static java.util.Properties	locateProperties(java.lang.String[] appArgs, java.lang.Class mainClass) Procedure for populating a properties object at application startup. 1. if a cmd line arg is supplied, assume it is a file and attempt to load it as such. 2. if no cmd line arg, look in the classpath for resource whose name is derived from the main class name, qualified by package. 3. if resource in 2 does not exist, result is an empty properties map This procedure is useful only to applications, not really to classes embedded in e.g. web containers like Tomcat.

locateProperties

public static java.util.Properties locateProperties(java.lang.String[] appArgs,
                                                    java.lang.Class mainClass)

Procedure for populating a properties object at application startup. 1. if a cmd line arg is supplied, assume it is a file and attempt to load it as such. 2. if no cmd line arg, look in the classpath for resource whose name is derived from the main class name, qualified by package. 3. if resource in 2 does not exist, result is an empty properties map This procedure is useful only to applications, not really to classes embedded in e.g. web containers like Tomcat. There is no 'main' routine in the user application, and no assumptions can be made about the existence of a file system
