Getting Started with Flex 2

I played with Flex 2 beta 3 a while back, then got pulled off
into other things, and am now back to looking at Flex again and
thought I would go through the getting started lessons (on
http://livedocs.macromedia.com/flex/2/docs/wwhelp/wwhimpl/js/html/wwhelp.htm?href=00000138 .html).
I got to the second page and immediately got stuck.
Step 1 reads: "In a text editor, open the
data-management-config.xml file located in the WEB_INF/flex
directory of the samples web application. "
OK, where is this WEB_INF/flex directory located? And what is
the "samples web application" that is being referred to?
I THINK I found the right file, but in step 2 it says:
"Directly above the text <destination id="contact">, make
sure the following destination definition exists. "
The quoted text does not exist in the file, but the
definition it further explains to add already does exist.
So move on to the next page and it says to "...create an MXML
(text) file that contains the following text and save it as
lesson1.mxml in the DSLessons directory of the samples web
application." There's that samples web application reference again
- where IS that?
Oh, well THEN it has a link to a "Before you Begin" section -
maybe there are some answers in there! I click on that (why isn't
it in the index on the left?) and it takes me to a page suggesting
I do a few things. One of the things it says is, "Create a
DSLessons directory that is a subdirectory of the samples directory
of the samples web application. "
OK, well, dammit, now I'm frustrated! WHERE AND WHAT IS THE
SAMPLES DIRECTORY OF THE SAMPLES WEB APPLICATION?!
Is it wrong of me to assume that a "Getting Started with Flex
2" document would provide some foundational information that is not
based on assumptions of prior knowledge of the inner workings of
the very product I'm trying to get started with? This isn't even my
first time playing with Flex! In fact, I was hoping to find some
good step-by-step introductory material that would help some of my
coworkers learn a bit about it.
Where can I find some?

OK, apparently the primary source of my confusion here is
that some link I clicked on (I thought from a readme file, but I
can't find it again) took me to the aforementioned page in the
livedocs and did not display any corresponding topic open in the
left column, so I assumed I was on the first page of the getting
started section (especially since I was actively looking for a
getting started section when I wound up here). I have discovered a
more usable thread in the livedocs and am now a happier
camper.

Getting started with Flex ...

Hi All,
I've been looking a Flex over the last couple of weeks and have managed to setup a couple of basic projects that can read data from a mySQL database etc... However when it comes to understanding some of the more advanced frameworks and options to use with Flex it starts to get very overwhelming.
Does anyone have any pointers/suggestions for good material (online or books etc) to start with Flex. I come from an Oracle Forms development background and in terms of setting up an application with a connection to a database Oracle Forms seems to a lot simplier than building a Flex database application (although the functionality of Oracle Forms as a lot more limited than Flex/Flash).
I have taken a look at a the book Enterprise Development with Flex: Best Practices for RIA Developers (Adobe Dev Lib)http://www.amazon.com/Enterprise-Development-Flex-Practices-Developers/dp/059615416X/ref=s r_1_6?s=books&ie=UTF8&qid=1319581262&sr=1-6 by Yakov Fain, Victor Rasputnis and Anatole Tartakovsky (Mar 30, 2010), however the very first code example in the book appears to be dated and I'm having trouble getting it to work and finding the appropriately dated source files for the example project.
I have also taken a quick look at Adobe Flex 4.5 Fundamentals: Training from the Source by Michael Labriola and Jeff Tapper (Aug 5, 2011) which appears to be a bit more recent, however I am not sure how much is covered regarding database connections to databases like mySQL and Oracle.
Any suggestions on the best learning materials available would be really helpful. At the moment it feels like I need to be an expert in Flex, MXML, ActionScript, Java, Spring, Hibernate, AMF, Maven, BlazeDS etc etc just to be able to create a simple database centric application (aarrgghh).
Ideally I would love to be able to find a recent tutorial that goes through the building a relatively advanced Flex database centric application, that includes information about building a database based login/authentication system (without having to use PHP), and database controlled/stored main menu system and a system for modular sub tabs/screens/programs within a main application.
Regards,
Leigh.

Thanks everyone for the replies. I guess I'm a bit lazy when it comes to reading up on a technology I am not familiar with :-) . What makes things worse is the Oracle Forms Builder IDE is very highly coupled to the Oracle database and therefore there is no requirement to know or understand the language or technology under hood (other than PL/SQL), Oracle takes care of that within the IDE and the Forms Java Bean (deployed by default with a middleware installation of Oracle application server).
@dwaynie Started working through the Flex in a week video training yesterday. Its really good and probably the best place for me to start as it goes over a lot of the assumed knowledge regarding Flex, MXML and AS (stuff I have probably glossed over up until now)
@Mansuro noticed that spring has a dedicated page on the Flex/Flash plaform site so I'll probably look into this more down the track. I guess the thing I am little confused about is that there are many examples online that integrate Spring + Hibernate + Maven + Java etc etc, I guess each framework has different features that the others don't and therefore all can be used at once, or does each one offer a completely different service? More reading is required here I think.

