I am developing a java playframework project.I am using Book class which is a sub class.It is extended from Item abstract class.I want to use com.avaje.ebean library and extend the Book class to add data to the database.So it means I have to extend two classes. Is there alternative way of doing this? Can you give me any solution.

You can do it by Multi-level inheritance:
class a {}
class b extends a{}
class c extends b{}
or else you have to go for interface concept, there you can implement n no. of classes
