//  JahiaPrivateSettings
//
//  18.11.2000  EV  added in jahia.
//  22.01.2001  FH  created readJahiaPropertiesFile() method and changed.
//  06.02.2001  AK  set readJahiaPropertiesFile as static method.
//  27.03.2001  AK  use the properties manager from org.jahia.utils.properties.
//  27.07.2001  SB  added jahiaLdapDiskPath
//  15.01.2002  NK  added mime types. mime types are loaded from web.xml files.
//
//  FIXME       create an authentification method in order to be sure that
//              this class is ONLY called by the Jahia servlet...
//              or crypt the data in the property file ?
