RE: Off-topic - Java and X11 Window Server
I am not an expert on any *nix system, but faced the same problem once. I had to set to DISPLAY varirable to :1.0 (export DISPLAY=:1.0). It is important that this is set for the same user that is running Tomcat. grts, Patrick -Original Message- From: Jose Euclides da Silva Junior - DATAPREVRJ [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 07, 2004 10:55 AM To: '[EMAIL PROTECTED]' Subject: Off-topic - Java and X11 Window Server Hi guys, Have anybody ever seen this error before?

RE: Off-topic - Java and X11 Window Server
Dear Jose, This is the document that put me on the right track. Set the DISPLAY variable as an environment variable for the user that start Tomcat. The variable has to be set before Tomcat is started snippet of document To run Xvfb in a manner that pleases Java, try: /usr/X11R6/bin/Xvfb :1 -screen 0 800x600x24 This will create a virtual display at :1.0 with a size of 800 by 600 pixels and a color depth of 24 bits. To ensure that Java draws to this display, you must set the DISPLAY environment variable to :1.0 before invoking Java. If Java throws any X11Environment exceptions, try changing the color depth or screen size. In my experience 16 or 24 bits has always worked. /snippet of document grts, Patrick -Original Message- From: Jose Euclides da Silva Junior - DATAPREVRJ [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 07, 2004 11:51 AM To: 'Tomcat Users List'; '[EMAIL PROTECTED]' Subject: RES: Off-topic - Java and X11 Window Server Dear Patrick, Where (and HOW ) should i set it?

RE: Off-topic - Java and X11 Window Server
If you are running java 1.4 you might be better off setting it up to run in a headless environment. I add this to my JAVA_OPTS when running startup.sh for tomcat to do this: JAVA_OPTS=-Djava.awt.headless=true Cheers, -gabe -Original Message- From: Patrick Willart [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 07, 2004 11:26 AM To: Jose Euclides da Silva Junior - DATAPREVRJ; 'Tomcat Users List' Subject: RE: Off-topic - Java and X11 Window Server Dear Jose, This is the document that put me on the right track.