Getting Started with Flex and Java RPC for Free?

Good Morning,
Please forgive me if this is the wrong place to post- I'm
just having trouble wrapping my head around what is and what isn't
available for free in the Adobe Flex world.
I've been working on an application for the last few months
using Open Laszlo (
http://www.openlaszlo.org/),
but I've been running into frustrations with their lack of
up-to-date documentation, and I've found it difficult to bring new
people into the project, since the set of users who know it is so
small.
While I do like that I can compile to DHTML, that's not
enough to hold me there.
I've been looking into Adobe Flex, and it seems like a good
alternative- I'm comfortable paying $500 for the IDE-
I use Eclipse currently, so having a plugin for it sounds
ideal. That said, when I look into ways to talk to a Java backend,
everything points to Flex Data services, which is now part of some
larger package costing tens of thousands of dollars.
I don't need advanced messages, or data synchronization, as
nice as it would be.. All I really need is the ability to call a
Java method, and get an object back, which I can then work with in
Flex.
I see the forum message that asks
"How
do I 'do' Flash for free?, but this only talks about RPC very
broadly. Given that the message is from over a year ago, I thought
it would be better form to start a new topic, than replying to it.
Can someone explain to me what components I'd need, both on
the client side and the server side?
Is there a set of manuals that explain how to do Flex RPC
from Java?
Can Flex compile to any versions of flash earlier than 9?
(Flash 6/7 is still in wide deployment)
Do I want to start using Flex 2, or Flex 3? Are the
components compatible? Will the F3 docs be ready?
Finally, where can I purchase the Charting components? The
ability to create charts such as
this
overcome a decent price barrier.
Thank you for any insight you can offer, and direction you
can provide.

Trouble Getting Started With Flex

I am trying to go through the tutorials that come with Flex
Builder 2 and cannot get any custom components to work. Projects
that have custom components defined in them compile OK but I get a

It works OK when I open the .swf file but fails when the .swf

Getting started with Flex - J2EE

Hello Folks,
In advance, I already want to thank all of you willing to take the time to read this, or even reply :)
Furthermore, I'm not 100% sure this is the correct location to ask these questions, but so far I've had a perfect experience concerning Questions I posted here :-)
Anyway, here's my current situation.
I've got Eclipse Europa (3.3) with the Flex 3 plugin.
I've got Tomcat 6 with the LiveCycle Data Services.
I've got some experience in coding Java classes, contacting Databases (I currently would like to use MySQL) and wiring it all with Spring/Toplink etc...
Anyway, I'm a bit lost when trying to do the following:
I want to create a webbased database management thingie. Easy mode. One table, 2 fields etc...
However, I'm completely lost at how to start.
I'm perfectly capable to create my Bean, Dao, DaoImpl and even a service layer above that which gives access to my Dao.
Other then that I'm, after some nice tutorials, capable in creating my FLEX-Gui to show it all.
What's the problem then?
Well, I have no idea what I need to do with my Java classes to make sure I can use them in my Flex App...
How do I need to create the war that needs to be deployed on my Tomcat?
Do I "NEED" to create JSP pages?
What is needed in my Service Layer to make it accessible by Flex?
What do I need to add in my Flex project to use that War? I need to point towards a 'war-location' when creating a J2EE based Flex application in Eclipse...
Anyway, I hope the explanation and the questions are clear enough and not too 'noob-like' :)
Lastly, I just want to add, that I've read chapter 5 in the "RIA with Adobe Flex and Java" book by Bruce Eckel, but he starts with a ready to use WAR so that doesn't help either :)
Any replies appreciated!
Regards,
P�eter

No. I didn't define it, because the lesson didn't ask me to.
I have however, since receiving your message, tried hard coding it,
but that doesn't work either. What is port 2037 anyway?

