Flex 4 is Here! Go forth and build better software!

Flex 4 and its counterpart, Flash Builder 4, are now publicly available! We’ve also launched a new flex.org and added a ton of new Flex 4 samples in Tour de Flex!

Rich Internet Applications are the next generation of software. For the first time in the history of software the goal is not to simply collect or interpret data, but to make those tasks productive and simple. RIAs move us up the hierarchy of user and business needs. It is unproductive to change technologies and create the same old stuff. We change technologies because they provide new value like closing more deals, reducing task completion time, or gaining customer loyalty.

I got into Flex 1.0 about six years ago because I could more easily deliver usable software with Flex than I could with any other technology. A key aspect to creating more usable software is working with designers. The new Spark component model in Flex 4 sets the foundation for developers and designers to work more closely together using tools such as Adobe Creative Suite and Flash Catalyst. This is what sets Adobe apart in the RIA landscape. Designers use Adobe’s creative products. The key to building better software is creating ways for designers to more easily work with developers.

By bringing together designers and developers, Flex 4 enables a world of better software! I’m truly excited to see the amazing things you will build with Flex!

    I read your post regarding the Adobe flex use in creating Rich internet application with using Java as back-end.
    Basically, I want to know that whether the front-end of Adobe Flex can be given to a java desktop application. It is like using flex in place of (or with) Swing. Is it possible?


  • Linux User

    Any word on Linux support? Even unofficial alpha versions? Would love to be able to upgrade to Eclipse 3.5! Would it be possible to grab the windows eclipse plugin jars and integrate into a linux install?

  • The last I heard about Flex Builder for Linux was that it was dead (e.g. http://www.infoq.com/news/2009/05/flex-builder-linux-dead)

  • @Abhinav
    You can use Adobe Air to create a desktop application like a Swing app.

    @Linux User
    I’m not sure what the status is. Can you ask on: http://bugs.adobe.com/jira/browse/FB-19053

    how does CS4 and FLEX/FLASHBUILDER4 go together ? I don’t want to mess up my CS4. Also, the same for FLEX3 ? can they run side by side ?

  • @dbmuse
    There shouldn’t be any conflict to running those applications together.

  • dbmuse

    installer refused my flex pro 3 serial number.
    Maybe because I started with 3 standard then upgraded to 3 pro.
    anyhow, online chat is busy, so I submitted a case and
    continue my install as an evaluation…
    if i didn’t have bad luck, i’d have no luck at all :)
    I’m still happy… been waiting for this puppy.
    now where is that CS5?

  • @dbmuse
    I think you need to give it a Flash Builder 4 serial number.

  • dbmuse

    yes… I did the upgrade (flex3pro to flashbuilder4pro),
    first I provide the ver 4 serial…
    then it claimed it could not find qualified product on my computer (mac)
    so I had to provide version 3 serial
    and I have 2 of those because I started at standard and upgraded..
    so I got that from flex 3 running on my computer
    it said it was 3 pro… so I am confident everything should be fine
    I copied it into the form
    but the installer says no…
    so the story picks up…
    I also notice I have a beta version of ver 4
    so something is off
    and incase someone else is in the same boat I thought I would give the details
    but I don’t mean to turn this into a support site…
    so I will say no more till I have the final solution

  • @dbmuse
    I think you need to uninstall FB 4 betas before you install FB 4 final. Try that and let me know if / when you find a resolution.

    the resolution required a phone call to support. After some review I was given a challenge response code that did the trick. If I ever reinstall, I will have to call support again… till then… I’m good.

    Hi James,

    The most annoying thing of all times happened with Flash Builder 4

    We just received our licence numbers last week and have been struggling to work the same way we did with Flex Builder 3.
    We setup a new project with a tomcat backed BlazeDS and when we used to launch our application by just clicking run, the URL was generated and our application was properly launched in a new browser window.

    It seems now that you can’t do that anymore. Or at least you have to change the URL generated by Flash Builder.
    What kind of joke is this ?

    I would love to be the one who missed something.

    Any idea ?

    Thanks from Paris, France

  • Farid

    Sorry for the harsh tone but it appears that you have to edit MANUALLY the URL to make this work.

    The migration process is not flawless.

    May I ask why Adobe didn’t bother to include in the eclipse package all the necessary stuff to we have to download manually AGAIN ? (mainly the WTP package)

    Anyways we’re looking forward to discover all the things we can build with it…
