Hello, i am using encryption and transferring data from a java app to a .NET app in C#. On the java side i am using a BufferedOutputStream, and on the .NET side i am using a BufferedStream too, created using a SecureNetworkStream and buffer size of 512.
The code is something like:
wrs.writeXml(bufout); // write the xml to the .NET client, where wrs is a WebRowSet object
on the .NET side:
BufferedStream ns = context.GetNetworkStream;
while (ns.CanRead && !DONE)
{
if (ns.CanRead)
{
DataSet ds = new DataSet();
ds.ReadXml(stream);
stream.Flush(); context.Mediator.AddResultSet(ds);
DONE = true; }
}
------------------
the Exception i get on the .NET's side is:
--------------------------------------

Do you have any idea what can be the cause for this ? Many thanks in advance.
