SSL Problem

Hi, I have seen the same problem in the past of this list but I don't know how (and if) it has been solved.
I'm trying to connect my java stand alone application with postgres 7.4.2 via SSL.

I followed the istructions
...
http://archives.postgresql.org/pgsql-jdbc/2003-08/msg00110.php
...
and then I tryed an SSL connection with pgAdmin: all works correctly
After I tryed to connect via java and the following error appear on the screen:

PostgreSQL 7.4.3 JDBC3 with SSL (build 214)
ssl = true
compatible = 7.4
loglevel = 2
Using Protocol Version3
Asking server if it supports ssl
Server response was (S=Yes,N=No): S
server does support ssl
converting regular socket connection to ssl

I'have no changed my java code. I have only changed the jdbc url by adding ?ssl&loglevel=2 at the end of the url.

Thanks in advance.
