Thread failure in WLS 6.1 SP3
Robin Ladebue
Hello,
I'm attempting to use Sshtools (see www.sshtools.com) in a J2EE application to
open an SFTP
session and transfer a file from a remote server. While trying to connect, I
get a "thread
failed" error message and a corrupted MAC exception. I am using 1.3.1 of the
JDK
(I have no choice here) and running my application in Weblogic (version 6.1 sp3).
I can connect to the remote host via the ssh command line interface and when I
run my
programs run successfully when I execute them standalone. Any help is appreciated!
Log and stack trace: (the interesting stuff is near the end):
JAVA version is 1.3.1_03
