Goal

Demantra 7.3 Web App will not connect to database.

Upgrade v7.2.0.2 to v7.3, create a WAR file and deploy to web server (Apache Tomcat 6.0)
JDBC Data Source is showing null values in the connection string so the web server cannot connect to the database.

In colaborator.log file:

FATAL appserver.fatal: The system had failed to establish connection to the configured Demantra data-source (JNDI name: jdbc/DemantraDS). Please verify data-source settings.
