Using Tomcat Ant tasks or using Ant to manage Tomcat, whatever you prefer. In the last post, about the directory structure of a web application, I found a little tricky to update the application every time I made changes on it.

In this post, we are going to create a simple Java EE Web application from the scratch. The goal of this example is to show the folder structure used in the development process of a Java EE Web application.

Installing Apache Tomcat on Ubuntu

Keeping the same folder structures used in previous posts, Tomcat 6 will be

Java EE application tiers, containers and components

2009-11-15T12:00:00.007+01:00

At first, the aim of this post was to talk just about the Java EE containers, but then I thought it would be a good idea to include a few words about the components hosted by these containers, and finally, I ended up wrapping all this stuff with the typical tiers of a Java EE application. Thus, the post title. This paragraph summarizes what is being explained on the whole article. Java EE

The installation will be done within the user's home folder, check the "Work area" post if you want to see clearly the folders structure used during the installation. Once it is installed on the system, we will test it with a tiny example to see the most basic functionalities. Apache Ant is an open

Work area

2009-11-01T09:00:00.008+01:00

All the test will be done on the same host, and all the software installed will use and respect the same folder structure. This structure will be placed within the user's home folder, which is not the most common location to place the software programs, but this will allow us to install everything without requiring root privileges. Moreover, this will force us to be aware and take care of every
