I am trying to persist some data in my JavaFX application. My code fails when attempting to create a table in my PersistenceManager class:
private final static String DATABASE_URL = "jdbc:sqlite:my.db";
private final static String DATABASE_DRIVER = "org.sqlite.JDBC";
// ...
Class.forName(DATABASE_DRIVER);
DriverManager.getConnection(DATABASE_URL);
connectionSource = new JdbcConnectionSource(DATABASE_URL);
// here it fails:
TableUtils.createTable(connectionSource,MyClass.class);
A file my.db
is actually created, but it is empty. When executing TableUtils.createTable, it triggers the following:

My Class is this:
@DatabaseTable(tableName = "myclass")
public class MyClass {
@DatabaseField(id = true)
private String nome;
@ForeignCollectionField(eager = false)
private Collection<MyOtherClass> risposte;
protected MyClass() {
super();
}
}
and MyOtherClass is:
@DatabaseTable(tableName = "myotherclass")
public class MyOtherClass {
@DatabaseField(id = true)
private String nome;
@DatabaseField(foreign = true)
private MyClass scheda;
protected MyOtherClass() {
super();
}
}
What should I look for correcting this?
