JDBC connection to postgres via SSL

I have downloaded and compiled with SSL support Postgres 7.4.3.

I have enabled SSL connections in both the pg_hba.conf and postgresql.conf.

I have been able to connect via ssl to the database from a client using pgAdmin III without any problem.

However, from the same client my JDBC application cannot connect to the postgres server over SSL.

What do I have to do to enable this?

I have tried putting SSL=true as a query string parameter in my connection URL.  This causes an exception about not getting a proper SSL handshake, or something of the sort.

So my question is, what do I have to do to be able to connect to a postgres server via SSL from JDBC?

Thank you
