Hi!
I am new on OJB.
I have only the following entry
try
{
broker = PersistenceBrokerFactory.defaultPersistenceBroker();
}
catch (Throwable t)
{
t.printStackTrace();
}
when i am trying to run the program am getting the following messages.
At the compile there is no errors. Why?
I am using j2sdk1.4.0_01