Getting started with Flex Builder, BlazeDS and Eclipse

Hi,
I'm a java developer looking at RIA for the first time. I'm really excited about BlazeDS and object remoting, but I can't get a working dev environment together. I'm assuming I should use Flex Builder for the client code, Eclipse Europa for the java webapp code, and deploy from both IDEs into the BlazeDS-equipped turnkey-Tomcat. I haven't found a tutorial explaining how to deploy a new webapp with this setup.
The turnkey-Tomcat sample app works fine. Trouble starts when I try to create a new project in Flex Builder. I don't understand the 'debug' deployment that Flex Builder does. Why are there 2 versions of my app, the regular and the debug versions? What is exactly the project structure that I'm supposed to have in Tomcat?
The specific error I encounter when trying to deploy a new Flex project is this:
[MessagingError message='Destination 'productService' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']
I do have a default channel configured for my environment in services-config:
And I do have a valid destination configured in remoting-config (I'm mostly interested in object remoting):
test.ProductService
Here's the client code:
What am I doing wrong? Where can I get help on these specific topics? Also, does anyone have an Ant build file that would automate this sort of deployment?
Thanks!

Hi Peter,<br />I don't have problems passing JavaBeans to Flex. For collections, I used DataGrid, it displayed my collection seamlessly, except I don't get column headers, just a column index number. For receiving a single JavaBean, I had a little more trouble, until I tried to display it with a DataGrid: it displayed a single row that represented my data, with each java property name used as a column header, and object attributes were displayed as 'object'. These 2 experiences led me to these conclusions:<br />- for the collection, Flex converted each element into an ordered list of attributes<br />- for the single bean, Flex converted it into a hierarchy of Maps of attributes<br /><br />I didn't create a Flex value object. Flex is doing it automatically,very much like in JavaScript/JSON: dynamic objects.<br /><br />Here's the remote object markup:<br /><br /><br /> <mx:RemoteObject id="myRemoteObject" destination="productService" <br /> fault="Alert.show(event.fault.faultString, 'Error');"><br /> <mx:method name="getProductsCount" result="setProductsCount(event)"><br /> <mx:arguments><br /> <arg1>{productSC}</arg1><br /> </mx:arguments><br /> </mx:method><br /> <mx:method name="getProducts"><br /> <br /> <mx:arguments><br /> <arg1>{productSC}</arg1><br /> <br /> <arg2>{pager.pageSize}</arg2><br /> <arg3>{pager.currentPage}</arg3><br /> </mx:arguments><br /> </mx:method><br /> <mx:method name="getProduct" result="goToView()"><br /> <br /> <mx:arguments><br /> <arg1>{selectedRecordId}</arg1><br /> </mx:arguments><br /> </mx:method><br /> </mx:RemoteObject><br /><br />And here's the dataGrid that displays the bean collection:<br /><br /><mx:DataGrid id="myDataGrid" <br /> dataProvider="{myRemoteObject.getProducts.lastResult}" <br /> change="selectRecord();"<br /> width="100%" height="100%" ><br /> </mx:DataGrid><br /><br />Let me know how it goes, I'd be glad to assist if I can.<br />Miguel

Getting started with flex and Eclipse 3.1?

Hi all,
Im a java Eclipse RCP developer and I wanted to work on some small apps using flex.
I have been searching around on the web for instructions on how to get everything set up, but most of them seem to skip a few steps.
I am using Eclipse ganymede (3.1), and have downloaded the flex sdk. Is there a plugin or something for flex that creates the proper perspectives in eclipse? Or what exactly do I need to do?
Also, I see that flex uses mxml, if I want to use flex and java as opposed to flex and php or coldfusion (the only examples I saw) is that possible? I guess Im slightly confused as to what exactly I am writing this app in... java? Actionscript? Php? ??
Basically my goal is this:
Use eclipse 3.1 (not flex builder)
Write an RIA that can also use AIR
Connect to a MySQL database on the backend
I have very little experience (or need) for J2EE, but maybe I should use it?
Can anyone point me to a good tutorial that will get me going to achieve my goal? Or tell me what exactly I need to install, and how to put it together?
Thank you!

You need Flex Builder plugin version.
Trial version here:

Getting started with the flex sdk

Hi,
I have been reading and reading this forum looking for an
answer to this question - have found lots of other great info :-)
I have installed the Flex Builder 2 trial and didn't get to
it before the trial ran out - got busy. So, now I'm down to the sdk
to get going with Flex. I have the sdk installed and the sample
apps have been compiled and they work. I have copied and pasted a
sample form and saved the file as .mxml. I have launched the
command line sdk. Now what do I do? I assume I type in something
and that something will include the file path to my mxml file that
I want compiled. What are the commands for the sdk so I can do
that.
I hope I'm on the right track :-)
Thanks!
jo

Change to the Flex bin directory and use mxmlc like this:
mxmlc path/to/my/App.mxml
This should create a SWF file that you can then run. If you
plan on posting the app somewhere, you'll probably want to create
an HTML wrapper. You can use the wrappers in the html-templates
directory.
For more info on using mxmlc, see the online help (type
"mxmlc -help list") or look in the Compilers chapter of the
Building and Deploying book. For more on using the wrappers, look
in the wrappers chapter of the same book.

