When upgrading Flex Builder 2

Posted on March 24, 2007 | 4 comments

I found a step in the Adobe Flex 2 Installation (2.0.1 Update) that might when upgrading and trying to open existing projects.

Here is the step that I found useful:

Opening existing projects – The first time you open an existing Flex Builder project, you should refresh the workspace by using the -clean option. To do this, open a command window, navigate to the Flex Builder directory, and type FlexBuilder -clean -vmargs -Xmx512m.

    Yes, it’s a good technique.
    Also, remember that this can fix Flexbuilder/Flexbuilder Plugin when you have start-up errors.
    And .. .you can setup min and max for memmory in eclipse.ini/flexbuilder.ini in this way:

    Have a nice day.

    I am evaluating this software for purchase for our UI Development
    teams, 50+ people. I’m posting this question here because the FLEX
    forum is continually undergoing maintenance which is making it
    temporarily unavailable until 1:00pm PST. I’m on the east coast,
    and although I tried over several days to connect to this forum (all
    after 4pm EST), the FLEX forum is always unavailable.

    The question I am trying to get answered is regarding Flex Data
    Services. I’ve downloaded the files according to the instructions
    xj2ee .

    I placed the files in my webapps directory running on

    However, according to the instructions at:

    It appears I need to download additional applications in order to
    correctly use FDS (Java Transaction API (JTA), Java Management
    Extensions (JMX)). I have tried to download the JOTM 2.0.10.tgz

    without success. Once I try to unzip the
    file (I am running Windows XP Professional). I get the following

    “Error reading header after processing 0 entries.”

    I’ve tried to download three different versions of JOTM, and also
    tried saving the tar as a zip file. However, trying to open the
    WinZip file returns this error:

    “Cannot open file: it does not appear to be a valid archive. If you
    downloaded this file, try downloading the file again.”

    Has anyone been successful in downloading and opening the all
    important JOTM? If so, could you tell me where you got it, how you
    were able to open the files?

    Also, while I was reading the installation instructions for Tomcat

    it is pretty complicated for a non-Java programmer to
    understand. I asked one of our 6-year Veteran Java developers to
    help me with this and he said it was a pretty complicated process
    for someone w/o Java programming experience. But he did say that if
    I can’t download the JOTM, I won’t be able to do whatever it is that
    Flex Data Services is supposed to do. I say the latter because I am
    still in the “Getting Started” manual going through the last of the
    tutorials before I start reading “Using Flex”, so I’m not really
    sure what lessons I will be doing that require FDS to work correctly
    on my box.

    Was I wrong to think that Flex was supposed to be geared at Front-
    End Developers?

    To get up and running you can install FDS with the built-in JRun, probably not preferred for you specific development environment but nonetheless it could get you testing FDS (now LCDS).

    I’ll see if anyone has an answer for you on the Tomcat/missing packages side of things.

    Please download the excellent FDS tutorial that Christophe put together

    It comes with tomcat + FDS preconfigured, so you can get up in running in no time.
