Opleiding: Tomcat Administration

Tomcat Intro

The course Tomcat Administration starts with discussing the different installation options. Next it is shown how Java web applications using servlets and JSP's can be deployed on the server. The web application structure and configuration options with the deployment descriptor are also covered.

Tomcat Architecture

Participants will become familiar with the internal architecture of the server, with JMX (Java Management Extensions) and the use of JMX to manage and monitor the server.

Virtual Hosting

Attention is also payed to the setup of virtual hosting and the different ways to secure web applications using authentication and SSL.

Load Balancing

It is further discussed how to integrate with the Apache Web Server which may serve the static pages or which may have the role of load balancer. The way Tomcat can be configured to enable Web applications to connect to databases is also a course subject.

Clustering

Finally it is discussed how to configure a cluster to ensure the failover in cases of server crashes and to enable the scalability of applications.

JMeter

The JMeter tool will be used to test the performance of Web applications.

Audience Tomcat Administration Course

The course Tomcat Administration is intended for System Administrators and Web Developers who need to administer and control the Tomcat Server and who need to deploy applications onto it.

Prerequisites Course Tomcat Administration

Participants should be familiar basic computing skills like browsing the Web and accessing the directory structure. Knowledge of Web Applications and other Web Servers is beneficial.

Realization Training Tomcat Administration

The theory is covered using presentation slides. The concepts are further explained using demos. The theory is alternated with exercises.

Certificate Tomcat Administration

Attendants receive a certificate of participation in Tomcat Administration after successful completion of the course.
