running vibe 3.3

We lost our root password fro mysql and followed the TID for making a new one. after this we get a 404 error trying to connect to localhost and Catalina.out has this entry (among others):

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

The mysql root user password change was the only change - I suspect that java or tomcat or apache somwhere has a stale reference to the old root credentials, just dont know where to look or how to reset
