Unexpected EOF in prolog Error

Question

I'm attempting to send a SOAP Message to another web service, however the response I get back throws an error: "Couldn't create SOAP message due to exception: XML reader error: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog".

The web service is written in Java, with a client written in VB.NET.

 Case SoapMessageStage.BeforeDeserialize
 readStr = New StreamReader(oldStream)
 writeStr = New StreamWriter(newStream)
 soapMsg1 = readStr.ReadToEnd()
 xDoc.LoadXml(soapMsg1)

Solution

Are you sure your massage is properly escaped and without any forbidden characters? I got that message a lot from parser if I forgot about it.
