Ok.

As I read in another thread, client_encoding does not matter for the
JDBC driver. It will change it to UNICODE when you connect. It probably
does this because all java strings are unicode.
But it will probably matter for your psql connections, if any.

Try to change this to
<%@ page lanuage="java" pageEncoding="UTF-8" contentType="text/html;charset=UTF-8" %>

Have you tried putting unicode characters inside the db using pgsql? And
then showing them using the web-tier?
I have used tomcat as the webapp-server for many applications, and it
defaults to ISO-8859-1 character set for POST forms. Strange it is.
You can change this by calling
request.setCharacterEncoding("UTF-8");
before you get any data from your form.
Maybe the pageEncoding="UTF-8" changes this? I have not used that option
before.
Please check again that the data that you put in the database using JDBC
is not garbage due to characterset conversion.

I hope this helps,
