Hi All,
My C# web application calls a webservice to process a report. It sends XMLs as parameter and in response gets an XML node which stores Binay datatype bin.base64.
It makes an instance of the proxy class of webservice and makes a synchronous call to webservice GetReport() op.
Here is the code snippet -
************************************************** *************************************
wbFELIP.wsZProcessReport.ProcessReport report = new wbFELIP.wsZProcessReport.ProcessReport();
System.Xml.XmlNode rptData = null;
rptData = report.GetReport(strXmlReportRequest) ;
************************************************** ***********************************
WSDL -
[System.Web.Services.Protocols.SoapDocumentMethodAt tribute("http://tempuri.org/GetReport", RequestNamespace="http://tempuri.org/", ResponseNamespace="http://tempuri.org/", Use=System.Web.Services.Description.SoapBindingUse .Literal, ParameterStyle=System.Web.Services.Protocols.SoapP arameterStyle.Wrapped)]
public System.Xml.XmlNode GetReport(string vXML) {
object[] results = this.Invoke("GetReport", new object[] {
vXML});
return ((System.Xml.XmlNode)(results[0]));
}
/// <remarks/>
public System.IAsyncResult BeginGetReport(string vXML, System.AsyncCallback callback, object asyncState) {
return this.BeginInvoke("GetReport", new object[] {
vXML}, callback, asyncState);
}
/// <remarks/>
public System.Xml.XmlNode EndGetReport(System.IAsyncResult asyncResult) {
object[] results = this.EndInvoke(asyncResult);
return ((System.Xml.XmlNode)(results[0]));
}
************************************************** ***********************************
The above code was working fine since last 3 years but now it is returns error,
"Non-negative number required.\r\nParameter name: byteCount" .

To make sure I refreshed the WSDL , but still getting same error. I am able to create reports using the webservice in ASP using Get method. Moreover I spoke to webservice administrators , they can see the SOAP request coming on webserver and response is also getting genereated successfully. But I don't know what's wrong in my application code. I googled a lot to find but didn't get any clue.
Any kind of help on this issue will greatly be appreciated !

Santosh
