Revision 3083

Added by Matt Jones about 18 years ago

Modified the configuration classes to allow configuration through the web interface of all of the properties set in the metacat.properties file. The layout of this form still needs work, in particular because java.util.Properties does not maintain any order for the properties, nor does it allow for metadata about each property to be set and saved in the file. We can probably overcome this by creating a shadow file that lists all of the options and their metadata (such as grouping, controlled values, etc).
