Flash Builder 4 connect to Data/Service

I am attempting to connect Flash Builder projects to a custom AMF server using the connect to Data/Service tool.
I am able to successfully connect to the server and create a service connection. Flash Builder creates a service but
does not recognize any operations. I believe this is because the server is not responding correctly to the Flex Introspect request.
I am sending an AMF package back to Flash that looks like this:
\c@\c@\c@\c@\c@\cA\c@\c@\c@\cB/0ÿÿÿÿ\cJ\c@\c@\c@\cA\cB\c@\cIgetPeople or
in HEX 00 00 00 00 00 01 00 00 00 02 FF FF FF FF 0A 00 00 00 01 02 00 09 "getPeople"
Can someone please provide any documentation on the format required for this response?
Thanks in advance

Flash Builder 4 and Blaze Data Services wizard

Hello,
My project uses BlazeDS for backend and Flex for frontend.
I use Data Services wizard to auto generate the valueObjects from the corresponding Java classes.
But the generated code does not seem to implement object inheritance. The valueObjects only inherit from their own _Super* classes.
Example
Java objects
Circle extends Shape
Generated actionscript objects
Circle extends _Super_Circle extends EventDispatcher
Shape extends _Super_Shape extends EventDispatcher
Doesn't Flash Builder Data wizards support this feature or am i missing something?
Thank you
Filaretos Postekoglou

Hi,
It should work fine. Can you please share the exact version of the LCDS. Also please let us know the service types and channel types you are using in your application.

Flash Builder 4 and PHP Data/Services for beginners

Hello,
I'm new here, so I do not know if I posted my doubts in the right place.
without much la la la go straight to the point.
I am developing an application in flex / mysql / php / zend DataWizard and used the flex to create the data service.
populei my dropdown with the desired data (cities) and populei my datagrid with their respective data (customer master), so far so good. That's when I came across a difficulty which already makes two weeks and try to solve anything. the little knowledge I have in programming know it's something silly, but I can not solve.
Difficulty: I select a city in my dropdown and display all my customers registered in the same city in my datagrid. simple! I found some tutorials on the net talking about it, did exactly what her boss but unfortunately got no success (not populates the datagrid), may be doing algor be unable to realize. so it follows my code so they can help me. grateful!!
FLEX CODE
/ / Populating DropDownList City
protected function ddl_cidade_cadastro_solutions_creationCompleteHandler(event:FlexEvent):void
getAllMunicipioResult.token = municipioService.getAllMunicipio();
//Populating DataGrid
protected function ddl_cidade_cadastro_solutions_changeHandler(event:IndexChangeEvent):void
txt_recebe_cidade.text = ddl_cidade_cadastro_solutions.selectedItem.Cidade_PJ;
getAllEmpresasResult.token = empresasService.getAllEmpresas(ddl_cidade_cadastro_solutions.selectedItem.Cidade_PJ);
PHP CODE
public function getAllEmpresas($q) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE 'Cod_Cidade_PJ' LIKE '%$q%'");
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);

Hi,
The first issue will be the pathing differences between wamp/mamp/xampp, some use www as root others htdoc you need to setup the php services on your local machine rather than importing a project.
The created services will have a connection array declared at the top of the code that points to the mysql server, in the project default debug folder you will have the config file that has the zend and webserver path
top of service file
============
var $username = "root";
var $password = "";
var $server = "localhost";
var $port = "3306";
var $databasename = "zend";
var $tablename = "clients";
var $connection;
amfconfig.ini
=========
[zend]
;set the absolute location path of webroot directory, example:
;Windows: C:\apache\www
;MAC/UNIX: /user/apache/www
webroot =C:/wamp/www
;set the absolute location path of zend installation directory, example:
;Windows: C:\apache\PHPFrameworks\ZendFramework\library
;MAC/UNIX: /user/apache/PHPFrameworks/ZendFramework/library
;zend_path =
[zendamf]
amf.production = false
amf.directories[]=Zender-debug/services
In your main project folder you have a .model folder the file there is an *.fml file that contains your channel endpoints etc.

