Currently we use appfuse 1.9.4. I'd love to upgrade to appfuse 2. However, as I understood that appfuse 2 uses java 5 and my company is unable to move to Java 5 yet, because we use websphere 5.1 which supports java 1.4. Is it possible still upgrade to appfuse 2, still use xdoclet and everything else?
The short answer is "no". The long answer is you could probably migrate your Ant-based application to Maven 2 and use a lot of the same plugins AppFuse user. You could also configure Retroweaver ( http://retroweaver.sourceforge.net) to make AppFuse's artifacts compatible with 1.4. Struts 2.x does this and makes them available as 1.4-compliantJARs. I don't know if it would work, but you could try. The current Hibernate tutorial only covers annotations and we use an Annotations-based SessionFactory. You probably couldn't use the GenericDao either because it uses Generics. If you're interested in contracting my services to make AppFuse 2.x work with 1.4, we might be able to work something out. ;-) Matt Qin
