[opencms-dev] Tomcat aborts on installing OpenCms

[SHIBUYA Katsutoshi]

Hi. I'm trying to start OpenCms.  Also I'm new to JAVA environment.
I'm installing OpenCms 6.2.1 on Fedora Core 5.  I installed tomcat5 and 
tomcat5-webapps packages with yum.
Then started it as "service tomcat5 start" and found java process is 
running.
I checked some jsp-examples and servlets-examples come with 
tomcat5-webapps and they looked like well.
As instalation guide, I copied "opencms.war" in webapps directory and 
accessed it via tomcat.  It was OK and I got a directory opencms in 
webapps.
Accessing opencms/setup, my browser shows "Welcome to the OpenCms 
setup" screen but after clicking "yes" and "continue", the tomcat 
server never responds.
I checked process and the java process has been lost.
I added JAVA_OPTS="-Djava.awt.headless=true" in 
/etc/tomcat5/tomcat5.conf (the start-script for tomcat reads it and put 
it as an argument to java process) and restarted tomcat, but nothing 
changed.
I found a message in "/var/log/tomcat5/catalina.out" as "Gtk-WARNING 
**: cannot open display:" so it looks like the problem with GUI 
library, but I don't have any more idea to solve it.
Can anyone help me?
