JS 2.2.2: access jetspeed javascript engine

Hi,

in my custom portal I use the global "jetspeed" javascript variable to 
get information from jetspeed. For example:

-> jetspeed.page.isUA() ==> to check if user is logged in
-> jetspeed.page.name ==> to get the current page name
-> jetspeed.page.getPortletArray() ==> to get the available portlets
...

Is there a possibility to do this in jetui?


best regards,

Frank
