I tried to write a simple appn using jpa

Business Interface:BookCatalogInterface.java


SessionBean : BookCatalogBean.java


persitent.xml

But getting error at the time of deployment on weblogic 10.3.3 server:

BookCatalogBean.java specify @Stateless(mappedName="entity/library/BookCatalogInterface")
and WebClient.jsp with bci = (BookCatalogInterface) ic.lookup("entity/library/BookCatalogInterface");
But getting error
Error:Unable to resolve 'entity.library.BookCatalogInterface'. Resolved 'entity.library'
I check jndi tree on console which specify Binding Name:
entity.library.BookCatalogInterface#entity.library.BookCatalogInterface
