After changing the port number from 8080 to 8181 of the http listener and checking on the box to enable its security from the admin console, glassfish wouldn't start anymore and I can't access the admin consol anymore (to cancel the changes I did) because for that glassfish needs to be running. I cannot afford to delete glassfish and reinstall it as I would lose all the configuration I already did for it.
Please provide a solution.
Thank you
