HOW WRITE GREEK CHARACTERS INTO MYSQL BY JSP ?

HALLOW TO ALL !

I'M USING MYSQL5.5 , TOMCAT7 & JSP. IN MY BROWSER I'M SEEING GREEK CHARS BECAUSE OF UTF-8 ENCODING . WHEN I RETRIEVE DATA FROM DATABASE BY SELECT * FROM... THAT'S IS FINE BUT WHEN I SEE INTO DB I CAN'T SEE THEM IN THE RIGHT WAY AS I HAD INSERTED THAT.

I HAVE TRIED MY DB IN UTF8 AND THE CHARSET -COLLATES UTFGENERALCI I TRIED GREEK DB BY THE GREEKGENERALCI & GREEK CHARSET TOO .

THE SAMPLE CODE IS BELOW

DROP database IF EXISTS XXXXX ; CREATE DATABASE XXXXX DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8generalci; USE XXXXX;

CREATE TABLE dokimi (
sid INT NOT NULL AUTO_INCREMENT , name VARCHAR(40) CHARACTER SET utf8 COLLATE utf8generalci ,

PRIMARY KEY(sid)
) DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8generalci;

String name = request.getParameter("n"); String sName = request.getParameter("e");

String connectionURL="jdbc:mysql://localhost:3306/XXXXX?user=userName&password=usersPassword&useUnicode=true&characterEncoding=utf8";

    Class.forName("com.mysql.jdbc.Driver").newInstance();    
    Connection connection = DriverManager.getConnection(connectionURL,"X","Y");
      PreparedStatement  ps = connection.prepareStatement("SET NAMES 'utf8'");
     connection.prepareStatement("SET character_set_client=utf8");


            String insertQuery="INSERT INTO dokimi (sid, name ) VALUES (?,?)";          ps.executeUpdate("SET CHARACTER SET 'utf8';");
            ps = connection.prepareStatement(insertQuery);

    try {

        ps.setInt( 1  ,0 ) ;
        ps.setString( 2 ,( name.trim()+" "+sName.trim() ) );   


                       int count = ps.executeUpdate(); 
           out.println(count + "row(s) affected");
           ps.close(); 
        }catch (SQLException s){}

COULD PLEASE HELP ME SOMEBODY WITH THAT ?
