Usually there is an X-server running on the server I plan to use for the
automatic image generation with Jmol, so there will be no need to use
Xvfb. I just feared that the need for an X-server might cause problems
(especially if lots of windows would pop up, but this is resolved already).
I must do some more testing but I think the current capabilities will be
sufficient to replace rasmol by Jmol for our automatic image generation.
So there is no need to invest too much work into this.
The problem with the SGI computer that I reported (see below) will be
more distrubing, because it will presumably take quite a while until we
can switch from the SGI to our new linux server. I fear that it is
caused by the rather old java version (1.4.1_06) but the chance is
almost zero to get a newer version installed on that server.
With IRIX64 on an SGI computer (java 1.4.1_06) it doesn't work with the
same command (connected with 'ssh -X'). I get the following error message:
java.lang.IllegalArgumentException: Width (0) and height (16) cannot be <= 0
