Can not execute a simple update query with ms access

Question

Hi
I am trying to execute a simple update query , this is the code I am running : I get no exeptions but the db is not being updated .
When I copy my query into access it works !
The table / columns are spelled correctly and I am able to execute select queries.
can anyone figure out what is going on
Thanks shahar
public static void main(String[] args) {
MainManager mainManager = MainManager.getInstance();
Log log = Log.getInstance();
try {
log.writeDebugMessage("befor executing query");
//stmt.executeUpdate("update trainee set Trainee_Name = 'shahar&Rafi' where Trainee_Id = 1 ");
//stmt = null ;
PreparedStatement stmt1 = con.prepareStatement("UPDATE Trainee SET Trainee_Name =? WHERE Trainee_Id =?");
String name = new String("Shahar&Rafi");
int Id = 1 ;
stmt1.setString(1,name);
stmt1.setInt(2,Id);
System.out.println(stmt1.toString());
stmt1.execute();
log.writeDebugMessage("After executing query");
catch (SQLException e ){
System.err.println("SQLException: " + e.getMessage());
}

Hi All,
got the problem solved at last.
first, in the SQL string all the values must be within " ' "
for example:
INSERT INTO Trainee(Trainee_Id , Trainee_password , Trainee_Address, Trainee_Name , Trainee_Phone , Trainee_Gender , Trainee_SessionTime , Trainee_Purpose , Trainee_HealthStatus , Trainee_StartDate , Trainee_Birthday) VALUES (6,'333','hhhh','rafi',048231821,true,63,4,true, ('Feb 22, 2002'), ('Feb 22, 2002'))
second and more important,
a 'dummy' sql select query must be performed after an update query
example for code:
try{
DB.MainManager.getInstance().ExecuteUpdateQuery(A);
DB.MainManager.getInstance().getStatement().executeQuery("SELECT * FROM Trainee");
where A is the update query.
