Dashboard appln using Flex+Java+MySQL+BlazeDS

I need to develop a Flex Dashboard application contaning Bar charts, pie charts, line charts which should display the data from MySql Database.
These charts should be refreshed every 5 minutes. I am comfortable with Java as backend instead of PHP. Do I need to use BlazeDS?
Can somebody suggest me how to develop this application or send me some sample working code?
Thanks.

For a Flex/Java/BlazeDS you can go to this blog http://coenraets.org/, there's a sample app named SalesBuilder that'll be very helpful for you I think. If you're looking for an example about the timer look at the docs what you need to do basically is add a timer setting the interval, add event listener when the timer gets the determined time and then call your services and so, then restart the timer.

Thanks for the link, I did search a little while before making the original post. I guess I wasn't searching for the right thing though.
The method I found listed in here seems to work in IE but not Firefox. It could just be a caching issue though I'm not real familiar with firefox and don't really know how to get it to forget that it's been to a page already.
I also updated the link listed above to ask about any changes in the last upgrade related to this.
This was related to caching in firefox and it worked fine after I logged out of my apex.oracle.com account and cleared the personal cache in firefox and then started over.

Email Registration with Flex/Java/MySql

Hi!
I'm developing a Flex/Java/BlazeDS web application. The DBMS I'm using is MySql.
I'd like to kwow how could I make the user to register by email.
They'll have to fill some fields like:
ID Number
First Name
Last Name
Address
E-mail Address
Then they will get an e-mail confirmation, they will click in a link existing in the e-mail, and they will exist in the database, and they will be able to make login, and other operations over the Web.
Thanks

How to use Flex builder with blazeds and JBoss

Following the instructions it is pretty easy to set up a project to work with the turnkey tomcat. However, I am having problems with JBoss because the app has to be deployed as a .war file. I can create a war file manually and depoly it no problem. How do I get flex builder to deploy to a war file? I want to be able to debug in flex builder and run at the click of a button.

Hi, I am trying to configure BlazeDS with JBOSS Application Server. I have downloaded BlazeDS binary version - blazeds_bin_3-0-0-544.zip from Adobe. But in the installation steps, it says that copy blazeds.war, samples.war and console.war into <JBOSS_HOME>/server/default/deploy folder. But in this zip, it contains only blazeds.war file only. I have copied it to <JBOSS_HOME>/server/default/deploy folder. I have restarted JBoss. I didn't get any error. But when i give http://localhost:8080/blazeds ... i am always getting "Page not found 404" error. Please help me, if you have detailed steps to configure BlazeDS on JBoss. Thanks for your time.

Using Flex Performance Profiler for Profiling Flex with Java Applications

Hi , I am planning to use Flex Profiler to profile my Application .
I have developed a sample Application using Flex MXML ,some ActionScript classes for Events and Cairngorm , Java , Oracle as database and Blazeds .
Can i use Flex Performance Profiler to Profile my Application . ?? I am asking this question as i ad read the below line from Adobe site and My Application includes java Methods
"You can use the profiler to profile ActionScript 3.0 applications " Can anybody please tell me What does this mean ?? and can i use the Flex Performnace Profiler . Please suggets me .

Thanks Karl for the prompt response .
I am making a call to a Java Method from my Action Script function , or getting data from Java Method into the ActionScript function .
So my question is , will the Flex Profiler will be applicable in this case as it internally calls Java Methods .

My pass of information for the people looking to use Flex with BlazeDS

I when approaching Flex Data Services (BlazeDS and Live Cycle
Data services ).. I noticed there was a huge gap of understanding.
So here are a few things I noticed which may help:
BlazeDS is a java based meaning it needs a Java program such
as Tomcat or JBoss to run..
By standard blazeDS comes with tomcat that will run on your
computer… And LCDS (live cycle data service) comes with JRun
(for local development use only)…
Remoting needs you to create a Java classes in order to pass
data, for example from a database… Now this side of things is
quite JAVA and therefore you’re probably going to need to do
a lot of Java programming.
However the messaging side of BlazeDS works well with
flex… If this is what you’re looking into, you should
concentrate on the produceer and consumer mxml objects:
<producer/>
<consumer/>
At first glance, these two seem stupidly simple and
un-powerful, but as you start to understand how to use them between
multiple applications, you will see how powerful they are.
And the config files...!
To get you pointed in the correct directions, review this
blog and focus on the tutorial section:
http://www.flexlive.net/?cat=6
Also remember that before live cycle, it was Flex Data
Services, try searching for some tutorials or learning materials on
that.
And also if your new to all this start with BlazeDS as it
seems more user friendly. Its just like using a restricted version
of LCDS. But works very much the same.!
Hope this helps, JC

Thanks prasoon.
I only had a few mins to write it, was in work lol.. What
helped you from that blurb, if you don't mind me asking?

Hi,
Need to use a scrollable resultset and depending on the need to have a stateful connection or a stateless connection you may need to query the table for every request(for stateless connection) and use the same result set for(stateful connection). and depending on the no of records in a page and the page no do some simple arithmetic and move the resultset. Hope this helps.

