FDS Required?

Hi -
I'm completing an evaluation of Flex, and I had a couple of
technical questions that I haven't been able to find answers to.
These questions are really to help me determine whether I need FDS
in addition to Flex, or if I can do without FDS.
In our deployment architecture, our Flex App will be deployed
via a webserver. I know that - without FDS - I can still invoke web
services that reside on this same webserver. The limitation is that
I cannot invoke web services on other webservers unless i deploy
FDS (mainly the proxy servlet).
Questions- without FDS, can I:
1. invoke HTTP services on the same webserver?
2. invoke remote objects on the same webserver?
Or do I need to have FDS installed to accomplish these tasks?
Thanks!

Hi Boris,
1. You can access http services or web services on another
server without
FDS - but there are a few caveats. First, you must be able to
place a crossdomain.xml
policy file on the webservices server and that policy file
must grant access
from the other domains that host your SWFs. However, if your
webservices
server uses HTTP status codes other than 200 for faults then
you cannot use
the Flash Player directly to communicate with these services
due to limitations
in the Firefox / NS plugin API that stop the player from
getting access to
the SOAP fault body in the response (this problem is avoided
by the FDS proxy
service).
Note that the crossdomain policy is required for accessing
remote objects
on remote servers too.
2. To access Remote Objects without FDS, you could use
ColdFusion, or you
could look for posts by customers who connect to one of
several open source
servers out there that can translate RemoteObject requests to
various types
of server application languages, like PHP, C# and Java.

Displaying images stored in SQL Server

Is there someway of displaying images stored within SQL
Server. Is FDS required? Prefer a method to display images without
using FDS; Web Service would be okay if that can work

I do that sort of thing using PHP and mySQL the binary part
of the image is stored in a BLOB field (Binary Large OBject) along
the rest of the information necessary for the http headers (e.g.
mime type, file name, file size) being staored in their own fields.
That info is then used to build the file using PHP. The PHP
file contains a mySQL query whos result is echoed with the
appropriate headers. The URL points at the PHP file rather than at
any saved image.
Here's the php:
<?
# display_imagebank_file.php
# Note: the ID is passed through the url e.g.
# this_files_name.php?id=1
# connect to mysql database
mysql_connect('HOST', 'USERNAME', 'PASSWORD');
mysql_select_db('DATABASE');
# run a query to get the file information
$query = mysql_query("SELECT FileName, MimeType, FileSize,
FileContents FROM blobTable WHERE ID='$id'");
# perform an error check
if(mysql_num_rows($query)==1){
$fileName = mysql_result($query,0,0);
$fileType = mysql_result($query,0,1);
$fileSize = mysql_result($query,0,2);
$fileContents = mysql_result($query,0,3);
header("Content-type: $fileType");
header("Content-length: $fileSize");
header("Content-Disposition: inline; filename=$fileName");
header("Content-Description: from imagebank");
header("Connection: close");
echo $fileContents;
}else{
$numRows = mysql_num_rows($query);
echo "File not found <br>";
echo $numRows;
echo " is the number of rows returned for id = ";
echo $ID;
?>
Hope that helps

EJB 3.0 integration in FDS, with Annotations

We have been working with the EJB 3.0 implementations and see
a lot of synergy between the new approach to enterprise Java with
this new specification, and would love to see FDS add an adaptor to
support it.
Our new entity/session beans have annotated relationships,
primary key information, and security regarding access to the
object and it's methods are specified already in the Java source.
Centralized management of this information where it is closest to
the source is highly productive.
With so much of the FDS configuration still sitting in static
XML files, we are required to maintain a redundant copy of all of
the annotation information separately. This adds pure overhead to
the development process, and it is challenging to keep the two in
sync when applications are enhanced.
We would like to see the FDS framework more tightly
integrated with the rest of the J2EE world, and through Java
introspection and annotations learn about the applications
available on the server side without custom config files.
The fill, assembler, and synchronization methods could simply
be a standard class interface to be implemented with methods to
override, or even annotated with flex annotations. Destinations
would no longer need to be hand-configured. The meta-data about row
identity would be read from the entity beans themselves. If a fill
method has parameters, read them from the function prototypes.
(The existing Flash remoting product seems to have the above
features. We enjoy the integration of Flash Remoting, and the
development workflow associated. The Flash client only needs the
JNDI name of the services, and once authenticated, access to any
function is possible without further action. FDS goes above and
beyond to provide several very interesting features, but is not
quite as intuitive when it comes to J2EE services.)
To tie this meta-information on the server back to the IDE
for visual design, using real server-side object properties and
methods, and session bean functions would close the loop on the
development cycle. This could also be accomplished within Eclipse
since the server side Java classes could easily be in the
classpath. The IDE could give the developer a hand in choosing and
referencing valid return object properties. An actionscript object
could even be generated if necessary from the entity bean's
properties...
Are any of these ideas in the works, or are there any
exisiting methods for accomplishing these efficiencies?

