This blog entry covers a series of impressions from a presentation made by Gaving King who covers the technology stack made up by Hibernate/JBoss/Red Hat, compared to that of a presentation given by Spring technologist's
# Presentation style: * The presentations by the Spring guys are always very professional, with the right level in technology details according to the nature of the event, the structure well organised, and seemingly well rehearsed. * Gavin's presentation is, again, more casual, just like a technology chat. I don't know how much the other people in the audience know about Web Beans and Seam, but Gavin lost me a few times because I haven't been following what's happening in the JBoss world... # Technology inclination: * The Spring guys can be very pedantic (in a good way), always emphasising best practices, such as programming to interfaces, abstraction levels, separation of concerns, etc. * Gavin is more pragmatic. Interfaces did not even make it to his slides. His Web Beans JSR recommends to make business interface optional for EJB 3.1 in Java EE 6. He reckons AOP is too complex for ordinary Java developers, there are only a handful of cross-cutting concerns, and EJB interceptors are enough to get the job done. # Hostility: * Spring guys rarely publicly show their hostility towards JBoss, though in after session chats, they describe JBoss Seam as a "big hack", "annotation hell", "technologically inferior" and "would have been just another web framework were it not for Gavin King's fame". * Gavin is more straight forward, rubbished Spring guys as "AOP nerds" during the session, and I wouldn't be surprised if he called Spring "XML hell". He deliberately omitted Spring when he enumerated the open source frameworks that have influenced Java EE
