i have a problem on using a DA in my Product.
I have a Postgresql DA in my root-folder. If my Product is installed in the root-folder and i use:

self.con_obj = DA.DA('id','','pgsql','',query)
return self.con_obj()

When i install my Product in a sub-folder of the root-folder and i call the function above the following error occurs.

The database connection pgsql cannot be found.

Who can help me, please

Thanks as
