Op Artima staat een interessant interview met Scott Blum, de Google engineer die verantwoordelijk is voor de Java-naar-JavaScript compiler in de Google Web Toolkit. Zoals ze het bij Artima zelf samenvatten:

A key feature of the Google Web Toolkit (GWT) is that it allows developers to write browser-hosted Web applications entirely in Java, and have GWT translate that Java code into browser-specific JavaScript. In this interview with Artima, Scott Blum, the Google software engineer behind GWT’s Java-to-JavaScript compiler, talks about the challenges of turning Java source code into JavaScript.

Op de Javapolis presenteert Alex Russel, de huidige voorzitter van de Dojo foundation, alle ins en outs van de Dojo toolkit.

Dojo is een open-source JavaScript toolkit die bedoeld is voor het maken van ‘responsive web applications’. Natuurlijk maakt Dojo gebruik van AJAX-technologie, maar dan gegoten in een bruikbaar framework, met event handling, server side messaging, allerlei widgets, etc. Belangrijk is dat je zelf ook relatief eenvoudig custom widgets kunt maken met Dojo, door gebruik te maken van templates.

JavaScript is not a bug

Zoals altijd moet ook bij het gebruik van JavaScript afwegingen gemaakt worden. In dit geval is dat onder andere dat het langer duurt voordat de web pagina beschikbaar is, omdat allerlei JavaScript code geladen moet worden. Dit gebeurt meestal synchroon. Daar staat een grotere flexibiliteit tegenover nadat de pagina is geladen.

Interactive maps are becoming more and more widespread in modern web applications. However, although many of today’s web applications could make good use of integrated mapping software, development teams often shy away from the complexity of integrating a full-fledged geographical database system.

Two relatively recent technologies, Google Maps and Ajax, can make life considerably easier in this area. This article is designed to give you a rapid introduction to both Google Maps and Ajax, and to let you get your own interactive maps up and running quickly and easily.

Web applications don’t have to be about HTML. Rich client-side environments offer a better end-user experience but demand some rethinking of the web app client-server relationship. Mark Eagle shows how you can use Macromedia Flex to bring rich applications to Flash-equipped browsers. [ onjava.com ]

With so many web application frameworks available, there’s little point reinventing the wheel, especially when Struts offers remarkable extensibility. Sunil Patil introduces the three basic means of extending Struts to achieve custom web application behavior. [onjava.com]

Anders dan de titel van de JSR 223 zou doen vermoeden, zijn de leden van deze JSR uiteindelijk op een algemener scriptingmechanisme uitgekomen dan de smallere opdracht die alleen uitging van webscripting. De JSR is nu in early review, dus dit is een impressie van wat er gaat komen.

Deze sessie was geranked als ‘Advanced’, maar had beter ‘Introductory’ kunnen zijn. Functies die we in web technologie gebruiken zijn veelal het afhankelen van de user request, het opslaan van een bepaalde state, het navigeren tussen verschillende pagina’s en dynamisch genereren van content. Kijkend naar de mogelijkheden die er zijn voor de webtier dan kun je ze ruwweg verdelen in Foundation technologies (servlet, portlet, JSTL, JSP) en Framework technologies (Struts, JavaServer Faces). In de rest van de sessie worden deze technologieen verder behandeld.
