Jakarta EE 9 Web Profile Fundamentals
by Kevin Jones
Jakarta EE 9: Web Profile is one of the most popular server-side frameworks in use today. This course will teach you the fundamentals of developing web apps using Servlets,JSPs and other parts of the Jakarta Web Profile.
What you'll learn
In this course we will learn to write server side web applications in Java. Jakarta Web Profile 9.0 is the latest in a long line of JEE (preveiously J2EE) specifications that cover server side, or enterprise, Java developemnt. This course covers thw Jakarta Web Profile, and that web profile specifies how Servlets, Jakarta Server Pages (JSP) and other Java web technologies work. Why are these fundamentals important? Well, because they underpin many of the Java web frameworks that exist today such as Spring MVC. For this course you will write an MVC style application which will use a Servlet as it's main controller, that means you will understand how to write and deploy servlets and. We will show how to use JSPs as the view technology withing this framework, and use the 'expression language' and 'tag libraries' to make these pages dynamic.You will learn how to use sessions to manage users and cookies to maange persistent user related state. On top of this you will understand how to use serlvet filters and events to track and respond to incoming HTTP requests and to transform the data in those requests and responses. You will also see how to write asynchronous servlets to help with scalability on the server side
About the author
A long time ago in a university far, far away Kevin fell in love with programming. Initially on the university's DEC20 computer doing BASIC and Pascal and a little bit of Fortran. His first job had him writing batch PL/1 on an IBM mainframe where he also discovered the arcane delights of JCL. He soon realized the multiuser systems were not for him after discovering the delights of dBase IV on IBM PCs. From here it was all downhill as he became addicted to C and the Windows API. Just missing out ... moreon coding for Windows 1, he did code for the other 16 bit versions of Windows, 2 and 3, including the various network-ready versions. He still remembers the awkwardness of having to carry an IBM Token Ring MAU with him wherever he went.
After trying to pretend that Windows and C were really object oriented he decided that it would be better to learn C++. It was around this point that he realized that as well as writing code for a living he could be paid for telling people how to write code for a living. He taught Windows, MFC and C++ for a UK training company before his spirit was broken on the back of the OLE support in MFC when he finally stepped away from the nightmare of unmanaged code to the nirvana of the managed runtime called Java.
It was at this time that he spoke at several JavaOne conferences usually on the subject of Servlets, JavaServer Pages and tag libraries. After buying the Sun employees copious amounts of Apple Martini Kevin was invited onto the expert groups for the Servlet and JSP specifications.
Oh, how he laughed when .Net appeared and the same arguments raged about non-deterministic destruction and garbage collection that were now so old hat in the Java world. He finally got his hands dirty in C# and .Net about eight years ago, again working in the web tier and hating every minute of the using the monstrosity that was and is ASP.Net Web Forms. It wasn't until MVC appeared that he finally felt he had come home to Microsoft.
Now of course MVC is so last year and Kevin is focusing more and more on rich clients using JavaScript and tools such as Knockout and AngularJS. He believes that JavaScript is the best thing since, well, JavaScript.
He still retains his passion for developing and teaching; spending about a quarter of the year doing the latter and most of the time doing the former.
When not stuck in front of a computer you can find him: with his nose in a book, a good one preferably, but almost any book would do; watching a film; walking; running; or annoying his wife by watching sports on television.
