I just got 1.0rc1 downloaded and junit-tested against the DB that ships with
the tgz. All was good.
So now I am trying to map my own classes, but run into the following
problem.
I am simply trying to pull all occurences of a class using the following
code (copied directly from the tutorial 1, with minor changes):
public TestMappings()
{
System.setProperty( Context.PROVIDER_URL, "t3://myserver:7001" );
System.setProperty( Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory" );
try
{
broker = PersistenceBrokerFactory.defaultPersistenceBroker();
}
catch (Throwable t)
{
t.printStackTrace();
}
}
public static void main( String[] args )
{
TestMappings me = new TestMappings();
me.execute();
}
private void execute()
{
Query query = new QueryByCriteria( AddressType.class, null );
try
{
java.util.Collection allCountries = broker.getCollectionByQuery(
query );
java.util.Iterator iter = allCountries.iterator();
while (iter.hasNext())
{
System.out.println(iter.next());
}
}
catch (Throwable t)
{
t.printStackTrace();
}
}
Which throws the following error:
[org.apache.ojb.broker.accesslayer.RsIterator] ERROR: OJB needs at least one

Here is the repository snippet mapping the AddressType entity:
