Back in 2006 InfoQ covered a story about Nuxeo, an open source Enterprise Content Management (ECM) specialist company, who had announced that it was changing its core technology platform from Python to Java. Four years on we caught up with Eric Barroca, CEO at Nuxeo, to find out how that conversion went, and to explore their new technology stack and position in the ECM industry.

Boris Lublinsky discusses task management in the jBPM and then demonstrates how to implement four advanced user interaction patterns(4-eyes principle, nomination, escalation, and chained execution) using JBoss and the jBPM. He also notes the advantages and limitations of these patterns.
Mark Little presents the constituents of a modern SOI and where open source implementations stand in terms of standards, tools, ease of use, performance and reliability, making a case for using open source against close source solutions.

Dan North discusses an example of rearchitecting an application without rewriting it from scratch, and explains general strategies for a holistic rearchitecture such as changing the team culture, removing obsolete technologies, allowing mistakes to be made (and learned from), transitional architectures, introducing bounded contexts, refactoring and emergent simplicity, and rotating through roles.

InfoQ recently sat down with Peter Kriens of the OSGi Alliance to learn more about OSGi. Kriens discussed OSGi's origins in the mobile space, it's integration with Eclipse, the current integration work with Spring, and the future R5 specification. He also discussed the ongoing debate over OSGi and JSR 277, and gave his perspective on what an ideal solution would be for modularity at the JVM level.
