I have installed tigase server in my linux machine.
After successfully installed tigase i found following in etc/init.properties.
--user-db = mysql
--admins = admin@username
--user-db-uri = jdbc:mysql://localhost/tigasedb?user=tigase&password=tigase12
config-type = --gen-config-def
--virt-hosts = username
--debug = server
Now, I want to install pubsub component with already installed server.
