Thread: Java database connectivity postgresql

Hello Sir,

I am trying to connect postgresql to java but I am not able .
Actually problem is that i have confugured the postgresql.conf and pg_hba.conf files as per given in the documentation
I had installed postgresql 8.2 version on Fedora Core 4
in my pg_hba.conf file my settings are as follows

# "local" is for Unix domain socket connections only
local   all         all                                 trust
# IPv4 local connections:
host    all         all         127.0.0.1/32            trust
# IPv6 local connections:
host    all         all         ::1/128                 trust

and in postgesql.conf file

listen_addresses = '*'
port = 5432
max_connections = 100

then i started the server with the following command
./postmaster -D /usr/local/pgsql/data -i
 server was started but i m not able to telnet
telnet localhost 5432

in the log files this error is coming
LOG:invalid length of startup packet

Plz help me asap. as i urgently need it in my project

Regards

This is to be expected. Connection via telnet to the DB is not supported ;-)
What the LOG entry tells you, though, is that the database is waiting for
network connections, so your setup should be OK.
Please try with psql: 'psql -h localhost -U <your username> template1'
You should either get an errormessage, or a login prompt.
