Why is the username and password incorrect?

Question

PostgreSQL

Hello!
I install kwoksys, I have postgresql and it is configured like this:

db.serverHost  = localhost
db.serverPort   = 5432
db.name          = kwokdb
db.username   = postgres
db.password    =postgres

I want to install jre and tomcat (+ connecting to the database)

/usr/kwok/./server/jre1.6.0/bin/java -jar /usr/kwok./database/schemasetup-2.6.8.jar install database=kwokdb username=postgres password=postgres

And it gives an error:
password authentication failed for user "postgres:. Cause: null
Tell me where I messed up? :_

psql -h localhost -p 5432 -U postgres -W
