Class AppConfigProperties

public class AppConfigProperties

extends java.lang.Object

AppConfigProperties is a concrete class which delivers container-specific configuration information about the Java Virtual Machine instance the application is running under. This is the default configuration class, which tries to pick up -D options on the java start command to locate the main application property file and the application configuration directory. The rest of the layered frameworks use this class to pick up configuration options in property files, either the main property file (application configuration directory + main application property file) or sub-property files (application configuration directory plus sub-property file name).

The defaults for application configuration directory is the current directory (.), that is, the directory where you invoked the java start command, and the main application property file is App.properties in that directory. You can override either of these by something like:

    java ... -Dorg.jlf.config.applicationConfigDir=/home/myApp -Dorg.jlf.config.applicationPropertyFile=MainApp.properties ...
 

Implementation note: This class is generally not exposed outside the package, it is wrapped by the AppInfo class. This class should have concrete subclasses which are container-specific (for example, WebLogicAppConfigProperties).

Method Detail

getApplicationConfigurationDirectory

public java.lang.String getApplicationConfigurationDirectory()

Retrieves the main application configuration directory. This directory should be the same directory as where the fully-qualified main application property file is located.

getApplicationPropertyFileName

public java.lang.String getApplicationPropertyFileName()

Retrieves the name of the main application property file

getApplicationName

public java.lang.String getApplicationName()

Retrieves the name for the application to uniquely identify it from other Java virtual machine instances running on the network. The default implementation at this level is host name concatenated with
