A new article by I. Drobiazko and R. Zubairov introduces v. 5 of the Apache Tapestry component-oriented web framework. The tutorial shows how to create a component and covers IoC in Tapestry and Ajax.
Java web frameworks are increasingly adopting the ability to change portions of a web application and see the results immediately without restarting the server. This capability reduces the cost of the compile-build-test cycle, and helps to compete with the features of dynamic-language web frameworks such as Ruby on Rails or TurboGears.
Apache Tapestry has released a preview of Tapestry 5, a complete re-write that adopts Java annotations over XML, POJO component classes over base class inheritance, and promises significant performance improvements.
A lightweight approach with a rich domain model used directly in web-tier can increase both quality and speed of development. This case study, recorded at Javapolis 2005, looks at a Tapestry+Spring+Hibernate project by Nordija, how it was architected, how testability was introduced, and the level of simplicity achieved using the lightweight approach.
