The Squeaky Beans Inc. shopping application was initially developed for a non-distributed environment.

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 by J2EE web containers.
In your web application, you need to execute a block of code whenever the session object is first created. Which design will accomplish this goal?
A. Create an HttpSessionListener class and implement the sessionInitialized method with that block of code.
B. Create an HttpSessionActivationListener class and implement the sessionCreated method with that block of code.
C. Create a Filter class, call the getSession(false) method, and if the result was null, then execute that block of code.
D. Create an HttpSessionListener class and implement the sessionCreated method with that block of code.
E. Create a Filter class, call the getSession(true) method, and if the result was NOT null, then execute that block of code.
Which interface must a class implement so that instances of the class are notified after any object is added to a session?
A. javax.servlet.http.HttpSessionListener
B. javax.servlet.http.HttpSessionValueListener
C. javax.servlet.http.HttpSessionBindingListener
D. javax.servlet.http.HttpSessionAttributeListener