Can not get example to work after following instructions given in "Getting Started with the NI LabVIEW C Generator" guide

We explored using sbRIO for our project, for different reasons we ended up going with a different embedded solution . We are currently evaluating the LabVIEW C Generator to convert some of the core analysis routines from LabVIEW to C so the team that will be creating the embedded solution don't have to re-implement them from scratch.
Before converting our code, I followed the instructions given in the "Getting Started with the NI LabVIEW C Generator" manual to create a static library created inCygwin using GNU Compiler Collection (GCC).
I managed to compile the code, but when I type "run GCD.exe" in the Cygwin console, I just see the window flash with no time to see if the result is correct or not. I modified the main.c cde to add a getchar(), but the window still just flashes and now I am left with the GCD process still running and have to kill it using Windows Task Manager.
Has anyone else got this example to run? I am sure I am missing an obvious setting or step, please help me.
More details below.
Thanks,
Fab
Here is a video showing the steps I followed
If you don't want/can't see the video. Here are some screenshots of what I have done so far:

C Function prototype definition:
I copied Makefile located at: C:\Program Files (x86)\National Instruments\LabVIEW 2011\examples\CGenerator\Tutorial\Cygwin
and replaced both Makefile and Makefile.cygwin in the directory where the C code was generated
I also copied main.c from the same location and replaced the one generated
Here is the snapshot of the results after executing "make GCD.exe"
Then to run it I just type
I see a window open and close really quickly and I never see the result. I have tried adding the getchar() line to the main.c file, but still I don't get to see the results.

Hi Kevin,
I hope you had a good Thanksgiving. I am attaching a zip file with the LabVIEW project, my build specification and my version of "Greatest Common Divisor.vi", which should be the same as the one that you have that ships with the LabVIEW C Generator, but just in case. I am also attaching a zip file with the C files generated by the LabVIEW C Generator.
You can also see the video I posted earlier with the steps I followed. I hope you are able to point out where I went wrong.

Getting started with an iBook G3?

Hey,
I just got an iBook G3 (500mhz, snow, airport, 10gb hd, upgraded ram), to compliment my iMac (G5 rev c) and I'm a little new.
It was used, I got it via trade.
Does anyone have some tips for me to get started with it ? I'm wanting to upgrade the HD to at least 20 GB, and to max out the ram. Any hints on that ?
Also, where can I get a new battery and charger ?
Also, what else should I know about it ?
It will mainly be used for writing (novel, fan-fics), surfing the web (wirelessly), and when I'm traveling...
Oh, it has OSX10.2 installed.

Hi, Josh. Welcome to Apple Discussions.
How much RAM is installed?
Does it have the original AirPort card installed? (You may want to install one, if not, to enable wireless access to the internet.)
Did the original system CD's and the OS X 10.2 software CD's come with it? If not, try to get the person you got it from to give them to you. You will need them if you intend to upgrade the hard drive (and for maintenance, even if you don't upgrade the hard drive).

Enough dual USB G3 iBooks suffered from a logic board problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Check out the FAQ page and be aware of how this logic board problem manifests itself.
It has been suggested that you can minimize the chance of a logic board failure of this sort by never picking it up by the front left corner alone. Pick it up with both hands or in the center under the trackpad.
It's also a good idea not to close it any more often than you need to in order to minimize the chance of the backlight cable (and other cables and wires) becoming pinched in the hinge or broken. When you have some time, check out the Discussion thread in the Displays Forum entitled 90 degrees and black out!!!!
Information on using the battery to maximize both life and lifespan can be found here.

Java Applet HelloWorld "Getting Started With Applets" example not working

Hi there,
It's been ages since I ran my Linux CentOS boot of Linux but I am going through the official oracle java applet tutorials, just every time I try and run the "Hello World" applet in Firefox 17.0.3 and I am running the Iced Tea thing for java applets.
Every time I try and run the example from the following code:
import javax.swing.JApplet;
import javax.swing.SwingUtilities;
import javax.swing.JLabel;
public class HelloWorld extends JApplet
// called when the user enters the html page:
public void init() // keep apps within the init() function very small as per the http://docs.oracle.com/javase/tutorial/deployment/applet/appletMethods.html
    try{
      SwingUtilities.invokeAndWait(new Runnable()
        public void run()
       JLabel myLabel = new JLabel("Hello World");
       add(myLabel);
        } // end running the application
      }); //end of swing invokeand wait
    } catch (Exception error){ // end user running the app in page
       // System.err.println("GUI didn't work on initial run");
}It keeps bringing up the error "Start: Applet not initialized" I did google that basic error and from what I found I should consult the JavaConsole, I know the console was removed from the Firefox menu quite a while ago. So went to find a way of loading it using the IcedTea one but it keeps bringing up a load of errors in even trying to run that.
Is there anyway of sorting this out? I mean I have even tried installing the one on the oracle website, the plain JDK but nothing seems to work.
Is there anyone that can help me get applets working? I was even going to go as far as to reinstall my distro but I want to avoid that as much as possible.
Thanks and I look forward to any replies,
Jeremy.

