To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Objects with session scope are accessible from pages processing requests that are in the same session as the one in which they were created.
This option is correct because objects with session scope in JSP can be accessed from other pages that are part of the same session. The session scope ensures that the objects can retain their values across multiple requests within the same session.
Option B) It is not legal to define an object with session scope from within a page that is not session-aware.
This option is incorrect. In JSP, it is possible to define an object with session scope from within a page that is not session-aware. However, the object will only be accessible within the session for which it was created.
Option C) All references to the object shall be released after the associated session ends.
This option is correct. When a session ends, all objects with session scope associated with that session are destroyed and their references are released. This ensures proper memory management and prevents memory leaks.
Option D) References to objects with session scope are stored in the session object associated with the page activation.
This option is incorrect. References to objects with session scope are not stored in the session object associated with the page activation. Instead, they are stored in a separate session object that is associated with the session.
Based on the explanations above, the correct answer is A, B, C, D.
