Hi,
i have installed PDI in a host A which belong to the same VPN network than my host B.
I can connect with ssh to A and i tried to launch spoon but i faced the following issue :

root@A:~/KETTLE/pdi# ./spoon.sh
ERROR 17-04 18:46:22,403 - Pentaho Data Integration - Fatal error : java.lang.UnsatisfiedLinkError: no swt-pi-gtk-3347 or swt-pi-gtk in swt.library.path, java.library.path or the jar file

Exception in thread "main" java.lang.NullPointerException

I have googled and found that one can use

export DISPLAY=<ip-of-your-X11-session>:0.0

but i don't know how to use it in Spoon.


Any idea, any help will be appreciate :-)

Thanks a lot

Hi!

You're actually missing a server side installation of GTK as the exceptions states:

Fatal error : java.lang.UnsatisfiedLinkError: no swt-pi-gtk-3347 or swt-pi-gtk in swt.library.path, java.library.path or the jar file

If you're just trying to execute a job/transformation try pan.sh instead of spoon.sh.

If you're trying to develop a job/transformation on that remote machine you'll have to get GTK installed on that remote machine.

Running on a remote host works with the "export DISPLAY=<ip>:0" command. However, you have to make sure that you have permissions to access the X11 session on the remote host.
Usually running "xhost +" or similar solves the issue.

I too am getting the error:
Fatal error : java.lang.UnsatisfiedLinkError: no swt-pi-gtk-3347 or swt-pi-gtk in swt.library.path, java.library.path or the jar file
when running on a remote system. The remote system does not have an X Server, but I would like the graphical output (via set DISPLAY=<IP Address>:0.0 to assist in debugging.

Can I just install the GTK+ libraries or will I be needing something else once that is installed? Do I need to install the full XFree86 X server or will I even be able to without a graphics controller?

[MattCasters]

You can live without the graphical controller, but you do need the X11 and gtk+ libs.

[SamSubterra]

So I grab the latest X11 and GTK libs and install them. Is there any other configuration that I will need to do to get spoon to find them?

[MattCasters]

None I can think of. It would highly depend on the operating system, etc, etc. You are completely on your own here.
