Hi Lothar ,
Thanks for your explanation. But this example program was written based on
the ChannelSession.java and shell.java programs that are present in the
jsch package, and this the way they use the read call and that is what is
causing us the issue.
So which means the way in which the channelSession.java and shell.java
program is written in jsch must also be changed.
Thanks
Aarthi
