Re: Failed Connection (again) - Mailing list pgsql-jdbc

It would look like the url is wrong

it should look something like

"jdbc:postgresql://ebox2.sentricity.com/tickets"

note the "jdbc:postgresql" part
the "ebox2.sentricity.com" is the machine
the "tickets" is the db

my icq # is 14675561 if this doesn't work

Cheers,

Dave
