A previous post already has an extensive review of the JSpring conference so I’ll follow up to that one.
The concern that Duncan Mills stated was shared by other speakers and also by many attendees. It boils down to ‘too complex and a lack of clarity and direction’. Now is the time to reduce the complexity and probably POJO’s, EJB 3.0, JSF and Meta Frameworks like Spring and ADF will play a major role.
Another hot issue on JSpring is SOA. A very nice presentation and demo on JMS and JMX gave a brief glance of the possibilities. All application servers provide in their latest versions support for JMS and offer management and reporting functionality based on JMX.
EJB 3.0 is currently a major buzzword in the J2EE community. A session on EJB 3.0 and JDO 2.0 (yukh, since technology advances soo fast the version number becomes part of the name) was therefore very much welcomed. Almost everybody agrees that EJB 3.0 will be a revolution. But actually this is true for the entity beans, and to a lesser extend for sesison beans and message driven beans. Both EJB 3.0 and JDO 2.0 are expected later this year. The speaker did not express his preference for one of the technologies, but explained that both have different philosofies an purposes: JDO is more object focussed while ejb is more entity focussed. Meanwhile we got some real good impressions of Kodo, a framework for OR mapping.
To summarize, JSpring and its counterpart JFall have matured in a very short time to an important event with good speakers and hot subjects.
The presentations are available at the JSpring sessions site.
