Hi Pascal, J2 is still very young so there really isn't much of a how to. As for a feature comparison, I will give you a brief run down of some major points in J2.
- J2 is not built on any web framework J1 is built on Turbine. - J2 uses pipeline to handle all requests to portal which makes extending J2 much easier. - J2 uses a pluggable PersistenceStore for persistence operations, which is currently backed by OJB. We are planning to implement a Hibernate and JDO version very soon. All DAOs use the PersistenceStore which protects us from API lock-in. J1 used Torque directly and did not provide an easy avenue for changing the persistence layer, plus Torque requires your business objects to extend Torque-specific classes. - J2 will eventually be made up entirely of Pico components which can be easily swapped out or used outside of J2. This also makes unit testing extremely simple and allows us to perform fine grained tests at the component level without having to start the entire Jetspeed 2 engine to test e.g. we can have a lot of unit tests that run very quickly. - We are also working towards JMX management using Jetspeed 2 Cornerstone's JMX module. - portlet decorations (skins, themes, etc) are much easier to create. We are taking great care to make look and feel development as natural as possible for web developers. - All user preferences, including portlet preferences, are stored using the java.util.prefs api. Our current prefs implementation uses the PersistenceStore discussed above. - J2 Security will be done using a JAAS implementation. The current thought is to assign java.util.Acl to individual portal resources like Portlets, PortletEntities, Pages, Folders, etc. - Profiling will be pluggable. David Taylor can expand on this since the Profiler is his baby ;) Those are some major points, I'm sure I have missed some.
