Hi Telmo,
The client code looks ok. I understand you generated ExampleService
with Flex Builder import WSDL feature. I've reproduced your case and
got the same error.
I also created a simple client ant got a different error:
[SWF] Users:mykola:Documents:Flex Builder
3:SampleClient2:bin-debug:SampleClient2.swf - 973,882 bytes after
decompression
Error: Unrecognized binding style ''. Only 'document' and 'rpc' styles
are supported., details: null, trace: [RPC Fault
faultString="Unrecognized binding style ''. Only 'document' and 'rpc'
styles are supported." faultCode="EncodingError" faultDetail="null"]
at
mx.rpc.soap::Operation/http://www.adobe.com/2006/flex/mx/internal::invokePendingCall()[E:\dev\flex_3_beta3\sdk\frameworks\projects\rpc\src\mx\rpc\soap\Operation.as:713]
I would check the web service. Flex complains about SOAP binding
style. It should be JAX-RPC Encoded or Document Literal.
Here is my client
<pre>
import mx.rpc.events.FaultEvent;
import mx.rpc.soap.WebService;
import mx.rpc.events.ResultEvent;
import com.marcocova.ExampleService;
import com.marcocova.GetPeopleByFirstLastNameResultEvent;
public function getResults():void{
var ws:WebService = new WebService();
var wsdl:String = "http://ws.marcocova.com/SOAP/af4.php?wsdl";;
ws.addEventListener(FaultEvent.FAULT, faultHandler);
ws.getPeopleByFirstLastName.addEventListener(ResultEvent.RESULT,
processResults);
ws.loadWSDL(wsdl);
ws.getPeopleByFirstLastName("*", "*");
// var ws:ExampleService = new ExampleService();
// ws.addExampleServiceFaultEventListener(faultHandler);
// ws.addgetPeopleByFirstLastNameEventListener(processResults);
// ws.getPeopleByFirstLastName("*", "*");
}
public function
processResults(res:GetPeopleByFirstLastNameResultEvent):void {
trace("Res: " + res.result);
}
public function processResults2(res:ResultEvent):void {
trace("Res: " + res.result);
}
public function faultHandler(event:FaultEvent):void {
trace("Error: " + event.fault.faultString + ", details: " +
event.fault.faultDetail + ", trace: " +
event.fault.getStackTrace());
}
