Lessons

• The set of standard actions provided by JSP is minimalist (6 tags), but the example suggests they are quite flexible, and can implement applications with non-trivial logic.

  • We needed very few Java scripting inserts.

• Session tracking and error handling are particularly elegant.

• Caveats:

  • The lack of iteration in the standard actions means that sometimes the Bean has to take over HTML generation, e.g. for tables and menu elements.
  • The trigger+linked properties approach works, but seems slightly contrived for complex operations?
