I have been studying Java EE and I posted a question on Stackoverflow to verify my understanding of “SessionBean”, here is the summary:

Stateless bean in client:

 

Stateful bean in client:

 

  • A stateless session bean, should not store a state in the bean instance, in order words, it’s class members should not be assigned by external values.
  • A stateful session bean, maintains it’s state until it’s “flushed”, a bean method that is annotated by “@Remove”