What is the first step of an abaper after getting the FDS

what is the first step of an abaper after getting the Functional Document ?what we have to do? how to analyze it , and how to face such interview questions on FDS TDS . any resource available.

Hi,
After getting the FDS , first understand the functionality of the requirment or take the help of the functional consultant and then start preparing TS ( TEchnical Specification) and do coding and get your doe reveirewed and prepare test cases and do testign in sand box and quality environment and after having got the confrimation that the requirment is met then port it to production.

Destination 'ColdFusionGateway' requires FlexClient support which was introduced in version 2.5....

Hi,
Hopefully someone might recognise this error...
Sadly it brings up only one result on google and that's a bit
vague as to how that person got out of thier hole... :(
I'm trying some very simple Flex Messaging with Flex Builder
2.0.1 and CF8 Standard (with LiveCycle 2.5.? built in)
But I get this error:
"Destination 'ColdFusionGateway' requires FlexClient support
which was introduced in version 2.5. Please recompile the client
application with an updated client framework."
I guess the '2.5' is referring to LiveCycle?
And I guess it's saying that the Flex compiler needs some
updated elements to compile with so it can work with LiveCycle ?
I think stepping into Flex for the first time just as FDS
became LiveCycle was not a good idea.
Strangely I (may have) narrowed it down to the gatewayid tag
in messaging-config.xml
eg:
<gatewayid>*</gatewayid>
OR <gatewayid>Flex2CF2</gatewayid>
Which has been there well before LiveCycle. BUT If I remove
this tag completely the error doesn't occur... then of course
messaging doesn't work without it. Ho hum
I can't see any DataServicesMessaging In/Outs using
cf-polling-amf... I'm having more luck with cf-rtmp - I can see the
'In' and 'Out' counters ticking away when i view my ColdFusion
Event Gateway Instance in the CF admin.
So polling-amf won't connect, whereas rtmp will. Neither
channel will 'subscribe' though.
I've got ColdFusion Extensions 0.5.155475 installed (don't
ask me how - it was a nightmare!) and working in Flex Builder 2.
I tried bringing the flex/libs over to flex builder from CF
as they were newer - no good
I updated Flex Builder with:
Flex 2.0.1 SDK with HotFix 3 from
http://labs.adobe.com/technologies/flex/sdk/flex2sdk.html
But nothing helps.

Thanx Mete, yeah i did...
but i solved it some other way... not entirely sure this was

it was fds.swc... possibly it was out of date or missing.

Using Flex 2 with/without FDS

I am presently designing a web architecture for a client, and
ideally I would like to employ a Flex2 UI on a Tomcat/Java web
server/server component framework (possibly Spring). I am trying to
get a good handle on the necessity of Flex Data Services (FDS) in
this architecture.
What am I really losing should I choose *not* to employ FDS,
and is rolling the entire server side with standard Java technology
fairly doable? Does anyone have any first-hand experience doing
this which they could share?
Given an expert-level server-side Java experience level, I
need to determine whether employing FDS is a necessity or not.
Thanks,
Brad

-Jason
Jason,
Thanks for the reply. How have you found the effort required
to manage the XML transmitted by the Flex 2 app to the server-side?
Has this effort been minimal, or have you found this minor? For the
most part, unless I can identify something major that FDS provides
to an org already versed in doing enterprise-class (J2EE) server
development, I'm not quite seeing the need for FDS. I understand
the description of FDS, and the synching / JMS capabilities, but
I'm not sure that this can't be fairly easily managed with standard
Java server objects (servlets, EJBs, or Spring POJOs). I don't want
to get into discussing licensing, but there needs to be
justification for such, especially at a per CPU rate, which is a
common need for everyone.
I'd love to hear from anyone who has employed FDS, or is
familiar with an org who has, who can speak specifically to the
value add experienced through use of this product.

