The Commons Configuration software library provides a generic configuration interface which enables a Java application to read configuration data from a variety of sources.

The Apache Commons Configuration software library provides a generic configuration interface which enables a Java application to read configuration data from a variety of sources. Commons Configuration provides typed access to single, and multi-valued configuration parameters as demonstrated by the following code:

Double double = config.getDouble("number");
Integer integer = config.getInteger("number");

Configuration parameters may be loaded from the following sources:

  • Properties files
  • XML documents
  • Windows INI files
  • Property list files (plist)
  • JNDI
  • JDBC Datasource
  • System properties
  • Applet parameters
  • Servlet parameters

Different configuration sources can be mixed using a ConfigurationFactory and a CompositeConfiguration. Additional sources of configuration parameters can be created by using custom configuration objects. This customization can be achieved by extending AbstractConfiguration or AbstractFileConfiguration.
