I reversed engineered a mysql table with annontations but it is not working with the session factory created when I created the the project. Can anyone recommend what changes I need to make to make the annontations sessionfactory work?

You said “Its not working with the session factory”. Are you getting some error or is the wizard not moving forward ? What exactly is happening.

Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

I tried to run this simple script and I got an error
EventsDAO events = new EventsDAO();
List test = events.findAll();
Iterator pairs = test.iterator();
while ( pairs.hasNext()){
Object[] pair = (Object[]) pairs.next();
Events event = (Events) pair[0];

This is the error I received
log4j:WARN No appenders could be found for logger (com.gerberdata.hibernate.EventsDAO).
log4j:WARN Please initialize the log4j system properly.
Exception in thread “main” java.lang.ClassCastException: com.gerberdata.hibernate.Events
at com.gerberdata.hibernate.testhibernate.main(testhibernate.java:19)

}

The “pears” iterator will return a list of Events; pairs.next() will return an Events object but you are casting it to Object[], hence the ClassCastException.

Hope this helps.
