Hello,

I'm having some problems connecting my jsp application using driver
postgresql-8.0-312.jdbc3 to a local postgresql database server. The
connection seems to be always refused whatever the user and/or database.

This is the code I wrote:

try

{

Class.forName("org.postgresql.Driver");

Connection db =
DriverManager.getConnection("jdbc

ostgresql://192.168.8.2/cgm","cgm","esper
anca");

for( SQLWarning warn = db.getWarnings(); warn != null; warn =
warn.getNextWarning() )

{

System.out.println( "SQL
Warning:" ) ;

System.out.println( "State
: " + warn.getSQLState() ) ;

System.out.println(
"Message: " + warn.getMessage() ) ;

System.out.println( "Error
: " + warn.getErrorCode() ) ;

}

...

This is the error returned:

Message: Connection refused. Check that the hostname and port are correct
and that the postmaster is accepting TCP/IP connections.

Error : 0

Hopping for an answer

This is a tcpip error message, caused by the server not listening on the
desired port. What have you set listen_addresses in postgresql.conf?
Probably only localhost. Try adding the server's external address or * to
listen on all available addresses.

Also make sure that you run postmaster with the -i parameter, so postgres
server can accept TCPIP connections

TIP 2: Don't 'kill -9' the postmaster
