[flexcoders] Web Services: Nearing Wit's End
I've followed every single tutorial on consuming Web Services in Flex and not a single one works with anything other than simple demo web services available on the net. I've followed all the different methods documented and followed each and every step in detail. Now, I'm at the point that I am appealing for someone to take a look at my WSDL file and tell me what I am doing wrong. If you're interested in helping me out please let me know. Thanks. --Shibli
RE: [flexcoders] Question about Flex WebService
You may wish to specify that this is an SAP related question in the future as it will help those familiar with this subject identify the problem and offer solutions. You don't need FDS when consuming a Web Service. The error is saying that your WSDL is malformed. So I have some questions for you: 1) What version of R/3 are you using? 2) Are you sure ZGET_ALERT_NUMBER exists by that name? 3) Are you sure 8200 is your port? I would suggest you form your WSDL like this and give it a try: http://[SERVER]:[PORT]/sap/bc/soap/wsdl11?services=ZGET_ALERT_NUMBER Thanks --Shibli From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of snowedice Sent: Tuesday, March 06, 2007 12:30 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Question about Flex WebService Hi, Experts, please help me to see what is wrong here, thanks a lot!!

RE: [flexcoders] new to webservices in flex - need help! :)
Did you forget to post it in your email or have you completely left out
the columns of your datagrid? Please make sure you are properly
assigning the dataField properties for each column in your datagrid.

RE: [flexcoders] I want to write a tutorial
I second Arun's suggestion. There needs to be more examples of consuming Web Services in Flex.

[flexcoders] Questions Re: Web Services
Hey, guys, I don't know if any of you out there are SAP consultants, but
what I'm doing isn't anything out of the ordinary conceptually. I'm just
consuming a Web Service using one of SAP's standard BAPI's called
BAPI_SALESORDER_GETLIST.
When I debug it, I can see that everything goes fine and it returns the
data requested in the debugging console. However, nothing is binding in
my datagrid. I assume this is because I haven't set the properties
correctly according to the XML data received. Here's the XML (I've
replaced customer sensitive data with blah and removed most of the
columns for brevity):
?xml version=1.0 encoding=UTF-8?
SOAP-ENV:Envelope
xmlns:SOAP-ENV=http://schemas.xmlsoap.org/soap/envelope/;
xmlns:SOAP-ENC=http://schemas.xmlsoap.org/soap/encoding/;

Here's my Flex code to consume that:

P.S. I know that Visual Composer uses Flex, but I want to build my apps
in Flex Builder instead of VC.
Another weird thing that is happening is that on my laptop Adobe Flex 2
debugger console window shows me everything in progress. However, on my
desktop it juts says
[SWF] C:\Documents and Settings\Me\My Documents\Flex Builder
2\Lessons\bin\Services-debug.swf - 982,015 bytes after decompression
Any tips would be greatly appreciated. Thanks! --SBZ
