This is java code, not a command shell instruction:

System.setProperty ('java.awt.headless"' 'true');

Probably it needs to be insterted into your program BEFORE any call to the java.awt stuff... but I am no java expert.
This is not a linux/readhad/centos problem per se. It means you miss some components to use the java.awt stuff expected by your program.
(f.e. X server, some libraries?)

The solutions offered do not resolve the problem or do not adress the problem.

 

by: MasasomiPosted on 2009-11-18 at 07:59:51ID: 25851090

Set JAVA_OPTIONS to include headless setting but still no joy starting X. The server causing the problem is a dedicated server hosted externally.  Created a new inhouse environment Installed Centos 5.3 from scratch.  Used Yum to install all required X relate packages.  Software installed without problem.  Thinks it may be something the management company disabled when setting up the server.

Normally it doesn't make a lot of sense to isntall X on a headless network oriented server.
Just because there is not graphical environment, AND X11 is not exactly known as a security oriented product.
It's just too large, parts of it need to be run as root or you need to give wide ranging permissions to hardware components to make it work...

Here is the explanation how it works:
http://java.sun.com/developer/technicalArticles/J2SE/Desktop/headless/

the procedure you mentioned (with " only in stead of mixed ' & ") is actualy the first call in main.

As a entry in the symbols that should presumably be, if you could specify it on the commandline...

export JAVA_OPTIONS="${JAVAOPTIONS} -Djava.awt.headless=true"
