I have installed and configured Openfire server in my Ubuntu system and crated many users who use spark to login. Recently due to power failure my system got reboted. After the reboot openfire is not working. When I try to open this page “localhost:9090/login.jsp” it is opening the setup page where it ask me to reconfigure the server from thefirst step i.e chosing language. While continuing there are some errors comming. I have attached the error log. How to rectify the problem. In case if I need to re-install openfire means, how to backup the users profile from the server ?
