Answer 1

You should check your .conf, in my case openerp-server.conf, and check if there is something wrong on field db_password. This fields contains your openerp user's password to access your database. In my case my .conf looks like this:
[options]
; This is the password that allows database operations:
admin_passwd = myPass
db_host = false
db_port = false
db_user = openerp
db_password = 1234
addons_path = my_path/dev_core/addons, my_path/dev_core/my_modules
At the beginning I didn't set a password to my user openerp so my db_password was false and when I started working with jasper report I had to set a password to it, if it is your case you can set a password like this:
su root
su postgres
psql
postgres=# alter user openerp password '1234';