How to create php login in flash builder 4 using php data service

I have seen the tutorials for creating a php login authentication using HTTP service in flex 3 It uses genrating xml and reading it . But i want to know how to do that with the help of php services in FB4 . I'm a newbie so please any kind of help would be appriciated as 'm not able to get any flex developer in nagpur ....

Connect to PHP in FB4 is used when you have a PHP Class and you want to use that in FB, for example Employee.php and it has a Employee class and various methods in that like create, update, get, delete.
However, if you have exposed your functionality in PHP as a HTTP URL (i.e. it is not a class), then you should be using HTTPService from the data menu.
So if your file is login.php and is accessible as a URL, then using the HTTPService and enter the URL.
Does this help?

Running "Flex test drive" - Got error while attempting to connect to data service

Hi,
I'm a Flex / Flash builder beginner. I downloaded the 60 days evaluation, and started to run the "Flex test drive" :
http://www.adobe.com/devnet/flex/testdrive.html
My configuration :
XP SP3 PRO french edition
Tomcat 6.0
My local Eclipse :eclipse-jee-helios-SR2-win32 (but also got the issue on the Flash Builder Eclipse, which version is 3.4.0 (Generation ID M20090211-1700)
Flash Builder 4 with Eclipse plug-in
All on same PC
The Test Drive proposes examples in three technologies : Cold Fusion, PHP and Java. I'm doing the Java examples.
Installation of Flash Builder, as well as step 1 of the Test Drive (Build the user interface) went fine. I could run the project, which at the end of step 1 correctly displayed the UI in my browser.
Only one problem, I don't know if it is relevant for the rest of this post : I first got an error, saying that ports 8080, 8005 and 8009, requested by Tomcat, where used. After a short Google search, I fixed it by changing these ports to 8081, 8006, and 8010, in the Tomcat 6.0\conf\server.xml file.
The Test drive second step is "Connect to data". I found some discrepancies between the Test Drive doc, and what is displayed in Flash Builder. The Test Drive says :
"Use the Data menu and the Service Wizard to create a service for your application server. For ColdFusion and Java, specify the service file you put on your application server earlier (see Figure 9 for a PHP example). For Java, select the No password required check box, select the employeeService destination, and change the service package to services.employeeservice."
--> But there is no "No password required check box".
Also, when running the "Connect to data/service..." wizard, it was not at first completely clear what to choose. The proposed choices were :
BlazeDS
ColdFusion
HTTP
LCDS
PHP
Web Service
XML
Since all others choices, when tried, declared to be unconsistent with my project's server type, I finally selected "Web Service".
In the next wizard's form, according to the Test Drive indications, I specified the URI of my EmployeeService class : C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\testdrive\WEB-INF\classes\services\EmployeeService.class
That defined correctly the other fields.
But when pressing the "Next >" button, Flash Builder issued the following error message :
English translation : Unable to extract operations and entities from specified WSDL. Reason : an error occured while instrospecting the service.
And the full error text is :
An error occured while instrospecting the service. WSDLException: faultCode=PARSER_ERROR: Problem parsing 'file:/C:/Program%20Files/Apache%20Software%20Foundation/Tomcat%206.0/webapps/testdrive/W EB-INF/classes/services/EmployeeService.class'.: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 2 of 2-byte UTF-8 sequence.
It is usually relatively easy to find fixes through Google searches, but this time, it didn't work. So here I am, expecting a bunch of wise answers from all the nice Flex / FB gurus that I'm sure haunt this forum .
Thanks and best regards.
Marc.

