Given this scenario, which two must be true? (Choose two.)
A. The J2EE web container must support migration of objects that implement Serializable.
B. The J2EE web container must use the native JVM Serialization mechanism for distributing HttpSession
objects.
C. As per the specification, the J2EE web container ensures that distributed HttpSession objects will be stored
in a database.
D. Storing references to Enterprise JavaBeans components in the HttpSession object might NOT be supported
