FYI: http://xml.apache.org/cocoon/installing/index.html has:

*UNIX with X server
...
*/Sun JDK 1.4 does not require graphics display anymore, but Java has to 
be started with the argument |-Djava.awt.headless=true|, and X libraries 
still must be installed./

[Ted T. Garrett II]

Running tomcat's startup.sh with -Djava.awt.headless=true included in 
the JAVA_OPTS or CATALINA_OPTS variables works fine for me, but I don't 
have a machine currently installed that doesn't have the x-windows 
libraries loaded.

Running ldd on /usr/lib/java/bin/java indicates no dependencies on x 
libraries, so I'd be willing to bet you can run it this way just fine.

Re: Cocoon on Headless Linux with JDK1.4

[Bert Van Kets]

Now you got me confused.
Has anybody tested Cocoon with Batik on a headless system with JDK 1.4 and 
no X whatsoever?  No libraries, no Xvfb???

I guess to be sure I'll have to test it myself.  If it really works without 
the X libs or Xvfb, then we must adjust the install docs.  They suggest 
that Xvfb is still necessary.

This seems to be the magic key -- a JVM 1.4 option to enable headless AWT:

  -Djava.awt.headless=true

   Headless support is now enabled by new graphics
   environment methods that indicate whether a display, keyboard, and
   mouse can be supported in a graphics environment.


I wonder what they are talking about? Are you sure it doesn't work as is 
with JDK 1.4?

I don't think so; at least Debian doesn't list any X packages as a
dependencies, and says Xvfb can be used as "an aid to porting the X
server to a new platform".

Doesn't Xvfb need the X libraries too?

I'll take it up with my ISP, but I doubt I'll be able to persuade him to 
install Xvfb.
I guess changing to another ISP would be the best option.

Cocoon on Headless Linux with JDK1.4

[Bert Van Kets]

My ISP can provide me with a headless web server running Suse 7.3, Resin 
2.4 (I think) and JDK 1.4.  He does not want to install the X libraries due 
to security reasons :-(
Is there an alternative?  AFAIK pja does not run on JDK 1.4