Hi
If you want to try out using ADOBE Flash Islands with WDJ, you would need to download SAP CE 7.1 EhP1 trial version, if not done so already.
The following link may help you in building the WDJ component with Flash Islands..
The specified item was not found.
If you donot want to develop the Flex project you can download the .swf file provided by the SAP mentors:

Using Flex/PHP to Display MYSQL data and Images

Does anyone have any good examples of using Flex 3 in conjunction with PHP to display data and images from a mysql database? I've searched a lot and it seems hard to find this combination. I have manged to create a login system using this which allows users to login via usernames and passwords that are stored in my mysql database (Grizzz helped me out a lot with this).
But I now want to create a product selection in the site with the categories down the left hand side and the products related to these categories displayed in the other panel once each of these products are clicked. The guy I'm making it for wants to be able to add and delete categories as well as add and delete products so obviously it needs to be done using php and mysql. I'm looking for something similar to the way the online shop is laid out in the following example:-
https://www.whitestonecheese.co.nz/Radshop/bin/Whitestone.html
Thanks for any suggestions.

To solve this problem I had to use labelFunction. The working line was this:
<mx:DataGridColumn headerText="Description" labelFunction="dataGrid_labelFunc" dataField="messageDetail"/>
The function looks like this:
private function dataGrid_labelFunc(item:XML, col:DataGridColumn):String {
var qN:QName = new QName(vm, col.dataField);
return item[qN].text();

Using Flex components in Java application

Hello,
I was learning Flex previously, and I thought I remembered reading somewhere that I can use Flex UI components in a Java application. For instance, I could use Flex for the UI, and Java for the backend. I can't find though the documentation for this. I read this last summer. I don't mean using Flex as a UI in a browser and Java on the server, but a Java application that runs on the client with a Flex UI. I thought what I needed was the flex compiler api, but I looked at the flex compiler api documentation and it isn't what I want.
Does anyone know what this "part" of Flex is that I am talking about, but can't remember?
Thanks,
Vance

No, thanks, but that wasn't what I was thinking of.
What I remember looking at was some library that allowed wrapping Flex UI componnts in Java Swing components. Then the Swing components could be used in the Java app. One main objective of my wrapping Flex in Java is to use flash.media.Video class to play flash video.

Using Flex Code in Flash

Hi everyone,
I really hope you can help me with this. Here's my
situation...
I've developed a flex application that connects to another
java application using "BlazeDS". It works great!! The reason why I
did this is because I'm developing (along with a Flash designer) a
website of a music band, and I use java to connect to a database
that has all the "gigs", news and subscribers to the website.
Everything works great in Flex, my problem is I'm not a
designer, I'm a developer. So I wanted to know if there's a way I
can just give my designer friend a code so he can use it in Flash
CS3?? (Like to send him objects containing the info. For example,
give him a concerts object that contains the date and the location
so he can build the datagrids for the concerts page in Flash)
I think there must be a way to use Flex libraries in CS3, or
maybe create some kind of Flex class that will work as a
"communication interface" between the database and the flash code,
I'm really not sure...
In other words, I need to know how can my designer friend use
(in Flash) what I've developed in Flex.
Please let me know if there's a way...
Just in case you need to know, I use Flex's Eclipse plug in
(it's easier for me this way cause I have java and flex in the same
place!)
Thanks!!!!!!

No need then to use the LocalConnection. In a listener
function (add a listener function for the complete event of the
SWFLoader) you can retrieve a reference to the loaded swf and get
the two values from the swf if they are public and on frame 1 of
the main timeline.
private function onSWFLoaded():void
//retrieve a reference to the loaded swf
var loadedSWF:MovieClip = logn.content as MovieClip;
<mx:SWFLoader autoLoad="true" id="logn" source="main.swf"
horizontalCenter="8" verticalCenter="185" height="364" width="588"
complete="onSWFLoaded()"></mx:SWFLoader>

'Public' Flex Java API licensing

Hi all,
I would like to use the MessageBroker and AsyncMessage classes from Flex Java API to publish messages to a Flex destination from Java classes.
The library with this API comes in the LiveCycle Data Services release but when i look at this API, it says clear is 'Public'.
How public is it? Can i use those classes freely for my production application? Is there any license restriction? Same license as for Live Cycle Services?
I need to know to decide what design i will use to connect or Flex client with our java server, so is really urgent.
Thanks,
Dani.

Looks like things have changed a bit since last week when I posted.
With the announcement yesterday of BlazeDS (scheduled for release 2008), it seems the libraries mentioned will be available under the LGPL v3, so I believe you may be able to redistribute them (unmodified and probably as a separate installer/archive) under the terms of the LGPL.
http://labs.adobe.com/technologies/blazeds/
It sounds like there will be some features not included in the OSS version of Data Services, but from reading the FAQ it seems that the messaging API you mentioned will be included in the LGPL licenced version.
