Hi,

I have a new problem about Object manager v.7.4.

When i run this code:

import java.io.*;

import com.db4o.*;

public class FirstStepsExample extends Util {
 final static String DB4OFILENAME = "db.yap";
 
 public static void main(String[] args) {
  ObjectContainer db = Db4oEmbedded.openFile(Db4oEmbedded
    .newConfiguration(), DB4OFILENAME);
  try {
   storeFirstPilot(db);
   //storeSecondPilot(db);
   //retrieveAllPilots(db);
   //retrievePilotByName(db);
   //retrievePilotByExactPoints(db);
   //updatePilot(db);
   //deleteFirstPilotByName(db);
   //deleteSecondPilotByName(db);
  } finally {
   db.close();
  }
 }

 public static void accessDb4o() {
  ObjectContainer db = Db4oEmbedded.openFile(Db4oEmbedded
    .newConfiguration(), DB4OFILENAME);
  try {
   // do something with db4o
  } finally {
   db.close();
  }
 }

 public static void storeFirstPilot(ObjectContainer db) {
  Pilot pilot1 = new Pilot("Michael Schumacher", 100);
  db.store(pilot1);
 
  System.out.println("Stored " + pilot1);
 }

}

I have my file db.yap.

When i try to open it with O.M, there is nothing !?
