BTW - It should be possible to invoke Kepler without a display.
This has been done in the past and is covered elsewhere<br>
<br>
However, when I need to invoke Ptolemy with a display on a headless
machine, I use Xvfb, which is a virtual framebuffer. <br>
By starting up Xvfb and then setting the DISPLAY, I'm able to run
350+ demos and export the results to HTML.<br>
<br>
1. Install Xvfb on your
machine
<br>
yum install
Xvfb
<br>
2. Start up the
display
<br>
Xvfb :1 -screen 0 1024x768x24
&
<br>
export
DISPLAY=localhost:1.0
<br>
<br>
I've done this under Linux and Solaris.<br>

<div>Hi,</div>

</div>
<div>I think that it is possible that there are new modules to
download for your version, and for this reason the execution
(too in command line) tries to launch the X11. We changed the
configuration.xml in
kepler_2.2/module-manager-2.2.0/resources/configurations as
follow:</div>

<div>1. Then, there is a special Kepler for a

<div>2. Can we disable the ptolemy java gui without
JAVAFLAGS or the -Djava.awt.headless=true for
headless gui exec?</div>
<div>3. Maybe only redirecting the X11 DISPLAY to a
null or fake xhost we can solve it?</div>
