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.
The 0.9 draft of the SCA Java EE Integration specification, just published by the Open SOA collaboration, defines the integration of SCA and Java EE within the context of a Java EE application, the use of Java EE components as service component implementations, and the deployment of Java EE archives either within or as SCA contributions.
OpenXava provides a framework that allows developers to quickly and productively create web applications and portlets. Version 3.0 allows users to take full advantage of JPA, creating complex user interfaces and applications easily.
The EJB 3.1 expert group recently released an early draft of the specification, containing some significant new features as well as a continued simplification of the EJB programming model.

Henning Blohm, Java EE Software Architect at SAP and Co-Chair of the SCA-J Technical Committee provides his perspective on Service Component Architecture as a cross-technology programming model integration. He argues that for vendors, SCA lowers the marginal costs of providing implementation or binding technology to its users and for users SCA reduces the marginal costs of making use of them.
In this panel discussion from QCon San Francisco, several influential leaders of the software development community discussed and debated the future of the Java language and APIs based upon the lessons we have learned from the past. Topics included static versus dynamic languages, removing code from Java, forking the JVM, and the next big programming language.
In this interview from QCon San Francisco, SpringSource CEO Rod Johnson discusses the origins and philosophy of Spring, the Spring Portfolio, Spring Web Flow, Spring Batch, Spring.Net, the partnership with Tasktop Technologies, and community involvement and utilization of Spring.
We've come a long way from the first versions of J2EE. We've learned to avoid invasive programming models, we've developed a rich set of frameworks and APIs, we know how to develop apps based around simple objects. Are we there yet? Most of us would answer no. If we're not there yet, then where are we headed next? Spring founder Rod Johnson explores this issue. Recorded at JAOO Sept 2006.
A lightweight approach with a rich domain model used directly in web-tier can increase both quality and speed of development. This case study, recorded at Javapolis, looks at a Tapestry+Spring+Hibernate project by Nordija, how it was architected, how testability was introduced, and the level of simplicity achieved using the lightweight approach.
