  • My Case for DTO’s

    In many of my posts about Grails and Flex integration, I take for granted that I use Data Transfer Objects to transfer data between my Grails backend and my Flex frontend. Put simply, Data Transfer Object are pure data containing classes different from the domain entity classes used to store data in the backend. I take it for granted because I’m deeply convinced that it’s the best way to do things and so far, experience has never proved me wrong. But I often get this question in comments or by mail (this is for you Martijn): why bother create an entirely separate class structure and copy data from entities to DTO’s and back instead of just using entities?

  • Flex on Grails, Take 2: Part 3

    At the end of the second article in this series, we ended up with a working application but it was not really ready for the real world because it had one major flaw: the URL of the AMF endpoint was hardcoded in the client in such a way that it was impossible to change after compilation and very hard to handle several environments (dev, test, prod). The solution to that problem is to integrate dependency injection into the mix.

  • Flex on Grails: Take 2

    When I first discovered Flex, one of my first obsessions was how to make it work with a Java backend. I’m a java developer at heart and my Java backend stack of choice back then was Spring/Hibernate-based. That’s why I published a series of full-stack articles that became quite popular. But another obsession of mine has always been productivity so when I discovered Grails, it became my new preferred environment and I started looking for ways to plug a Flex frontend into a Grails backend. All of this work culminated in the release of my Grails BlazeDS plugin which worked great but had a few limitations (only Java DTO’s, run-war instead of run-app, etc.). I mean, it worked great… until it didn’t.

  • Grails/BlazeDS/Flex/iPhone Full Stack Part 2/3

    In the previous episode, we built a simple Grails backend for the todolist application. In this installment, we will create a simple Flex 4 front-end for this backend. The following assumes that you have already installed Flash Builder 4 (formerly known as Flex Builder), either in standalone mode or as an Eclipse plug-in.

  • Grails/BlazeDS/Flex/iPhone Full Stack Part1/3

    A couple of years ago, I published an article on this blog entitled “Flex, Spring and BlazeDS: the full stack!” and this article became very popular. Actually it broke my daily visits record. Today I’m gonna try to break this record again.

  • Grails BlazeDS 4 Integration Plugin

    One of the main goals I’ve been pursuing for a few months is the integration of Grails with Flex 4. I need to rework ConferenceGuide‘s administration backend to make it more ergonomic so that we can cover more events, and ever since I discovered Flex 4 niceties, I couldn’t think of doing that with anything […]

  • My Discoveries of the Year

    Every year, the main reason why I go to Devoxx is to discover new stuff. For me it’s all about technology watch. The internet and RSS feeds are my main tech watch instrument but there is one thing that is harder to get through RSS: feelings. Conferences like Devoxx are a unique opportunity, not only […]

  • Spring, Flex, BlazeDS Full Stack is Back!

    After trying for weeks to integrate Flex and BlazeDS into Grails, in vain, I’ve decided to come back to vanilla Spring/Hibernate for Conference Guide server. And I took the opportunity to upgrade my todolist sample application, the one featured in the article published both on this blog and on the Adobe Developer Connection. Here are […]

  • Grails Flex Integration, version 1.0

    Ever since I discovered Grails, I’ve never stopped looking for the best way to make it work with Flex (I guess for me, the search was NOT over). Why so? Simply because the less time we spend connecting components, mapping objects with the database and dealing with boilerplate code, the more time we have for building gorgeous user interfaces. As for usual web suspects like JSF, GWT, GSP and other HTML/JS-generators, they have never been the best solution for me. So how do we get Grails and Flex to work together?
