I was able to successfully embed it in the SAGE web server. Now for lots of
code cleanup...

Bob,
You did it! My preliminary tests show it works. I have to do some
modifications to get it embedded in Sage, but I think it will work fine.
Thanks,

OK, Jonathan. I think I found the problem. Please try what I just checked
in -- do a build, and then use jmolData.jar instead of jmol.jar.
Formerly:
JmolData.jar -s foo.spt
execute the script foo.spt with absolutely no graphics and no rendering,
including no image creation
now:
JmolData.ja
If awt is not there, you are out of luck. But with the -n flag there is no
creation of Display. But there might be a reference to it. Let me see.
Based on this discussion:
http://java.sun.com/developer/technicalArticles/J2SE/Desktop/headless/ we
should be able to do it.

Bob,
Thanks for trying...Your changes definitely reduce the error messages, but the
application is still looking for screen dimensions somewhere in the tree after
entering JmolPanel. It is making a call to the awt package. I'm suspicious
this is all associated with the allocation of a Display
Could be I'm wrong.Try what I just checked in. Be sure to use the
-ions t.spt
option (silent/no console/no graphics)
You won't get THAT error. but will it create an image? I used this script:
load $tylenol
write image 300 300 t.png

Nico,
I had forgot about fonts. Since we want to be able to put text in our
graphics, that may pretty much require us to have a GUI. For your information,
it appears that xpra/winswitch is an extension of the facilities provided by
xvfb and in some cases makes use of xvfb.

Hi,
You can check also tools like xvfb which can create a virtual display.
Even without the GUI, image generation may require a display for some image
operations (like fonts, ...), this is a Java limitation.
I used xvfb in several projects where I needed to create images without
having a real dis
I dug a little and agree it would be a significant undertaking to make the
image generation work without the GUI. That said, we might want to put that on
a long term to-do list.
My solution is to run an Xsession using xpra & winswitch. As long as I launch
the server process in the xpra Xsessi
You can't run it without graphics if you are going to create JPG files.
. If you are doing something else, you can use JmolData.jar, which has
no graphics.

Is this because of the try{...} at line 513 of JmolPanel.java? Shouldn't this
be inside the preceding if..., which checks to see if the display and splash
are enabled?

I've been working on using 12.0.45 as a server-side static graphics engine for
the SageMath group. I've run into the following problem. The server does not
run in an X-session, so there is no graphics environment. This causes an error
when Jmol is run as Jmol.jar -ionx. The error seems to im
