error starting tomcat - no display specified

Question

I am trying to install Ganib(project management tool), which make use of tomcat. After setup, I try to execute Start_ganib.sh, which ultimately try to start tomcat and fails with following error:

Using CATALINA_BASE:   /tmp/download/Ganib-1.3_with_jre/tomcat
Using CATALINA_HOME:   /tmp/download/Ganib-1.3_with_jre/tomcat
Using CATALINA_TMPDIR: /tmp/download/Ganib-1.3_with_jre/tomcat/temp
Using JRE_HOME:       ../../jre-lin/
Error: no display specified

Note: tomcat/bin/startup.sh and tomcat/bin/catalina.sh implicitly executed during this process.

Edit:

I tried doing:

export DISPLAY=localhost:0.0

but its showing another error message:

Error: cannot open display: localhost:0.0

To prevent the above error (assuming you do not require x-windows), you can startup tomcat in headless mode. Edit file catalina.sh and add the following to JAVA_OPTS

-Djava.awt.headless=true

Has it accepted that option ? You might want to add an echo to JAVA_OPTS to validate. – souser Dec 26 '13 at 18:01
