Trouble setting up ssl cert authentication from java/hibernate

Hi!

I have a server which authenticates with ssl certificates. I have no
trouble using it with psql.

However I cannot figure out how to do the same with java. I have added
my private key and cert along with the CA cert to my keystore.
I set the javax.net.ssl.trustStore and javax.net.ssl.trustStorePassword
properties. But it seems that the underlying ssl does not use my
certificate/key.
Both the server and client reports "FATAL:  connection requires a valid
client certificate"
What am I doing wrong?

The juice of my hibernate config is:
<property
name="hibernate.connection.url">jdbc:postgresql://localhost:5433/archi?sslmode=required&ssl=true&</property>
<property name="hibernate.connection.username">mag</property>
<property
name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>

The juice of my test case:
         String password = new PasswordDialog(new Shell()).ask();
         System.out.println("keystore
path="+System.getProperty("javax.net.ssl.trustStore"));
         File keystorepath = new
File(System.getProperty("user.home"),".keystore");

System.setProperty("javax.net.ssl.trustStore",keystorepath.getAbsolutePath());
         System.setProperty("javax.net.ssl.trustStorePassword", password);
         System.out.println("keystore
path="+System.getProperty("javax.net.ssl.trustStore"));
         System.out.println("keystore
pwd="+System.getProperty("javax.net.ssl.trustStorePassword"));

         Session session = getSessionFactory().getCurrentSession();
         System.out.println("session="+session);
         session.beginTransaction(); // dies here
