If you have configured your tomcat in <frevvo-home>/tomcat/conf/server.xml to run on a port other than the default 8082, then you must set the port in the Url to the database connector to that different port number.
This will not work: http://localhost:8082/database/myStore/allOrders. Change 8082 to your tomcat port.
Your browser is not on the same machine as the database connector
If your web browser is not running on the machine where your database connector is installed then you cannot use "localhost" in the Url. You must replace this with the name or ipaddr of the machine running the database connector.
This will not work: http://localhost:8082/database/myStore/allOrders. Change "localhost" to the actual hostname or ipaddr.
The query returns a blank page after you changed the configuration.xml file location
