imagej DISPLAY environment

[Lucy W Upchurch]

Hi,

We are trying to run imagej on a remote computer (mac Leopard OS) and
display the images on a local computer (another mac) via ssh.  I have set
my environment variable to the local machine when I ssh to the remote
machine.  I can do an XClock or Xeyes on the remote machine and it displays
on the local machine.  However, if I run imageJ, my images are displayed on
the remote computer, not my local machine.  I can not change the shell to
anything else as tcsh is required for other scripts/programs.  Any ideas on
how to get java to change the DISPLAY setting?  Thanks.

Lucy

What you are referring to with XClock and Xeyes is the X11 protocol.
ImageJ in Windows and OS X has nothing to do with X11. With
OS X 10.5.X you would have the option of using screen sharing
to do your task.

HTH,

There was a posting about this near issue on the ImageJ mailing list not
too long ago. The short version of the answer is that Apple's native
Java *is not* an X-windows application but rather a native Apple
application that uses Aqua; Aqua can't be tunneled in this way (and
maybe it can't be tunneled at all, idk). There are alternate Java
distributes that you may consider; I know of no other workarounds short
of sharing the entire desktop from one system to another.

FYI: You may find it revealing to google for a few key search terms such
as: tunneling apple java display

Good luck,

-Woody

I think Woody and Philip are both right
I haven't tried this but VNC might be the easiest solution.

Turn on "Desktop Sharing" (VNC) on 10.4 and up.
http://www.dssw.co.uk/blog/2007/05/14/a-vnc-server-is-included-in-mac-os-x-104/

Chicken of the VNC (VNC client).  Which I've used to VNC to linux boxes
and it works well.
