Hallo!
Ich benutze eine objektorientierte Db.
Beim Zugriff darauf bekomme ich eine IllegalStateException! Soetwas hatte ich noch nie. Meine Recherchen haben mich aber nicht wiklich weitergebracht!

Java:
public void removeStock(Stock stock) {
db.delete(stock);
Java:
public void delete(Stock stock){
this.stock = stock;
ObjectContainer db = Db4o.openFile("StockTest.db");
ObjectSet result = db.queryByExample(stock);
Stock found = (Stock) result.next();
db.delete(found);
db.commit();
db.close();
}
