Accessing the global Joomla! site configuration:

$jconfig =& JFactory::getConfig();

Retrieving a value from the configuration:

echo $config->getValue('config.sitename');

Although rarer than accessing the global Joomla! site configuration, sometimes it is necessary to access HUB-specific configurations. This can be done as follows:

$xhub =& XFactory::getHub();

Retrieving a value from the configuration:

echo $xhub->getCfg('hubShortName');
