public class Config extends DataTypeMap
If running in a servlets environment, you must use the "Init" servlet and use <load-on-startup> to ensure it initializes before any calls are made to this class.
Then the Config class can be used to read settings as follows:
If running outside of a servlet environment, the following call should be made from the startup thread of the application before any Config APIs are called:
Config config = Config.getGlobal();
String propertyValue = (String)config.getProperty("propertyName");

propertyName- The name of the property to retrieve

.propertiesfiles, but before anything else in the system.
The simplest way to achieve this is to have your programmatic changes to config invoked from a servlet which is configured in
web.xml with a
load-on-startup parameter of 2, like this:
<servlet> <servlet-name>MyConfigChanges</servlet-name> <servlet-class>com.company.servlet.MyConfigChanges</servlet-class> <load-on-startup>2</load-on-startup> </servlet>The setting of "2" is important, because your code needs to run after the SmartClient
If running outside of a servlet environment, you should invoke your config override code from the startup thread of the application, after the call to
Config.initGlobalConfig() described in the class overview docs, but before any Config APIs are called.
