Usually, when you want to build a Java application with some dependencies, the best is to use a build tool that will download the dependencies for you *and* configure your IDE for you. For a small project like the one you describe, i believe it's simpler to use Maven. Maven uses a pom.xml file that describes the dependencies and some plugins, you have one for tomcat by example. There is an eclipse plugin called m2eclipse that configure eclipse from the pom.xml (you have to activate an option in the m2e plugin). There are a lot of tutorial on the internet on how to use Maven with Eclipse. Once you have played a little with Maven, dependencies should be a problem from the past and you should be able to focus on what you want to do :) > Thanks. > Simon regards, Rémi
