Problem encountered:
Please set the correct server address, database name, user name and password to access the MySQL database.
To do so, edit the JDBC_URL property of WEB-INF/web.xml

Java Error:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.
----
My jdburl in web.xml is
<param-value>jdbc:mysql://localhost/queuemetrics?autoReconnect=true&amp;zeroDateTimeBehavior=convertToNull&amp;jdbcCompliantTruncation=false&amp;user=queuemetrics&amp;password=javadude</param-value>

"Could not create..." makes me think of a connection error. Are you sure MySQL is doing a bind on the correct address/port?
