Spent my Sunday fiddling with Apache Struts 2.0.6. I chose to experiment with the distribution targeted for JDK 1.4.2. After going through the samples i must say that migrating our applications from Struts 1.X will take a big effort and lots and lots of patience because we have to rewrite almost 50% of the codes, save the DAOs and Business Delegate classes. It's tempting to have the dependency injection feature in our apps plus other features like Ajax tags, but i always remember the mantra: if the software ain't broke don't fix it. Rewriting the apps might reintroduce the bugs we squashed.
Anyway Struts 2 impressed me. The combined forces of WebWork and Struts indeed gives fruitfull result. To me the best feature in the framework is the ability to intercept your code via interceptor class. Now AOP became a clearer concept for a 3 year Java developer like me. Altering one's perception of the world does take a practical example to make him/her see..in my case theories alone doesn't work...i need practical examples.
Since Struts 2.0.6 is still in GA (General Available) release i'll assume there will be more things to come(especially the plugins) and the framework will get better and better.Till then i'll depend on our current struts 1.2.x.
which has been our team's de facto standard for web based enterprise applications.
