Section 10. Summary

Whew!

You are done with the first two examples. All the other examples are based on these

first two examples.

I have covered the definition of the CMP Entity bean; creating a Session bean that

references and uses the Entity bean; and creating a client that references and uses the

Session bean. Then I extended the Entity bean by adding a finder method to its home

interface. The implemenation of the finder method was defined with EJB QL in the

entity beans deployment descriptor.

If you made it this far, congratulations! You are at the top of the hill. It is all easy riding

down hill from here.

The next tutorial in this series will cover defining container managed relationships.
