Method Detail

loadPropertySet

protected void loadPropertySet(java.lang.String propertySetName,
                               java.util.Hashtable props,
                               java.util.Hashtable parameters)
                        throws java.lang.Exception

Load properties from a file, either on the filesystem or on the classpath. The filename is provided in the propertySetName, which when null, will force the default filename to be loaded. All system properties are added to the returned properties, replacing any properties of the same name already loaded.

If the file is not located relative to the current working directory if it is a relative filename, or at the absolute path if it is an absolute filename, then the file is looked for as a system resource on the classpath. If it still not found then an exception is thrown.

Overrides:

loadPropertySet in class ConfigurationLoader

Parameters:

propertySetName - filename or null to use default filename.

props - the container for the loaded properties.

parameters - customization properties.

Throws:

java.lang.Exception - if the file is not found on classpath or filesystem.
