EJB naming conventions

How does Oracle official JEE 7 tutorial say?

Items	Syntax	Example
EJB bean name	nameBean	HelloBean
EJB bean java class name	nameBean	HelloBean
Business interface	name	Hello

How is Java SE API doing?

Interface Name	Implementation Class Name
java.util.List<E>	AbstractList AbstractSequentialList ArrayList AttributeList LinkedList
java.util.Map<K,V>	AbstractMap Attributes AuthProvider ConcurrentHashMap ConcurrentSkipListMap EnumMap HashMap Hashtable IdentityHashMap LinkedHashMap Properties TreeMap

There is a lot examples in java api. Some abstract classes' name and their implementation classes are all named very well. Anyway, I never see something like IList, ListInter or ListInterface ......

How do you name your interface and enterprise session bean?
