I'm trying to run this class, but I'm getting a noclassdeffound error, pointing to org/apache/commons/logging/LogFactory
And the stacktrace points to the SshClient-class.

Does the SshClient need the apache commons logging in the projects classpath or something?

Thanx

yeah, j2ssh library (including SshClient) uses commons logging and log4j api for logging.

(I should add that your pictures are beautiful!)
