Axion RDBMS problem

Question

Hi all,
I m working with the Axion RDBMS ,
I have a problem with the insertion of new records in the tables of my database, the selection is working properly but the insertion seems to be as it is in the transient mode not in the persistent one
Here is the code
class DatabaseConnection {
Statement stmt;
Connection con;
DatabaseConnection(){
try {
Class.forName("org.axiondb.jdbc.AxionDriver");
catch(ClassNotFoundException e) { e.printStackTrace(); }
try {
con = DriverManager.getConnection("jdbc:axiondb:MyDB:MyDB-DIR");
stmt = con.createStatement();
} catch (SQLException e) {     }
public void executeSql(String sql) {
stmt.execute(sql);
} catch (SQLException e) {           System.out.println(e.getMessage());       }
when I create a new instance of my DatabaseConnection class and I want to execute and insert it works but when I close and restart my application all the modification I did are not present
DatabaseConnection db = new DatabaseConnection();
db.executeSql(�INSERT INTO table (id, name) VALUES(1 ,�aName�)�);
if I make a select before I close my application I can see the record I inserted but after restarting the application it disappear
can any one help me ?

FWIW, I've decided to find out what exactly is an Axion RDBMS and found out that this freebie is still in an infancy stage (haven't really figured out whether it's a relational or just a plain database system) and the strange thing about this DB is that in order to make the changes permanent, you must:
1) commit the changes (even tho autocommit is set to true)
2) shutdown the DB and wait a bit before you close the connection
;o)
