resin-cmp, apache1.3.20, ultradev4, and postgresql7.0 problems

hello,

   i'm having trouble getting ultradev to make a connection with a postgresql
database on my server.  does anyone have any experience with this?  i have a
test .jsp script which can pull data out of a test db, but ultradev doesn't
want to make a connection.

when selecting the database connection for postgresql (some info downloaded
from http://www.animaproductions.com/ultra.html) we get the following error:

"While executing inspectConnection in postgresql_jdbc_conn.htm, a JavaScript
error occurred."


i'm not really sure where to look, any help would be appreciated.
cheers,
