In my five-day class last week, we spent most of the time covering
Struts 2 from the ground-up, and I made comparisons to Struts 1 along
the way. The course uses the MailReader as a running example. On day
five, after we had built our own Struts 2 MailReader, we went back to
the Struts 1 version. We deployed the Struts 1 MailReader WAR, and
then started converting it to Struts 2, page by page. We got a good
start, and it really helped show how the versions differ.
For my "three-hour tour" at ApacheCon US, I was thinking of covering
the high-points, and then go to work on converting the MailReader,
page by page. (Encouraging people to follow along on their own
laptops.)
During the high-points presentation, I thought we might show a
struts-config.xml and then the same thing as a struts.xml
configuration. Ditto for the Actions and pages. After covering the
basics, we could spend the rest of the time migrating the MailReader,
live and direct.
Is that the sort of thing you had in mind, Matt?
Yes. I expect the audience I'm presentation to to be familiar with
Struts 1.x. I'm sure it's good to do an intro to Struts 2.0 as well,
but overall I'd like to have them leave a 1.5 hour presentation with
the knowledge they need to convert a Struts 1.x app, as well as
greenfield a Struts 2.0 application. Migrating an existing project in
real-time is a good idea/demonstration.
