Tracking change and innovation in the enterprise software development community
In this presentation from QCon London, William Soo and Meeraj Kunnumpurath discuss the Voca transaction processing system architecture, the previous Mainframe-based architecture, architectural challenges and requirements, the new Spring and J2EE-based architecture, upcoming challenges for Voca, and technologies to watch for in the future.
JBoss Seam is a new full-stack web application framework that unifies and integrates Ajax, JSF, EJB3, Portlets, and BPM. This article is an editted excerpt of chapters 1 and 2 from the first (to-be-released) book on Seam by Michael Yuan and Thomas Heute. It explains what Seam can do and grounds the concepts with a HelloWorld example.
An ambitious and key part of Java EE 6, the Web Beans specification spans JSF/EJB integration, context management, dependency injection and AOP. The specification is currently in public review and the review period has been extended into 2009. An Alpha build is also available. InfoQ talks to Gavin King to find out more about the state of play of the specification and progress to date.
Exadel’s Flamingo project is a tool for bootstrapping RIA applications built with Java backends. The tool offers support for both Seam and Spring in the middle tier. On the presentation tier, Flamingo supports both Flex and JavaFX. The tool has a similar approach to bootstrapping applications as the AppFuse project available for more traditional Java web tier frameworks.
Spring and JBoss Seam frameworks provide different set of features for developing enterprise web applications. Is it possible to use these two frameworks together in web applications? This topic was the main focus of a recent article and a java community forum discussion on how the strengths of each of these frameworks can be used together.
In this article, Eelco Visser summarizes his approach to design WebDSL, a domain-specific language for developing dynamic web applications with a rich data model with a target architecture based on JBoss's Seam. He discusses paradigms and challenges of Language Engineering while sharing some of the lessons he learned along the way.
Jacob Orshalick recently explored Seam's nested conversation model and related timeouts using Seam's demo booking example.
This past week Matt Raible gave a presentation at ApacheCon comparing Java Web Frameworks. This is a follow up to a presentation he gave a few years ago. It is interesting to note the changes in the frameworks being evaluated.
Nolan Wright thinks server-assisted MVC implementations are a thing of the past and that Services, Ajax and DHTML can greatly simplify the way we build web applications.
