[jcifs] NamedPipe question

[Jorg Schorr]

Hello,
 
I need to connect to an existing program (I do not have the source
code) on Windows written in C++ using NamedPipes to communicate. I have
this C++ code snippet which works, but when I try to do the same with
jCIFS it fails . Actually I tried to open the NamedFile as given in the
jCIFS JavaDoc when it has to be opened through CreateFile, but when I do
this it fails when I try to write on it, saying "File not found."
 
Any help is welcome.
Thanks.
