Hello,

How can I design the EJB as the following issues:

Suppose:

There is a super class "ItemBean"

The subclasses : BookItemBean, CDItemBean, etc.


In normal JavaBean, I can define as:

class BookItemBean extends ItemBean
class CDItemBean extends ItemBean

ItemBean itemBook = new BookItemBean();
ItemBean itemCD = new CDItemBean();

But how can I use EJB with CMP to design the above relations.


Best regards,
Eric
