Example 1 with ConfigurationLoaderStage1

use of au.org.emii.portal.config.ConfigurationLoaderStage1 in project spatial-portal by AtlasOfLivingAustralia.

the class ApplicationInit method contextInitialized.

Example 2 with ConfigurationLoaderStage1

use of au.org.emii.portal.config.ConfigurationLoaderStage1 in project spatial-portal by AtlasOfLivingAustralia.
