If you are seeing any of the following exceptions while starting the ColdFusion server on RHEL 6/6.1/6.2
Unable to initialise License service: coldfusion.server.ServiceException
Unable to initialise Cryptograpic service: java.lang.NullPointerException
Unable to initialise Security service: java.lang.ExceptionInInitializerError.
Then you should
first verify if hostname and localhost are properly set-up are not by opening the
file /etc/hosts. Correct these if not set properly.
Once you fix that and restart the server it would start fine.
