[JSch-users] Application not exiting

[Chandolu, Y. <YCh...@ar...>]

Hi All,

=20

I am using ChannelExec to run a command remotely. I have attached code
at the very end. I ran the program in command prompt and the problem is
after I run the program it does not exit. I have to press <ctrl>+c for
the program to exit. I have taken the code from examples on the site.
Please suggest what should I do for the program to exit gracefully.

jsch 0.1.25 version

java 1.4.2_03

platform is windows 2000 professional
