Web 2.0 Applications using Java Servlets, JSP, and Ajax Training Course in the UK

JAWeb101 Building Web 2.0 Applications using Java Servlets, JSP and Ajax
Next Course Dates Call for schedule
Duration 3 days


Attending students should be able to use the syntax of the Java language without difficulty. Familiarity with the behavior of accessing web content from the perspective of the end user is also helpful.

Who Should Attend? Designed for developers who wish to create state-of-the-art Web 2.0 applications using Java EE technologies.
Course Benefits

Building Web 2.0 Applications using Java Servlets, JSP and Ajax provides all the information required to build state-of-the-art Web 2.0 applications using Java EE technologies such as Servlets and JSP. Java Servlets allow flexible handling of user requests without the limitations of CGI-based applications or those created in a web server-specific manner. The JavaServer Pages technology allows one to create sophisticated dynamic web content while harnessing the power of Java and Java Servlets. Ajax will allow your web sites to be even more dynamic and responsive to user request.

You Will Learn How To

Lesson objectives help students become comfortable with the course, and also provide a means to evaluate learning. Java Servlets and JavaServer Pages are essential server-side Java technologies for building web applications. Servlets are programs that run on a web server; they can respond to client requests. JavaServer Pages are useful for dividing work between Java developers and HTML designers. Ajax allows a web page to be very dynamic and responsive to the user's actions. This course is a comprehensive tutorial in the design and programming of servlets and JSPs. Students will learn about:

  • Building scalable web applications
  • Servlets and JSP technologies
  • Custom tag development
  • Web application design and architecture (using Model 2)
  • Various Web Application techniques
  • Web Security
  • Ajax (from scratch)
  • Introduction to Ajax toolkits and frameworks (e.g, Dojo)
  • Explore DWR

A correct architecture and design is paramount. That's why we explain all technologies within the Model 2 architecture (de de-facto standard, which is also followed by frameworks like Struts, JSF and Spring MVC). So we will not explain Servlets and JSP as a list of technologies as they where specified chronically, but always within its architectural context. You will learn all technologies.
