The course Jakarta EE Web Development covers how servlets and JSPs are constructed and used in Jakarta EE Web Applications.
First the main methods of servlets are on the agenda, like the ones used in servlet initialization, reading HTTP request data and writing HTTP response data.
The different scopes of Web Applications such as session scope and application scope are explained. Next the basic syntax of JSP's scriptlets, expressions and declarations are covered and the different JSP page directives are treated.
A central element in the course is the MVC design pattern for Java Web Applications where servlets act as controller for program logic and JSP's as view for output data. In discussing this pattern, the RequestDispatcher interface is treated as well as the ways attributes can be stored and retrieved in different scopes.
Ample attention is paid to techniques to separate Java code from the JSP view. In particular the use of Java beans and custom tags for this purpose is discussed.
Also the role of deployment descriptors is part of the subject matter and security in Web applications, filters and the event framework are addressed.
The course Jakarta EE Web Development is intended for developers who want to build Java Web applications with Jakarta EE components like Servlets, JSP's custom tags, filter and event listeners.
To participate in this course experience with Java programming and object orientation is required.
The theory is treated on the basis of presentation slides and is interspersed with exercises. Demos are used to clarify the theory. All topics asked at the Java Web Component Developer Exam are discussed. The course material is in English.
Participants receive an official certificate Jakarta EE Web Development after successful completion of the course.
