First of all, I'd like to thank you the time you're investing in trying to help me out.
Regarding the "listdir" command, I'd like to clarify that it only works on Windows environments. On Linux environments it's never worked.
(1) I can reach Pentaho server through both https and telnet protocols:
https://pentaho.uites.isciii.es (browser on Linux and Windows systems)
telnet pentaho.uites.isciii.es 443 (Linux command-line tool)
(2) I don't know how to know if my java trust the cert from my Pentaho server. Could you instruct to me how to find it out?
(3) Could you instruct to me how to do what you're suggesting? I think it has to be done within Pentaho-Spoon but... what step should I use? (I'm really sorry but I'm a newcomer to the Pentaho-Kettle world).
(4) I can confirm that I'm able to run ktr/kjb on Linux environment which had previously been exported from Windows environment. The command I've used is the following:
pan.sh -norep -file <myktrfile>
(5) As far as I know (it may be I'm wrong), Pentaho repositories are sandboxed, that is, you don't know where your repository is located. As a consequence, you just cannot invoke ktr/kjb located at the root of the repository.
Looking forward to reading a reply from you.
Thanks.
