xaction and ssh2

Hi guys,

PDI v4.4
BI server CE v4.8
Design Studio v4.0

java -v = 1.6.0_27 (for all users, i.e. no alternatives)

Debian 7.1 with a 3.2 kernal

Problem:

Whenever I try to run an xaction with a PDI step that contains any of the various ssh2 options i get the following error:

Unexpected error loading class:
com/trilead/ssh2/Pentaho

this occurs against both ssh2 gets and puts, haven't tried sftp functions.

Job runs when launched from spoon. Would this be a permission error with the pentaho (biserver) user? If not any other clues?

Thanks,

Josh.
