Tomcat, EJB/Hibernate, Ant,
JSP, Servelets and how do they relate to each other?

Third:
I've heard that JSP is for seperating presentation and application
logic, how do I process the form a user sends in? A 'Checkout' button
on a shopping cart would be a good example. Do I use JSP, a servelet,
other?

i suggest to begin with book "Head First Java". It is perfect for newbies.

> First:

Servlets.  JSP's translate to servlets at runtime.


Open Source projects

Model View Controller implementation to seperate logic, data, presentation; 
under an open source project....

Open source web server that includes java support

Enterprise Java Beans.  Middleware for java.  Design by contract by 
fulfilling the specification of EJB you wish to implement

Middleware approach different (understand to be easier than) EJB.
** Note: you must understand the concepts of a transaction to properly apply 
design and implement the above two acronymns

Another Tool for Make files, but greatly expanded with tasks for doing just 
about everything to build large/small application with a script

Java Server Pages which compile to servlets

Java which compiles at runtime and outputs HTML to the HTTP server port

In what you build surely available in volumes, volumes, and more volumes of 
internet and printed publication :-}

Learn Struts methodology!!

Good luck!