FDS samples not working "send failed"

Hi all,
me again with another problem .....
I have installed FDS at the default location c:\fds2...
I am having problems running the sample apps that can be
accessed from the page :-
http://localhost:8700/samples/
The Integrated Flex Server is running in a cmd window as
required.
However, when I try to run the sample CRM app at
http://localhost:8700/samples/dataservice/crm/companyapp.mxml
(or any Data Service samples ) I get the initial screen showing
with the 2 panels BUT then get an error message "Send failed"
popup. When I say OK to this popup, I get not data returned.
I am sure it's a fairly easy problem to solve for you
talented folks.
Thanks in advance
Regards
Smak

Something is wrong with your installation because I've
istalled today the two versions because I want use Tomcat and the
CRM application works fine with JRun.
I have your problem with the J2EE installation wich gives me
a "Channel disconnected" and "send failed" message. I overcome this
problem running Integrated Flex Server before open CRM application
in tomcat. Now I have the two versions running without any problem

Is the Flex server required?

Does anyone know if I have to do anything special on the
server to be able to use flex? Can I just upload to my webserver
without making any modifications?

No to run compiled Flex SWF's you do not need a "Flex"
server. The exception is if you are using some of the Flex Data
Services (FDS) features.
Flex compiled SWF's are Flash files that require Flash Player
9.

FDS for server push + client to client

Just want to double check - if I was to create a chat like
app in Flex - where new messages are "pushed" to clients, this
would require FDS.

Using FDS would be the far easiest way to implement a chat
application.
Theoretically you could implement a chat application without
FDS by having each client poll the server for messages for new
messages for that client using HTTPService or WebService.
You can also do "poor man's data push" using a long-lasting
HTTP request - in this pattern each client posts an HTTP request
that it doesn't expect and immediate response to - when the server
has a message for the client is sends the response (perhaps a long
time later). In the client's event handler for the response the
client posts another request (so that the server has a means of
"pushing" data to the client). This is how Blackberry-style email
works in Windows Mobile (in the absence of a proper data push
protocol).
Sean
Neville's Introduction to the Flex Message Service has a good
example of how to write a chat application in FDS.

Is FDS the only way?

Hello every one, i am very new to this world of flex but i
have good concepts and working experience of AS. What i wanna know
is, do we have some other ways to connect to our server-side
languages like we have LoadVars in flash or we have to rely only on
FDS because most of my clients can't afford its hosting nor i can
do that effectively because i am not good in both JAVA and
coldfusion, rather i am a .Net developer. I know there is
HTTPService object but that only takes XML, what if if a want to
send some data in Non-Xml format like in query string or some other
way? please shed some lite on it in your expert opinions.
Thanks and regards!
Syed Mazhar Hasan

Hi Syed,
You're free to directly use LoadVars, URLLoader,
NetConnection, etc. in your Flex applications to interact with a
server. FDS functionality is built on top of these core Flash APIs
on the client, and they haven't gone away. So if you have simple
data access requirements and LoadVars works for you go ahead and
use it.
But take some time to read through the FDS docs to learn more
about the advanced functionality that it provides. When you get to
the point of managing sets of data that multiple clients may be
concurrently editing and viewing, it can really simplify and
empower your development.
Best,
Seth

501 Command "HELO" requires an argument

I repost this message, since I keep getting the same problem.
Keep getting the following error message while trying to run the code I've cut & pasted below on IBM AS400 machine. Can anybody help

if ((ex = mex.getNextException()) != null) {
ex.printStackTrace();
}

Helo.
I had the same problems and it can be solved this way :
Your code was :
// create some properties and get the default Session
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
Yo should add
props.put("mail.smtp.localhost", smtpServerName);
For example, you want to send an email using a smtp server called "toto" and you get the follwing error :
class javax.mail.MessagingException: 501 Syntax: HELO hostname
' just add :
props.put("mail.smtp.localhost", "toto");
And now it should works fine.
Hope it helps.

Configuring requirement : ordered item to absorb cost of free goods

Hello Friends,
I need to configure this in SAP SD.
The main item should accumulate the cost of the free goods.
I have set the cumulative indicator and deactivated pring for this item.
Do i still need to configure the stock value for the free goods as cost free item? Or is this step only applicable for
another scenario, like,
If I were to activate Pricing such that free goods is displayed as subitem and VPRS configured as cost and discount set to 100%
1. Set Item category to TANN using FREE usage AND
2. use condition type RL00 with requirement 55.
3. use pricing type B.
regards
Ravi
