Outils Maven, J2EE, et archetypes

10 mai 2008 par Yohann CIURLIK

Rien de bien compliqué ici… Vous travaillez sur des applications web J2EE (clients légers) et vous utilisez Maven. Ce qui suit peut alors vous intéresser. Pour les autres, c’est le temps de découvrir de nouveaux outils…

C’est quoi Maven ?

Maven est un outil open-source de build, un peu à la maniére d’Ant (mais plus puissant) pour les projets Java.

Conçu pour supprimer les tâches difficiles du processus de build, Maven utilise une approche déclarative, où le contenu et la structure du projet sont décrits, plutôt qu’une approche par tâche utilisée par exemple par Ant ou les fichiers make traditionnels.

Maven gère les dépendances simplement via quelques lignes de code. Il n’est plus question de télécharger vos archives, vos librairies mais simplement d’indiquer lesquelles vous utilisez dans votre projet pour que Maven les télécharges et les ajoutes au “build path”. Vous trouverez un excellent article de présentation sur développez.com.

Donc Maven est un outil bien pratique. Vous développez des applications Web J2EE et vous souhaitez utiliser le fameux builder pour vos applis. Il existe des architectures types (archetypes) d’applications Web pour Maven. Cela simplifie le démarrage de projets Web. Les voicis :

ActiveMQ	This archetype allows you to generate a template for a web application that uses ActiveMQ. The sample webapp allows a user to type in and send a message which will then be added to a Message Log. Source: maven-archetype-ActiveMQ.zip Artifact ID: maven-archetype-ActiveMQ Version: 5.0.0
DOJO	This archetype allows you to generate a template for a web application that uses DOJO. The sample webapp displays “Hello World!” that the user may fade out or fade in. Source: maven-archetype-DOJO.zip Artifact ID: maven-archetype-DOJO Version: 1.0.2
cometd	This archetype allows you to generate a template for a web application that uses cometd using jetty’s ContinuationCometdServlet. The sample webapp echoes messages being sent to the server back to the client. Source: maven-archetype-cometd.zip Artifact ID: maven-archetype-cometd Version: cometd-api: 0.9.20071211, cometd-bayeux: 6.1.7, jetty: 6.1.7
DWR	This archetype allows you to generate a template for a web application that uses DWR. The sample webapp allows the user to enter his name to display a customized “Hello World” greeting. Source: maven-archetype-DWR.zip Artifact ID: maven-archetype-DWR Version: 2.0.2
JSF	This archetype allows you to generate a template for a web application that uses JSF. The sample webapp allows the user to enter his name to display a customized “Hello” greeting. Source: maven-archetype-JSF.zip Artifact ID: maven-archetype-JSF Version: 1.2_07
SiteMesh	This archetype allows you to generate a template for a web application that uses SiteMesh. The sample webapp displays “Hello world!” and the current date. Source: maven-archetype-SiteMesh.zip Artifact ID: maven-archetype-SiteMesh Version: 2.3
Spring	This archetype allows you to generate a template for a web application that uses Spring. The sample webapp displays “Hello world!”. Source: maven-archetype-Spring.zip Artifact ID: maven-archetype-Spring Version: 2.5
Spring JPA	This archetype allows you to generate a template for a web application that uses Spring and Hibernate JPA. The sample webapp displays “Hello world!” and allows you to modify a list of people’s names and professions. The webapp requires a database to be running. The sample uses HSQL. The sample webapp is capable of running the database by typing: mvn install. Then, in another window, run the webapp by using the command: mvn jetty:run. To try the sample webapp, point your browser to http://localhost:8080.

Struts	This archetype allows you to generate a template for a web application that uses Struts. The sample webapp allows the user to enter his name to display a customized “Hello” greeting. Source: maven-archetype-Struts.zip Artifact ID: maven-archetype-Struts Version: struts2-2.0.11, struts-taglib-1.3.9
Tapestry	This archetype allows you to generate a template for a web application that uses Tapestry. The sample webapp displays “Hello world!” and the current date. * To view the sample webapp, point your browser to http://localhost:8080/app. Source: maven-archetype-Tapestry.zip Artifact ID: maven-archetype-Tapestry Version: 4.1.3 For version 5.0.5, you can refer to this archetype.
WebWork	This archetype allows you to generate a template for a web application that uses WebWork. The sample webapp allows the user to enter his name to display a customized “Hello” greeting. Source: maven-archetype-WebWork.zip Artifact ID: maven-archetype-WebWork Version: 2.2.6
Wicket	This archetype allows you to generate a template for a web application that uses Wicket. The sample webapp displays its own version of “Hello World!”. Source: maven-archetype-Wicket.zip Artifact ID: maven-archetype-Wicket Version: 1.2.6