For those who would have the same problem, here is how I could eventually fix it.
Since the Flex Test Drive is sometimes out of sync with flash builder 4, I recreated a project using other help pages on Adobe site :
Entry point :
http://help.adobe.com/en_US/Flex/4.0/AccessingData/WSbde04e3d3e6474c4-668f02f4120d422cf08- 7ffd.html
As suggested, I used the New Project wizard to create a new project, with :
Application server type : J2EE
Check the radio button "Use remote object access service : BlazeDS"
Then, as indicated in following pages (section "Accessing BlazeDS")... :
file:///C:/Mes%20documents%20C/Commun/Developpement/Documentation/HT-Tracks/AccessingData/ help.adobe.com/en_US/Flex/4.0/AccessingData/WSbde04e3d3e6474c4-668f02f4120d422cf08-7ffe.ht ml#WSbde04e3d3e6474c4-19a3f0e0122be55e1b7-8000
...I selected the "Data / Connect to Data/Services..." menu option, which started the Data/service connection wizard.
There, I selected a BlazeDS (and not Web Services) service type, and everything went fine.
Suggestion to adobe staff : maybe it would be useful to update the Flex Test Drive to reflect Flash Builder 4 ?
Very nice product anyway, so far, congratulations...
Rgds
Marc.

Impossible to use "Connect to Data/Service" with BlazeDS

Hi everybody, I'm work on FB4 since 3 weeks, but I have big problem to use "Connect to Data/Service" with BlazeDS. each time I try to use it, it's the same question " You must define a BlazeDS server" and when I define the BlazeDS server and .war, I have the question again... You must define a BlazeDS server
I work on Mac OsX Leopard and his java 6.
Thanks for your help

Hi,
Thanks for your feedback
Can you please tell us which version of Flash Builder4 and BlazeDS you are using.?
Also, can you try the same workflow by using the turnkey version of BlazeDS(4.0.0.11428) with Flash Builder BETA2 build.
Please let us know the outcome.
Thanks,

Problem connecting to Data/Service outside web root

I'm new to Flash Builder (4.5). I work in an environment where developers have full access to a specified folder and subfolders on a Windows box running IIS 7 and ColdFusion 9.
So the path to the services-config.xml looks like this (server and folder names have been changed, but the structure is the same):
\\servername\flex$
Path to coldfusion root looks like this
\\servername\coldfusion9$
The developers don't have write access to those areas. What we have is
\\servername\webteam$\webcontent\app1
\\servername\webteam$\webcontent\app2
And so on
Then our server admin sets up virtual servers so that our urls look like http://app1.ourdomain.co, app2.ourdomain.com, etc.
I set up a project specifying ColdFusion as the server technology and using the above paths and everything works
I've run set up a couple Hello World tests using <mx:RemoteObject destination="ColdFusion" source="app1.flextest"></mx:RemoteObject> and everything works as expected. (No database connections, just a function that returns a string)
The problem is when I try to exploit the magic of Flash Builder and use the Connect to Data Service feature to write my queries for me : )
I select ColdFusion
In the CFC location I enter
\\servername \webteam$\webcontent\app1\cpa\flextest.cfc
Which is the same working cfc I connected to manually in my Hello World test. Flash Builder automatically populates the Service Name, Service Package, and Data Type Packages and I click next. I enter my RDS password and I then get this error:
The CFC file is invalid. Possible causes can be found by accessing: http://app1.ourdomain.com//CFIDE/componentutils/cfcexplorer.cfc?method=getCFCMetaData&name =flextest&path=%2Fwebcontent%2Fapp1%2Fflextest.cfc
Copying and pasting the url into my browser I get this error:
The value returned from the getCFCMetaData function is not of type struct.
HOWEVER, if I modify the url and remove "%2Fwebcontent%2Fapp1%" I get a response:
E:\webteam\webcontent\app1\flextest.cfcE:\ColdFusion9\wwwroot\WEB-INF\cftags\component.cfc WEB-INF.cftags.componentWEB-INF.cftags.componentcomponentcpa.flextestcpa.flextestcomponent remoteflexteststring
So I just need to tell Flash Builder to shorten the path and not add "/webcontent/app1" How?
Sorry it took so long to explain. I've been googling for days and can't find anything. I'm sure there must be other users who develop on servers outside the root path of their web server, right?
P.S. I tried mapping drives but that didn't help
Thanks,
Ron

Hi ,
Check if the database server is up and running.The console will have two root nodes .R they both in green?
Try connecting and entering into the database externally.
Generally if the DB instance is not running , this error would occur.

