Hi

Code

 

public static void main(String[] args) {
        
        try {
            System.out.println("Connecting..................");
            Class.forName("org.postgresql.Driver").newInstance();
            connection =
DriverManager.getConnection("jdbc:postgresql://10.10.10.101:6060/mydb",
"postgres", "welcome");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

 

Error

I am also sets

 

postgresql.conf

 

listen_addresses = '*'        # what IP address(es) to listen on;
                    # comma-separated list of addresses;

 

 

pg_hba.conf

 

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# IPv4 local connections:
host     all     all     10.10.10.100/32     trust
# IPv6 local connections:
host     all     all     0.0.0.0/0     trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
# host     replication     postgres     127.0.0.1/32     md5
# host     replication     postgres     ::1/128     md5
