"I encourage (actually I dare you) to those who have never even touched a portal to take the JBoss Portlet Bridge for a test drive. It takes 1 download (GateIn bundled with JBoss) and one maven archetype to get started. You can choose from any combination of plain JSF, Richfaces, and Seam with mvn archetype:generate -DarchetypeCatalog=http://bit.ly/jbossportletbridge from the command line."

"Community Dashboard Framework (CDF) is a project that allows you to create friendly, powerful, fully featured dashboards on top of the Pentaho BI server. Former Pentaho dashboards had several drawbacks from a developer's point of view. The developing process was awkward, it required know-how of web technologies and programming languages, and basically it was time-consuming. CDF emerged as a need for a framework that overcame all those difficulties. The final result is a powerful framework featuring the following: . It is based on Open Source technologies. . It separates logic (JavaScript) of the presentation (HTML, CSS) . It features a life cycle with components interacting with each other . It uses AJAX . It is extensible, which gives the users a high level of customization: . Advanced users can extend the library of components. . They also can insert their own snippets of JavaScript and jQuery code. CDF can be used: . As part of a Pentaho solution. This is the most common scenario. . In a standalone mode as an alternative to the Pentaho User Console . Integrated with Portlets, PHP applications, intranet portals and even desktop applications. "

The aim of this paper is a brief introduction to MDA technology and a summary / comparison to the approachments to MDA of AndroMDA and Acceleo, intending to be a practical and understandable summary Introduction Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. It was launched by the Object Management Group (OMG) in 2001 The Model-Driven Architecture approach defines system functionality using a platform-independent model (PIM) using an appropriate domain-specific language (DSL). One of the main aims of the MDA is to separate design from architecture. As the concepts and technologies used to realize designs and the concepts and technologies used to realize architectures have changed at their own pace, decoupling them allows system developers to choose from the best and most fitting in both domains. The design addresses the functional (use case) requirements while architecture provides the infrastructure through which non-functional requirements like scalability, reliability and performance are realized. MDA envisages that the platform independent model (PIM), which represents a conceptual design realizing the functional requirements, will survive changes in realization technologies and software architectures.
