Question

Hi All,
I am using Soap Receiver Adapter.
*My Soap Request is:*
<?xml version="1.0" encoding="UTF-8" ?>
- <ns1:SendMessage xmlns:ns1="urn:MMWebSrvService">
  <strUsername>XIWSDL</strUsername>
  <strPassword>XIWSDL</strPassword>
  <strFrom>XI</strFrom>
  <strTo>123</strTo>
  <strMessage>abc</strMessage>
  <strSubject>333</strSubject>
  <strService>/SMPP/1</strService>
  <nOptions>0</nOptions>
  </ns1:SendMessage>
*My Soap Response from server is:*
  <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <!--  Inbound Message
  -->
- <tns:SendMessageResponse xmlns:tns="urn:MMWebSrvService" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:types="urn:MMWebSrvService/encodedTypes" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <return xsi:type="xsd:int">-1</return>
  <nIndex xsi:type="xsd:int">0</nIndex>
  <strErrorDescription xsi:type="xsd:string">String reference not set to an instance of a String. Parameter name: s</strErrorDescription>
</tns:SendMessageResponse>

you are getting a error response back from your soap partner..you have to have them to fix it..The above link is good if they are using dot net which is what i think it is..
