Tjek af password

Ja.

Lidt hurtig kode:

    public static boolean check(String un, String pw) throws Exception {
        Class.forName("com.mysql.jdbc.Driver");
        Connection con = DriverManager.getConnection("jdbc:mysql://mysqlserver/mysqldb", "mysqlun", "mysqlpw");
        Statement stmt = con.createStatement();
        ResultSet rs = stmt.executeQuery("SELECT pwfield FROM usertable WHERE unfield='" + un + "'");
        if(rs.next()) {
            String realpw = rs.getString(1);
            return pw.equals(realpw);
        } else {
            return false;
        }
    }

OK ?
