You probably know two or three different ways to create Adobe Flash UIs. The most straightforward and expensive one is using Adobe’s Flex Builder. This IDE offers a quick, flexible and reliable way to program a UI in MXML – Adobe’s XML-based UI description language – and ActionScript – the corresponding scripting language to give life to the MXML UI components. For students, Lehman stock owners and other less pecunious people, there is the Flex 3 SDK and a bunch of tutorials on the web on how to teach Eclipse MXML and ActionScript. But did you ever think about using Java to write a Flash UI? You could integrate a fancy Flash UI with your Java application more smoothly, or you could write a Flex code generator in Java (maybe even provide other developers with a DSL that your Java-based generator can translate into Flex applications?). Using only free software, it doesn’t take more than a couple of minutes to create such a Java library for Flex Applications – this tutorial shows you how to do it.

Persistence is to the character of man as carbon is to steel. (Napoleon Hill)

For our second JUG Saxony meeting, we were in the comfortable position of being one station of a little tour of Mr Shaun Smith from Oracle, project lead of the EclipseLink project and product manager of TopLink. Actually, we have to be grateful to the JUG Berlin-Brandenburg for their mediation…Ralph, thank you very much again!

The meeting took place at the Faculty of Computer Science. This time, the meeting has been organized by ubigrate in cooperation with Torsten from Communardo and Kristian from PlanConnect. Thank you again for your support! Jürgen from ubigrate started the meeting and presented the results of the survey we conducted at the first meeting. Interestingly, we followed almost all of the proposals made by the participants of the first meeting – especially we hit the 2nd most requested topic for a talk, which was “Java Persistence Frameworks”. As last time, the hosting company was presented (this time by myself).

Interessante Dinge haben sich in den letzten Jahren im JAXB-Umfeld getan. Während diese Technologie 2004 noch nahezu unbrauchbar recht hakelig war, ist mit JAXB 2.0 (aka JSR-222) bzw. JAXB 2.1 ein Entwicklungsstand erreicht, welcher zusammen mit nicht-standardisierten Features (z.B. innerhalb der Referenzimplementierung JAXB RI) den Einsatz von JAXB in industriellen Anwendungen erlaubt. Im folgenden soll speziell auf XJC, den XML-to-Java-Compiler der Referenzimplementierung, eingegangen werden. Im Zusammenhang mit allen JAXB-Fragen sollte stets Kohsuke Kawaguchi’s Blog besucht werden – Herr Koshuke ist sicher der Hauptentwickler der Referenzimplementierung. Weiterlesen »
