SOAP Runner Problem

Hi All,

I am trying to call a transaction as Web Service from Adobe Flex Application.

I am using the following code

<mx:WebService id ="SomeId"

wsdl="http://<ServerName>/Lighthammer/WSDLGen/<TransactionPath>"

useProxy="false" >

<mx:operation name="Xacute" >

<mx:request>

<XacuteRequest>

<InputParams>

<LoginName>LoginName</LoginName>

<LoginPassword>Password</LoginPassword>

<Input-Parameter> input value </Input-Parameter-->

</InputParams>

</XacuteRequest>

</mx:request>

</mx:operation>

</mx:WebService>

when tried to run the wsdl from Interned Explorer , it returns the expected result, but when the application run as the Flex Application, it returns the following error.

[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://<Servername>/Lighthammer/SOAPRunner/<TranaactionPath>"]. URL: http://<Servername>/Lighthammer/SOAPRunner/<TranaactionPath>"]. "]
