Hello again,

Still having problems with getting Servoy to run… ![:oops:]( "Embarassed")

Help would really be appreciated.  
My problem is that the default connection does not work, i.e port 5432 is (or does not) not open, giving the status as in picture below:

URL: jdbc:postgresql://localhost:5432/example

my test: telnet localhost 5432 =\> no connection

So, how to fix it?

PS i disabled my firewall but still no result

kind regards, JJ\_Delft

Perhaps you installed PostgreSQL with another instance running. In that case the port number is most likely 5433.

Hello Mr. Roclasi,

Thanks for responding

I tried to switch to 5433, but without succes.

I presume you’re Dutch, so i don’t have to transate the error msg below:

I get this for all ports.  
Any ideas?

Regards, JJ\_Delft

Is PostgreSQL running at all ?

NO!

I just found out.

I’m not completely sure if this should work, by double clicking in explorer, but i think so:

…\application\_server\postgres\_db\bin\psql.exe

also postgres.exe in same map does not start: get error msg, see below

Also i cannot install pgAdmin!! ?? i get the same error.

PgAdmin always installed fine on any computer (thusfar… ![:cry:]( "Crying or Very sad") )

Some help would be really appreciated…

JJ\_Delft,

If you go to the application\_server directory in a command window and type, the folowing command, what happens?

```auto
postgres_db\bin\pg_ctl start -D database -l postgres_db\postgres_log.txt

```
