XINS is an open-source Web Services technology, supporting SOAP, XML-RPC and REST. It consists mainly of an XML-based specification format and a Java-based implementation framework. From its specifications, XINS can generate HTML, WSDL, client-side code, server-side code and test forms. Users do not require knowledge of any complex formats, such as XML Schema.

The Eclipse Web Tools Platform (WTP) project extends the Eclipse platform with tools for developing J2EE Web applications. The WTP project includes the following tools: source editors for HTML, Javascript, CSS, JSP, SQL, XML, DTD, XSD, and WSDL; graphical editors for XSD and WSDL; J2EE project natures, builders, and models and a J2EE navigator; a Web service wizard and explorer, and WS-I Test Tools; and database access and query tools and models.

HiveBoard is an online shared whiteboard conferencing system.

JBoss IDE for Eclipse tools are available through the Eclipse Install/Update Manager or as a zip bundle (below). Installing JBoss IDE for Eclipse using the Eclipse Install/Update manager is preferred since it allows the automatic notification and download of future JBoss IDE for Eclipse releases. To learn how to install/upgrade JBoss IDE for Eclipse, please refer to the JBoss IDE for Eclipse Installation Guide. The following download bundles are for those who do not wish to use the Eclipse Install/Update Manager.

This Howto describes how to create a Web Service Endpoint and a J2EE client that uses this web service. The endpoint will provide a method for computing the compound interest from an initial investment, an interest rate (percent) and a time quantity.

La technologie de persistance objets J2EE, les Entity, a beaucoup évolué depuis sa création. Il reste pourtant toujours une des bases de la théorie objet qui n'est pas couverte : l'héritage. Cette faiblesse est souvent un argument utilisé par les détracteurs des EJB Entity. Ce besoin est pourtant plus un confort des technologies objets qu'une nécessité. Mais, comme avec l'ensemble des technologies J2EE, un bon design patterns nous rendra accessible cette fonctionnalité.

The evolution of Web-related technologies has changed the way applications in an organization communicate with customer and partner applications. Like every popular technology, Web services came like a wave and have assimilated deeply into IT organizations. Having revolutionized the IT world, Web services are here to stay. Thus, to compete in the market space, certain parts of your enterprise applications must be exposed as Web services.

Considering what they are, Enterprise JavaBeans are "easy". As of EJB 2.0 they became even easier. And as of EJB 2.1 you can generate Web services from EJBs. You could say EJBs are too easy. You can create EJBs using an IDE with just a few mouse clicks. What could be easier? A major value of EJBs is their contribution to a set of business standards. EJBs enable scalable distributed transactions and connection to a vast array of Internet services - a modern version of what mainframe transaction systems used to do. However, no matter how easy EJBs may look, you need to be discressionary and careful about usign them. Scalability and distributed services, the platform architecture for EJB and J2EE have been a complex undertaking. And to understand how to write, integrate, and deploy EJBs, you need to understand this platform architecture.

The JavaTrademarked EE 5 Tutorial is a guide to developing enterprise applications for the Java Platform, Enterprise Edition 5 (Java EE 5). Here we cover all the things you need to know to make the best use of this tutorial.

The J2EETrademarked 1.4 Tutorial is a guide to developing enterprise applications for the Java 2 Platform, Enterprise Edition (J2EE) version 1.4. Here we cover all the things you need to know to make the best use of this tutorial.

An entity bean with container-managed persistence (CMP) offers important advantages to the bean developer. First, the EJB container handles all database storage and retrieval calls. Second, the container manages the relationships between the entity beans. Because of these services, you don't have to code the database access calls in the entity bean. Instead, you specify settings in the bean's deployment descriptor. Not only does this approach save you time, but also it makes the bean portable across various database servers.

L'objectif de ce manuel est de guider l'utilisateur tout au long de l'installation de JOnAS et de lui permettre de faire fonctionner une première application à base d'EJB. Il permet également d'aider à exécuter une application plus complexe utilisant les EJB pour accéder à une base de données.

Ce tutorial est en stand by, nous désormais sur le projet JOFFAD pour lequel nous sortirons sous peu un tutorial ( EJB, Struts, JUnitEE.... ). N'hésitez pas à nous contacter pour participer à JOFFAD !

Trop de configurations (ah la verbosité d'XML :-) éparpillées dans plein d'endroits. Cette verbosité est telle d'ailleurs qu'elle s'accompagne obligatoirement des plug-ins dédiés aux principaux IDE. Résultat : on gagne encore en complexité, avec l'installation de ces plugins dans l'IDE (gestion des versions de ces plug-ins, compatibilité avec les versions de l'IDE lui-même, ...) Cerise sur le gateau, vous êtes maintenant liés (à vie au moins !) avec votre IDE (pas si favori que ça parfois) sur un projet donné. Hors de questions aussi de laisser à chaque développeur (ou binome) le choix de son IDE. Serait-ce une bonne idée ? Dans le même ordre d'idées, les insuffisances d'une architecture ultra-générique ont vu des extensions propriétaires côté application servers. (deployment descriptors propriétaires) Le framework qui se veut universel se heurte à la réalité de chaque projet, et la promesse de portabilité initiale s'envole.

Each pattern in this catalog includes sample code from JavaTM BluePrints reference applications such as the Java Pet Store sample application.

This is a platform for java programmers to help each other and to help promote Java as a language, as a technology, as a platform and as a tool for providing enterprise solutions.
