Building Java / JEE Web Applications with Servlets, JDBC, JNDI and More

Learn Core Java Web & JEE Development Skills to Build Robust, Scalable, Production Quality Web Applications

Course Code: TT6262

Skill Level: Introductory

Duration: 5 Days

Course Overview

Servlets and JavaServer Pages (JSPs) are key server-side Java technologies for building web applications. Servlets are programs that run on a web server; they can respond to client requests and create dynamic content. Java Servlets allow flexible generation of dynamic content without the limitations of CGI-based applications or those created in a web server-specific manner. The JavaServer Pages (JSP) technology allows one to separate static from dynamic content while harnessing the power of Java Servlets.

Struts 2 is an open source, Model-View-Controller (MVC) framework developed by The Apache Software Foundation as part of its Jakarta project. Struts 2 is built on top of JSP, Servlets, and tag libraries. Struts 2 addresses many major issues in using vanilla Servlets/JSP to build web systems. It solves the problem of controller complexity by removing the workflow logic from the Servlets and directing workflow in an XML configuration file. Struts 2 improves on the limited form support in JSP by adding numerous capabilities to form processing including easy validation, easy error display, and the refilling of form input on form retries from the user’s previous entries. It minimizes the complexity of JSP pages, by supplying a very extensive and flexible set of custom tag libraries for many of the standard operations needed in JSP pages.

Building Java EE / JEE Web Applications using Servlets/JSPs and Struts 2.0 is a five-day hands-on course geared for experienced Java developers new to Java EE / JEE, who need to get up and running with essential Struts 2 development skills. Created in collaboration with several leading JEE and Struts authors and industry experts, this comprehensive course teaches students how to design and program servlets and JSPs, including all the important concepts and hands on labs that will have you building working Struts 2 applications in no time flat. This course provides core Struts 2 knowledge that can be used as the foundation for developing production-quality web applications to a basic level.

Excellent detail about the Spring framework which directly relates to my role as a senior engineer. I found the content and style to be very enjoyable, and would encourage me to ask questions where previously I might not have paid much attention, eg. pom version numbers / spring starters being imported. The focus on the different styles of unit testing was also excellent and I would plan to incorporate in day to day work.

Edward K

First time in my life I have attended remote class and I find it great. Personally I don't feel there is any area which require improvement!

Rishi M

A very good balance of teaching time to lab time. I've done other courses that I found to be much lighter on content and heavy on labs to waste time. This was a refreshing change of pace.

Adam G

Great job overall. Great communicator and explained complex concepts in a simple, easier to understand format.

Jeremy G

Excellent training. Even though it was online, I did not have any issues understanding or getting the answers for the questions I had. The lab exercises are interesting to apply what was learnt. Overall very good training. Thank you!

Anitha

Best programming class I've ever been in, head and shoulders above any thing I took in college as part of a computer science degree. The instructor was thorough and very detailed, he was very good abut explaining all possible scenarios a situation would apply to. The way the albs were structured and the class was conducted was very good for interaction and hand on learning.

Danish J

The instructor was clearly knowledgeable about Java and programming in general. He was very attentive to every student's individual needs and constantly encouraged questions, concerns, student issues to be raised and addressed each one thoroughly.

Mark M

Instructor was beyond phenomenal. He had an in depth knowledge of the course material and always ensured that everyone understood what was being discussed. I really enjoyed the mix of theory and practical examples of each part of the course.

Cillian M

Both the instructor and the course material were very thorough - the course material has many helpful references - the labs were well laid out, making it easy to learn from and get done on time
