If you’re using ColdFusion, the months web service is as follows:
months.cfc
<cfcomponent output="false">
<cffunction name="getMonths" access="remote" returntype="array" output="false">
<cfset var monthNames = ListToArray("January,February,March,April,May,June,July,August,September,October,November,December") />
<cfreturn monthNames />
</cffunction>
</cfcomponent>
I am calling a webservice using the same code as yours but it gives me following error:
RPC Fault faultString= “Unrecognized binding style ‘null’. Only
‘document’ and ‘rpc’ styles are supported.” faultCode=”Encoding Error”
faultDetail= “null”
I am not able to find out What is the reason for this error? Can you please help?
Could this be because the WSDL file I am using does not have style=”document” in . But is in the tag?
Any options to this or any other thing that I can do ?
Thanks in advance
In the above comment i tried to say.
The WSDL file I am using does not have style=”document” in soap:binding element. But is in operation tag. Could this be the reason why I am getting the above mentioned error?.
question :
flex dont let me define a operation name with a dot inside, what i should i do ?
help.
thnks
Thanks for the code.
I tried to create a flex application, which is calling a webservice. It runs fine locally. When put on the server, I am getting an error.
The fault string looks like
message faultCode:Channel.Security.Error
faultString:’Security error accessing url’
faultDetail:’Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL (http://myshec103077d:8080/Check/addint?wsdl)’
I tried putting crossdomain.xml in the root of the application server and I am able to access the cross domain file by typing
http://myshec103077d:8080/crossdomain.xml
The cross domain file which I had put is of the form
Still I am getting the same error, when I run the flex app on the server.
Can you please help me on this
Thanks,
Shameer.
Hello,
Im using flex and calling a .net webservice to fill a data grid clickin on a button but i get an error, hope you can help me! Here is my flex code, webservice is working in asp normally and returns an array of objects!
Hi again,
I forgot to say that error happens with WCF webservice. I tested with ASMX using the internet samples and all ran well!
As i cant find WCF samples for Flex could you tell me if Flex doesnt support WCF or something like that? Thanks!
Hi,
I am getting a query returned by the webservice. I am able to bind the returned query to gridview control. But how can I access the records returned one by one.
Eg. the query returned is name, age, salary. I want to get name in one variable, age in another and salary in third variable.
Akhilesh Srivastava,
I believe you’d have to loop over the result set and create the variables manually if you wanted them broken down by column (name/age/salary) instead of by rows.

Peter,
Thanks for your comment. Can you give me the code for this.

Need to proxy webservice ate proxy-config.xml
Nice example
Hi,
Is there any way I could know all avilable operations at runtime?
(means not specifiying “hardcoded” the operation name by myself)
Thanks!
Hi,
The example doesn’t work in flash player 10.
When I click on the button in the example above, I get an alert with “Fault” back from the webservice…
Any idea?
Laurens
