question about storing objects

Hi everybody,

I have written a storeAll()-method in a dao to store all given objects 
in one transaction (you find the code at the end of this mail).

Now please have a look at the following lines of code:
Account_2DAO dao1 = new Account_2DAO("DB1");
Collection<Account_2> accounts = dao1.findAll(Account_2.class);
logger.debug(accounts);
Account_2DAO dao2 = new Account_2DAO("DB2");
dao2.storeAll(accounts);

As you see, that there are two daos initialized. The first (dao1) 
retrieves all objects (using findAll()) from a database (DB1). The 
second (dao2) stores all retrieved objects into another database (DB2).
The findAll()-method works fine.

But the storeAll()-method only works when the line of code
logger.debug(accounts);
is called. If not, no data is inserted.

Any ideas what's going wrong (you find the class-descriptor file below)?

Abid


Code of storeAll():
public void storeAll(Collection<T> valueObjects)
		throws PersistentStoringException {

	if (valueObjects != null) {
		try {
			broker.beginTransaction();
			for (T valueObject : valueObjects) {
				broker.store(valueObject, ObjectModification.INSERT);
			}
			broker.commitTransaction();
		} catch (Exception e) {
			broker.abortTransaction();
			throw new PersistentStoringException(
					"Error while storing objects.\n" + e);
		} finally {
			if (broker != null && !broker.isClosed())
				broker.close();
		}
	}
}

Class-descriptor of Account_2:
<class-descriptor class="modulverwaltung.beans.Account_2"
	table="ACCOUNT_2" proxy="dynamic">
	<field-descriptor name="id" column="ID" primarykey="true"
		autoincrement="true" sequence-name="Account_Id_Seq" />
	<field-descriptor name="username" column="Username"
		jdbc-type="VARCHAR" />
	<field-descriptor name="role" column="Rolle" jdbc-type="VARCHAR" />
</class-descriptor>
