I am getting the following error when I try to compile the java classes created by hbm2java. It seems it did not implement onSave(). Is this something we have to implement or should it have done it?

[javac] C:\java\Middlegen-Hibernate-r4\build\gen-src\com\ticket\dataobject\Ticket.java:11: com.ticket.dataobject.Ticket sh
ould be declared abstract; it does not define onSave(net.sf.hibernate.Session) in com.ticket.dataobject.Ticket
[javac] public class Ticket implements net.sf.hibernate.Lifecycle,Serializable {
[javac] ^
[javac] 1 error

Thanks.

you can uncheck the radion button in middlegen or delete implements ...LifeCycle into your POJO's.
Or if you need this implement, add the method onLoad, OnUpdtae, Ondelete.... to them.

Assuming that you using the latest version of hbm2java, Create a JIRA job so that hbm2java will be enhanced to generate the extra method(s).
Thanks.

eh - if you have listed an interface in the implements line then you would need to make the class abstract and extend the class your self or use the "class-code" meta tag for inserting extra code.

hbm2java have no idea on what the body of your onSave() method should contain, right ?

Yes your right - was not thinking.
