I have a jboss/jetty installation that servers a few applications each with it's own MySQL database running in the same instance. How (or where) can I specify a unique username/password for each application to connect to MySQL. I don't care if they are plaintext, I just want each application to log in to mysql with it's own username which may/maynot have special permissions. Is there somewhere else I can specify the username/pw other than the jboss.jcml file????
