Joomdle server URL

Hello,I would like to know if it's possible where joomlde stores the "joomla server url" so we can change it from command line. the field is in moodle at site administrator ->plugins->authentication-> joomlde.

This is stored in Moodle database, mdl_config table.
Name is "joomla_url"

I really hadn't noticed this before, and it is an odd place to be. It should be on mdl_config_plugins with the other ones, but I guess it has been like this since the start, and I never needed to look at it until now.
I will try to fix that in a future release if I can find a way to make upgrades work. I thnk it should be easy.