in the Getting Started with Java DB tutorial they
tell u how to set ur "DERBY_HOME" (what is that?).
once i press enter after typing this command:
set DERBY_HOME=D:\Java\Java
Phonebook\javadb in my command prompt do i get
any message or does it just go to the next line?type env or set or whatever in the command line to see what your environment variables are set to
they also tell u how to set ur "JAVA_HOME" (what is
that?). The Java installation you want to use
in their example they give u this: set
JAVA_HOME=C:\Program Files\Java\j2se1.4.2_05but in my java folder i have jdk1.6.0 and jre1.6.0
but no j2se1.4.2_05, so which 1 must i choose?It's up to you. I'd go with 1.6
also once ive done this: set
DERBY_HOME=D:\Java\Java Phonebook\javadb this
set JAVA_HOME=D:\Program
Files\Java\jre1.6.0 and this set
PATH=%DERBY_HOME%\bin;%PATH% and then type
sysinfo to verify that the variables were set
correctly i get these errors: 'D:\Java\Java' is
not recognized as an internal or external command,
operable program or batch file and '""'
is not recognized as an internal or external command,
operable program or batch file any help would
really be appreciated because this is really killing
me!you need to set your path variable - so something like:
set PATH=C:\Program Files\Java\j2se1.4.2_05\bin

Hi Christoph and WarriorAnt,
Thank you both for the replies.
I don't know anything about GarageBand because I've never used it. I've never used any music software before, (other than iTunes, Ha!)
I don't have GarageBand on my Mac because it wasn't stock on the old Powerbook G4, so I would have to buy it. I'm happy to do that if I can figure out that it does what I want ... but I'm overwhelmed by the info at Apple's site. Too much for a beginner like me. Even the wikipedia.com entry for GB uses too many terms I don't know, so I'm easily lost.
I just want to be able to set up drum loops and play along with them. The main thing is that I'm able to use third party loops. There are so many really amazing loop products out there ... jungle drums, acoustic jazz drums, lounge, etc. I don't want to get caught up in anything proprietary (like Band-In-A-Box) because the selection is limited. I'm sure GarageBands loops are great, but I want access to all these other third party loops as well ... loops that were not specifically made for GarageBand.
Will GarageBand let me drop in any and all drum loops from these other companies?
And does GarageBand work like a basic sequencer, where I can program up an intro, X number of measures of a loop, then a turnaround, then a variation loop, then an ending, etc?
I know the high-end stuff like Native Instruments Kontakt does this, but unfortunately it also does a kazillion other professional-level things I will never need and don't want to pay for (and which make the software more complex and daunting).
Thank you again, both of you, for responding and helping me with this project.
Just a little more advice on those two questions would really go a long way.

Getting Started with FCE - Problems with my imported files

Hi,
I'm trying to get started with Final Cut Express, but I'm experiencing lots of problems when I import my project from iMovie.
My project contains video, which I imported into iMovie at 960 x 540. It also contains some keynote animations, which I exported from Keynote as quicktime files.
When I export my files to FCE, I instantly get problems.
1) When I add the imported file to the sequence, I get an "Attention the clip does not match the sequence's setting or any of your sequence settings" error.
2) Whether I choose to translate my settings or not, I try to play the video in the timeline, but there is a continuous beeping sound, no audio from my video and when it hits the keynote animations, it just says "unrendered" or "media offline".
Please can you offer any advice on how I can get started with FCE more successfully.
Thanks!

Hi(Bonjour)!
(please specify iMovie and FCE version)
Well, your sequence settings in FCE should be DV-PAL 48 Khz.
Create a new sequence.
From iMovie and Keynote, export your movie with quicktime conversion andd select DV-PAL 48 kHz (*And Not* DV Stream...). This material should play without rendering because his format and codec match the sequence's codec.
Import your files and everything should be OK.
Michel Boissonneault
The audio should be AIFF 48 kHz 16 bit linear PCM
