We just finished up a little blog post talking about upgrading the sample app from 5 Days of Wicket to Wicket 1.4 which was just released. Learn about a simple conversion to 1.4 of MysticPaste.com on Mystic’s blog. We review some of our findings:

• Generify everything for the most benefit
• Deprecated classes now exist making some of your code obsolete
• Some configuration changes and libraries move around

Overall the process of upgrading took a little under 30 minutes, and for a medium to large code base probably would take a little less than a day from estimates we’re hearing.
