Yes middlegen generates a FlightBean.java. Then xdoclet generates a
FlightCMP.java that has the following definition (notice how it extends
the FlightBean):
public abstract class FlightCMP
extends airline.ejb.FlightBean
implements javax.ejb.EntityBean
{
public void ejbLoad()
{
}
public void ejbStore()
{
}
...
So FlightCMP extends FlightBean with the methods you're missing. Check
out the generated ejb-jar.xml file, notice the ejb-class:
<ejb-class>airline.ejb.FlightCMP</ejb-class>
This works, believe it or not.
