Help: cant get values from a resultset

Question

i have a class that contains all my MySQL statement and i am trying to use the results found from one of my select statements to pass on into another class which displays the results in a gui form. Here is my query:
public void profile(String user)
        try
             Class.forName(driver);
             Connection con = DriverManager.getConnection( url,db_user, db_pass);
             String username, name, email, dob, bio, gender, homepage, number;
             //find username and select all details
             String find = "SELECT Username, Full_name, Email, dob, Biography, Gender, Homepage, Contact_number FROM users WHERE Username = ? ";
             PreparedStatement ps1 = con.prepareStatement(find);
             ps1.setString(1, user);
            ResultSet rs = ps1.executeQuery();
            while(rs.next())
                //retreive information from the server
                username = rs.getString(1);
                name  = rs.getString(2);
                email  = rs.getString(3);
                dob = rs.getString(4);
                bio = rs.getString(5);
                gender = rs.getString(6);
                homepage = rs.getString(7);
                number = rs.getString(8);
                User_Profile profile = new User_Profile(username, name, email, dob, bio, gender, homepage, number);
                JOptionPane.showMessageDialog(null, username + bio + email, null, JOptionPane.ERROR_MESSAGE);
              con.close();
        catch( Exception e )
                 e.printStackTrace();
                 JOptionPane.showMessageDialog(null, "error," + e.getMessage(), null, JOptionPane.ERROR_MESSAGE);
    }As you can see, i am trying to pass on the variables username, name, etc to a new instance of my user_profile class but it doesnt for some reason. i dont get any comple errors so thats ok. i created messege dialog box from within the while statement above to see if a value is stored, and yes their is a value stored in my variables
below is the user profile class which shows my constructor that suppose to get the values from the query class in this code entered above       User_Profile profile = new User_Profile(username, name, email, dob, bio, gender, homepage, number);
    protected String username;
    protected String FullName;
    protected String Email;
    protected String DOB;
    protected String Biography;
    protected String Gender;
    protected String Homepage;
    protected String Con_Number;
    protected String crnt_user;
public User_Profile(String user, String name, String email, String dob,
                            String bio, String gender, String homepage, String number)
        initComponents();
        addWindowListener( this );
        //get values from sql query and store them here.
        this.username = user;
        this.FullName = name;
        this.Email = email;
        this.DOB = dob;
        this.Biography = bio;
        this.Gender = gender;
        this.Homepage = homepage;
        this.Con_Number = number;
     }the code below is used to display one of the values received from the query class, in this case returns null..
txt_name.setText(username)

Answer 1

Does the user String match the database String
exactly?
Some databases are case sensative.Sorry posted before done.
Also, ensure you do not have trailing spaces in one or both. I remember Oracle had this problem a few years ago using the Type 4 driver but not through ODBC.
