Sun continue work with JDO 2.0
Sun have submitted a JSR (243) for the next version of the JDO specification, 2.0.
As JDO is seen as a viable alternative to Entity Beans, it makes you wonder were Sun is headed with this, especially as they are also working on the EJB3.0 spec.
It would make sense to leave Entity bean support in future J2EE specs for backward compatibility, but surely they must see that the majority of everyone else is going in the direction of Object persistence (with Hibernate and JDO), while Sun are still beating Entity Beans to death? And the majority of those who have implemented systems with Entity Beans are moaning about how complicated the development is, poor performance, bad fit with the Business Domain Model etc?
Developing Webapps with Struts, Spring and Hibernate
O’Reilly’s OnJava.com site have a good article on developing webapps using a combination of Struts, Spring and Hibernate.
The section on using Spring is very interesting – using Spring gives you declaritive control over the dependencies between objects, and therefore also between application application layers. This can be used to further reduce coupling between code in each architectural layer, for example between Presentation and Business, and between Business and Persistence.
From what I understand about the use of Spring (or other ‘microcontainers’), it gives you a level of abstraction and allows you to reduce direct coupling between Classes by being able to define relationships and dependencies declaritively (rather than in actual code). I think this can be compared to what the struts-config.xml gives you for webapps, in that it reduces coupling between web pages and page navigation, and the logic that controls that navigation.
