Hi,
I try to develop a web service that by an ssh client get any
information from a host.
For the ssh client I use a .jar named Ganymed SSH2
the client work perfectly if I use it from a normal standalone java
main, but cause any problems if I use it from a web service.
In each one program i use the same IP User and Password but under web
service tomcat made this log
