Problem with DIME Headers

[Jonathan Boston <j....@anautics.com>]

Hello,

Our project is using an Axis web service with a .NET (C#) client. We're
using DIME attachments for transferring files. The client is able to
upload files fine (tested up to 50MB files), but downloads from the
server only work for files less than 4MB. My understanding is that files
over 4MB will be chunked, which is exactly what we want. The problem
comes when we try to read the chunk flag of the DIME header. Here is the
C# code that we are trying to use to check the chunk flag:

		webService.EndsendAttachToClient(ar);
		if (webService.ResponseSoapContext.Attachments.Count ==
1)
		{
			DimeReader dr = new
DimeReader(webService.ResponseSoapContext.Attachments[0].Stream);
			DimeRecord rec = dr.ReadRecord();//throws error
on attempted read

			MessageBox.Show("Chunked: " +
rec.Chunked.ToString());
		...

The call to DimeReader.ReadRecord() throws the following exception:

Microsoft.Web.Services2.Dime.DimeFormatException: WSE306: The DIME
record should have the following version: 1. Instead, the DIME record
contained the following version: 12. at
Microsoft.Web.Services2.Dime.DimeRecord.ReadHeader()

When checking Google for some help, I could only find errors that stated
the record contained version 7, instead of 12 like ours. Even still,
those problems didn't seem to match up with ours.

Does anyone have an explanation for this? Any help would be appreciated.

Our setup:
	Axis version 1.2.1, applied patch from
http://issues.apache.org/jira/browse/AXIS-2084?page=comments#action_1231
5937 for dime attachments.
	Using .NET Web Services Enhancements 2.0
