[flexcoders] Re:Do I *REALLY* need Flex Data Services for WebServices?

[klotzw]

FDS is not required to use WebServices.  My application uses a J2EE 5
EJB 3 backend and defines a JAX-WS to create a set of WebService API's
to access my backend.  I then load my J2EE 5 beans and WebService into
the opensource Glassfish container project.

My Flex application is created using Cairngorm framework and the Flex
WebService interface.

Maybe you are just picking bad examples of what you are trying to do with 
parsing error messages, but best practice is only to ever return true/false 
from login methods to avoid leaking account details.

RE: [flexcoders] Re:Do I *REALLY* need Flex Data Services for WebServices?

[Ted Patrick]

Tom,

Your point is true. I was trying to state that many SOAP developers
build logic into SOAP Faults. Sure you can get a Boolean success/fail
but being able to interpret the fault result and call another WS method
with args is important. My login example wasn't clear and rather
simplistic but if the login response was that there was 'no user', you
could prompt the user to 'register', then 'login', then 'getUsers'. It
is the flexibility to interpret the SOAP Fault response that is a thorn
in the side of SOAP WS devs. I think Flex/Flash is missing a key lever
here and I am hell bent on getting this fixed.

It is a great point that we get a 'fault' error but that limits the
options for deep integration with web services.

My 2 cents!

Ahh.
We do
Call Login()
If result.success
Call GetUsers()
if result.success
...
else
display error
because you know GetUsers() will fail if the user is not logged in.

For our latest project, we're trialing a standardised way across all the

services of returning results (result:Bool,data:*).

RE: [flexcoders] Re:Do I *REALLY* need Flex Data Services for WebServices?

[Ted Patrick]

The real issue here is that in many cases the SOAP Faults drive business
logic. If you can get the 500 Faults, the soap enclosure can be
programmed to call other SOAP methods.

Here is a sample:

Call GetUsers()
500 Fault >> User not Logged in.
Call Login(username, password)
200 Success >> User logged in.
Call GetUsers()
200 Success >> Users Objects

This is the nature of SOA where faults can route into other business
logic and subsequent calls. We do get notification that a fault occurred
but we have no idea that the user was not logged in. Being able to get
the body of a 500 SOAP fault is critically important.

Which is fine, because your end users don't care what the error is, only
that 
it is broken.

RE: [flexcoders] Re:Do I *REALLY* need Flex Data Services for WebServices?

[Allen Riddle]

Before we made the switch to use FDS, we created a Java servlet filter
that would intercept all responses and change a 500 code to a 200, after
you do that, you will have access to the entire soap fault. This can be
done in .NET pretty easily as well if you're on the .NET platform.

In case of webservices, you can see some generic fault, but not the

Re: [flexcoders] Re:Do I *REALLY* need Flex Data Services for WebServices?

[Kelly Birr]

If you intercept the response from your web services and change the HTTP 
Status Code to 200 flex will receive and display the true SOAP 
Exception.  I am currently doing this in my .NET mid-tier applications. 
I'm not really sure how to do it on any other platform, but I must 
assume it's possible.