Flash Builder 4 Beta 2 ---- Data Management Problem

Flash Builder 4 Beta 2 ---- Data Management Problem
I have a simple datagrid, a PHP service and a MySQL database. When I run the code I get multiple(7) records returned to the datagrid. Once I enable Data Management and run the exact same code, I only get 1 record returned.
Is there a setting in Data Management that affects the number of records returned?

Hello,
Data Mangement expects unique values for id property.This issue may occur when you select 'Identity' property in Data Mangement wizard which is not unique in the Table.For eg:, you have selected 'name' field as identity property. And your MySQL database table has multiple rows with identical values for 'name' column.
Can you verify if you have similar setup?
Thanks,

Solution Manager connection in Data Services

Hi,
When trying to make a data store connection in Data Services to a Solution Manager system I get an error that there is no connection or my credential are wrong.
I can ping the system so there is a connection.
I can log in to the Solution Manager system via the GUI so the credentials are ok.
So far i have found out that the Data Store connection cannot connect to Solution Manager because it per default tries to connect to port number 3200 while the Solution Manager system default has port number 3300.
But i can't change / select port number in the Data Services data store connection. So what do i do?

Connection between data services and BWA

Hi,
I want to make a connection between Data Services 3.2 and BWA. Since we use RFC connection in between in order to have them talk with eachother but i wonder if there is any documentation that describes the RFC connection and configuration required particularly in this scenario. I have gone through the documentation that explains RFC connection between Data Services and BW and what configuration we have to do, so i wonder if there are any functions we have to export to BWA from Data Services like we do in case of BW connection to Data Services or some specific configuration we have to do. If someone help who has done connection between Data Services and BWA can help or if somebody can provide documentaton on it.

Hi,

Connect Flash Builder 4 to remote PHP service

Hello i have seen some videos that explained how easy is connect Data/Services to local PHP server, and then extract the methods instantly. Also binding it to a datagrid, and everything was with wizard, easy and fast.
I would like to do the same but my problem is that i always work with remote PHP (not localhost), and i don't know how to connect flash builder 4 to my remote PHP class.
PS: I know how to do it manyally, but then i would not use the power of the wizards.
¿Is there any solution?
thanks

Would you mind giving me an example?:
the server path is /httpdocs/
and my website is for example: http://www.smspubli.com
I though that maybe the solution is on mount a virtual folder that connects to my httpdocs via FTP (problem is that in mac os it lets you create virtual folders but only in read mode)...
Please help me, there is no solution in all internet and then only way to use the power of flash builder 4 is connecting to localhost...

