Answer 1

Are there any ways to obtain the value of a primary
key which is generated automatically by a server?Yes, if you are using JDBC 3.0 and a driver that supports it.
You do something like this (from the JDBC getting started guid at http://java.sun.com/j2se/1.4/docs/guide/jdbc/getstart/statement.html#1000569):
String sql = "INSERT INTO AUTHORS (LAST, FIRST, HOME) VALUES " +
                                                  "'PARKER', 'DOROTHY', 'USA', keyColumn";
int rows = stmt.executeUpdate(sql,
                                                                Statement.RETURN_GENERATED_KEYS);
ResultSet rs = stmt.getGeneratedKeys();
if (rs.next()) {
        ResultSetMetaData rsmd = rs.getMetaData();
        int colCount = rsmd.getColumnCount();
        do {
                for (int i = 1; i <= colCount; i++) {
                        String key = rs.getString(i);
                        System.out.println("key " + i + "is " + key);
        while (rs.next();)
else {
        System.out.println("There are no generated keys.");
}
