Hi
 
I am trying to send a DIME attachment from .Net Client(C#) to Java(Axis Web Service).
I am getting the following error message:

"An unhandled exception of type 'System.Web.Services.Protocols.SoapException' occurred in system.web.services.dll
Additional information: java.lang.NullPointerException"
 
Could you tell me what could be the reason for this.

I have attached below all the necessary information:

===========================================================
.Net Code is as follows:

//Create a proxy class for the web service
GESAttachment.GESServiceServiceWse ws = new GESAttachment.GESServiceServiceWse();

//Convert the file to a Memory Stream
FileInfo fi = new FileInfo(FileName);
FileStream fs = fi.OpenRead();
byte [] bytes = new byte[fs.Length];
int numRead = fs.Read(bytes, 0, (int)fs.Length);
fs.Close();
MemoryStream ms = new MemoryStream(bytes);

//Create and Add the Attachment to the SOAPContext
DimeAttachment dimeAttach = new DimeAttachment("text/plain",TypeFormat.MediaType,ms);
ws.RequestSoapContext.Attachments.Add(dimeAttach);

//Call the Web service method
string strReturn = ws.processAttachments();

The TCPMONITOR exceptions is as follows:

      </soapenv:Body>
   </soapenv:Envelope>

JAVA WEB SERVICE CODE:
 
My java web service code is as follows:
 
// Getting the messageContext instance
MessageContext messageContext = MessageContext.getCurrentContext();
Message msg = messageContext.getRequestMessage();
Attachments attachments = msg.getAttachmentsImpl();