SAP R3 Connection in Data Services - Configuration is

Dear all,
We are having an error when going through the steps in the configuration of BusinessObjects Data Services 3.2 with R3. The error is in the SAP R3 server.
Herewith the steps in regular font (based on the SAP BusinessObjects guide) and our output results in bold. If you can take a look on it, it will be great for us.
To install provided functions using the CTS system:
1.     Copy the provided transport files to the appropriate directories on the SAP server.
Installing Functions on the SAP Server Installing the functions using CTS
Note:
In these steps, 900XXX.SXX is a variable. To substitute the correct file name for the current release, see the readme.txt file in the ...\DataServices\admin\R3_Functions\transport directory.
-     Copy R900XXX.SXX to the /usr/sap/trans/data directory.
-     Copy K900XXX.SXX to the /usr/sap/trans/cofiles directory.
As we have R3 connection we have moved the R63 file. Complete name of the files are:
-     R900086.R63
-     K900086.R63
2.     Log on to the SAP server and run the transaction /nSE37 to determine if function group ZAW0 already exists. The CTS system will install the Data Services functions into a single function group ZAW0 that it automatically creates on the SAP server if it does not already exist.
-     If function group ZAW0 exists and contains previously installed Data Services functions, add an unconditional mode 2 option (parameter U2) to the tp import command described in step 4 below (tpimport S<xx>K900<xxx> <SID> U2).
-     If function group ZAW0 exists and is used for another purpose, modify the transport file to use a different function group (such as ZAW1) to install the Data Services functions. Make sure the function group you use does not already exist in your system.
-     If you are installing the transport files on a Unicode-enabled SAP server, manually create the function group ZAW0 with the Unicode attribute set.
In our case we have found there is already a ZAW0 created -> nothing to do in this step
3.     From a command window, run the following transport command:
-     tp addtobuffer S<xx>K900<xxx> <SID>
(where SID is the SAP system ID)
You receive the response:
This is tp version <SAP TP and SAP versions> for <database type> database.
Addtobuffer successful for S<xx>K900<xxx> tp finished with a return code: 0 meaning:
Everything OK
This is the command we have run and the error retrieve
The SID is NDV.
C:\tp addtobuffer R63k900086 NDV
This is tp version 372.04.57 (release 700, unicode enabled)
E-TPSETTINGS could not be opened.
EXIT
Error in TPSETTINGS: transdir not set.
tp returncode summary:
TOOLS: Highest return code of single steps was: 0
ERRORS: Highest tp internal error was: 0208
tp finished with return code: 208
meaning:
error in transportprofil (param missing, unknown, ....)
We have modified the statement with different names for the R63 file, but we didnu2019t success. We are retrieving same error.
We also have applied the command in the following link:
http://sap.ittoolbox.com/groups/technical-functional/sap-basis/etpsettings-could-not-be-opened-875506
and retrieve another error. The following step would be doing the u201CSAPEVTPATHu201D downloading, but, we are not sure if this would fix the issue or if the issue is related to something else.
4.     Run the next transport command:
tp import S<xx>K900<xxx> <SID>
(where SID is the SAP System ID)
We couldnu2019t reach this point, as we are having an error in the command below.
Thanks for your help on this!

Odbc connectivity with Data services 4.2

Hi guys
i have very general question to ask...
presently i have dataflow which has one source table connects to query transform and further query transform connects with target table.. query transform has no filter, no order, no group by ... it is simple select * from source table ......... company where the source tables resides have given us their odbc driver to connect and extract same data... but it takes very long time to copy at our end.. i admit that data is more than 100 million (takes more than 4 hrs) records.. but could you please help me to debug what can be done to increase the performance and how can i check why it takes very long time...
ODBC connection set up in administrative tools->ODBC application.. is there any other way to set up the odbc....
when i run same query on the tool provided by them to connect with LIVE system.. it takes half of the time taken by data services to copy..
I have tried changing the dataflow properties between in-memory/ pageable with degree of parallelism.
what can i check on my end if anything wrong going at my end... before i tell anything to source company to see...
I would be very greatful if anyone can help me to understand same.

Hi,
If your database is SQL server, install a SQL native client on the DS machine to connect to the DB. You don't need a ODBC for connection of DS with DB.
Check this, assuming your DB is SQL.

Mobile development using Adobe Flex 4.5 SDK and Flash Builder 4.5 for Data Visualization

Hi,
I am currently looking at the feasibility of building Data Visualization chart/graph in Android mobile phones. I would like to enquire if the mentioned subject comes with the Data Visualization components as seen in the Tour De Flex.
Cheers!

If you're using components specific to the Flex 4.6 release, then it would be a natural assumption that design view will not work. If you're having this issue while using components that are not unique to Flex 4.6, then I don't have an answer. On a good note, design view is completely useless anyway. It's much faster to type than to drag stuff around with your mouse needlessly.
