2 sql tables 1 java form...

Question

so im making a program for my 1st year exam and there is this create user form that is driving me crazy...
In the form there is these fields Firstname, Lastname, Address, Zipcode, City, Phonenr, EAN Nr, Ref, Username and Password.
In my MsSQL db i have 2 tables, login and user.
Table user has a pk that is named userid whch is a identity colum and table login has fk named userid.
Now what i want is that when the user adds info to the form and presses the okay buttom gets placed in the two different tables.
But i get this exception com.microsoft.sqlserver.jdbc.SQLServerException: The INSERT statement conflicted with the FOREIGN KEY constraint "FK_login_user". The conflict occurred in database "gruppe1", table "dbo.user", column 'userid'.
I hope some one can help, i have included a whole lot of code but if you need more say so..
Method for inserting user
public User createUser(User u) throws SQLException {
        Connection con = getConnection();
        try {
            PreparedStatement ps = con.prepareStatement("INSERT INTO bruger VALUES (?, ?, ?, ?, ?, ?, ?, ?)", PreparedStatement.RETURN_GENERATED_KEYS);
            ps.setString(1, u.getFirstName());
            ps.setString(2, u.getLastName());
            ps.setString(3, u.getAddress());
            ps.setInt(4, u.getZip());
            ps.setString(5, u.getCity());
            ps.setInt(6, u.getPhone());
            ps.setInt(7, u.getEan());
            ps.setString(8, u.getRefId());
            ps.executeUpdate();
            ResultSet keys = ps.getGeneratedKeys();
            keys.next();
            int usrid = keys.getInt(1);
            return new User(usrid, u.getFirstName(), u.getLastName(), u.getAddress(), u.getZip(), u.getCity(), u.getPhone(), u.getEan(), u.getRefId());
        } finally {
            con.close();
    }Method for inserting login info
    public Login createLogin(Login log) throws SQLException
      Connection con = getConnection();
      try
          PreparedStatement ps = con.prepareStatement("INSERT INTO login VALUES (?, ?, ?, ?)", PreparedStatement.RETURN_GENERATED_KEYS);
          ps.setString(1, log.getBrugernavn());
          ps.setString(2, log.getPassword());
          ps.setInt(3, log.getAccesslevel());
          ps.setInt(4, log.getBrugerid());
          ps.executeUpdate();
          ResultSet keys = ps.getGeneratedKeys();
          keys.next();
          int logid = keys.getInt(1);
          return new Login(logid, log.getBrugernavn(), log.getPassword(), log.getAccesslevel(), log.getBrugerid());
          finally
              con.close();
      }method for okay button
    private void jButton2MouseClicked(java.awt.event.MouseEvent evt)                                     
        User usr = new User();
        Login log = new Login();
        DBmanager dbman = new DBmanager();
            usr.setFirstName(firstNameField.getText());
            usr.setLastName(lastNameField.getText());
            usr.setAddress(addressField.getText());
            usr.setZip(Integer.parseInt(zipField.getText()));
            usr.setPhone(Integer.parseInt(phoneField.getText()));
            usr.setEan(Integer.parseInt(eanField.getText()));
            usr.setRefId(refField.getText());
            usr.setCity(cityField.getText());
            log.setBrugernavn(userNameField.getText());
            log.setPassword(passWordField.getText());
            log.setBrugerid(usr.getId());
            try {
                dbman.createUser(usr);
                dbman.createLogin(log);
            } catch (SQLException ex) {
                Logger.getLogger(createUserView.class.getName()).log(Level.SEVERE, null, ex);
    }                  It adds the user part into the user table but not the login part, i know it´s because it dosent transfer the userid from user table to login table..
How to do it?
I know my code is a bit messy so dont bash me :P
thank you

This is what i wanna do in java but i have trouble "translating" it
use gruppe1
insert into bruger (firstname, lastname, address, zipcode)
values ('ib', 'mathiesen', 'kongevej 2', 6510)
INSERT INTO login (username, userid)
values ('ib', @@IDENTITY)
SELECT userid
FROM user c
WHERE NOT EXISTS
SELECT *
FROM login x
WHERE x.userid = c.userid
Yes, I have a problem converting that too, since you have 2 seperate statements here instead of a complex insert--insert from a select.
You need something along the line of:
insert into login (username, userid)
  select username, userid from user c where not exists(
    select 1 from login x where x.userid = c.userid and
      c.username = <myUserName>)This is not tested SQL, but is of the form you need to use.
