Abstract : The presentation aims to show the open source components, the methods and the technologies we used to develop a portal client for a commercial ERP. During the sessions, we will cover four topics :

* The ERP integration (How the editor opened his solution to developers.) * The global architecture (The different layers of the application (Domain model, DAO, Service...) and its integration with the J2EE services.) * The Open Source components we choose (the components we selected to develop the application (JOnAS, JORAM, Hibernate, GWT) * The methodology (Test driven development, continuous build )

The goal is to show how we integrate an existing solution based on different technologies to build our own loosely coupled solution.
