Abstract

The present invention provides a system and a method that employs a centralized properties server accessible from multiple applications using established computer network protocols. Applications that need configuration variables can make a request to the properties server. The server will then provide configuration values based on the attribute requested. Java applications may request property information by the use of the Java Remote Method Invocation and other applications may request information through a CORBA gateway server.
