We've handled this by coding put and get methods that call the jsch
stuff in what amounts to a wrapper class and put methods' code in
try/catch blocks that concludes with this finally clause to ensure the
channel gets closed in the case of an abnormal exit:
} finally {
try {
if (channel != null && channel.isConnected()) {
channel.disconnect();
}
if (session != null && session.isConnected()) {
session.disconnect();
}
} catch (Exception e) {
logger.warn("Unable to close channel/session. " +
e.getMessage(), e);
}
;
}

Subject: [JSch-users] can sftpchannel close itself automatically?
Hi,
I use JSCH to implement a SFTP client, all work well except one
problem: If the method "ChannelSftp.disconnect()" is not called,
process will hang when stopping.
In normal exit case, that method could be called; But if process
exits in a abnormal way, and that method can not be called, I am afraid
that the hang problem will occur.
So I want to know whether there is some method in JSCH to set
"TIMEOUT" for a sftp session, once reaching the time, corresponding
session and sftpchannel will close automatically.
My use-case:
JSch jsch=new JSch();
Session session=jsch.getSession("XXX", "XXX", 22);
UserInfo ui=new MyUserInfo();
session.setUserInfo(ui);
session.connect();
Channel channel=session.openChannel("sftp");
channel.connect();
ChannelSftp channel=(ChannelSftp)channel;
//do some file transfer using channel
...
//when shutting down process
channel.disconnect();
session.disconnect();
Thanks.
Regards,
Atlantis
