Migrating the Spring Pet Clinic to Java EE 7

Since Java EE 6, we have seen a number of folks migrate from the popular Spring Framework to vanilla Java EE, especially in the GlassFish, JBoss and TomEE ecosystems. A small handful of these folks have spoken at JavaOne and we will likely have a few more this year as well - see the embedded slide deck below from JavaOne Rock Stars Bert Ertman and Paul Bakker.

Recently Thomas Wöhlke has taken this further by migrating the entire Spring Pet Clinic example application to Java EE 7 and RichFaces. You can learn more about the effort here. His port works well on both GlassFish and WildFly. Incidentally, the Cargo Tracker Java EE Blue Prints application is also a port of a well known older Spring and native Hibernate application.

Perhaps this is worth a look if you are considering such a migration for your own good reasons?
