ApacheCon EU 2014

Apache Tapestry is a component-oriented Java web application framework with a focus on simplicity, ease of use, and developer productivity. Some of Tapestry’s features include live class reloading in development mode, convention over configuration - eliminating almost all XML configuration, Post/Redirect/Get, and an integrated Inversion of Control (IoC) container, which allows almost all of Tapestry’s behavior to be configured or replaced.
Three years after the last major release of Apache Tapestry, 5.4 is just around the corner. In this talk Uli will give an introduction to Tapestry and speak about the new features of 5.4, such as the new framework agnostic JavaScript layer and Bootstrap integration.

Apache Wicket strives to enable developers to be very productive and craft maintainable web applications. Java EE also enables developers to achieve high productivity. So what happens when you combine both technologies? In this session Martijn Dashorst shows how to leverage the available Java EE technologies such as CDI, JPA, Bean Validation and JAX-RS in your Wicket applications.

With the Tenth Anniversary of Wicket behind us, Wicket is still one of the thriving survivors of the Great Web Framework Wars of the mid 00's. Is there a future for server-side frameworks? In this presentation Martijn Dashorst provides a brief history of Wicket.

With a State of the Wicket, Martijn will look at who is currently using Wicket, the community and current release plans.

The majority of this session will be dedicated to the future of Wicket: does a component oriented, Java web framework have a future in the era of native clients and client side JavaScript frameworks? Martijn will layout the plans of making Wicket more productive for current users, on integrating better with JavaEE technologies and much more.

The ""build more"" in this case means building line-of-business enterprise applications, the stuff that's the operational heart of your organisation.

And the ""with less"" means less resources, in other words in less time, with fewer developers, faster time to market.

But the ""how"" is the interesting bit. In 2012 Jeroen approached Dan with a problem... he wanted to write a bespoke application for his client, a European multi-billion property management company that operates over 60 shopping malls. For various reasons, Jeroen wanted to explore whether Apache Isis could be used as the platform on which to build a bespoke replacement.

Fast forward two years and Estatio (also open source) is in production, and it took about 2 man years (Jeroen and Dan, part-time) to write. We don't think there's a Java framework out there to match Isis for productivity. Let us fill in the blanks.

The first part of the presentation will give an introduction to the Apache Tapestry framework and its core concepts. The talk will cover the pros and cons of component-based web development and how the builtin IOC can help to structure applications and adjust the internal behavior of Tapestry. The first part of the presentation will also focus on the JavaScript stack, which has been completely re-written for the upcoming 5.4 release. The second part of the presentation will share the experience of how Tapestry helped RepRisk solve everyday development tasks, how it improved our development, testing and deployment process​, and why we think Tapestry increased our software quality.
