Correct Option: A,C

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) The statement is correct. The getRequestDispatcher method of the ServletContext class takes the full path of the servlet, whereas the getRequestDispatcher method of the HttpServletRequest class takes the path of the servlet relative to the ServletContext. This allows for flexibility in specifying the servlet path.

Option B) The statement is incorrect. The include method defined in the RequestDispatcher class can be used to access one servlet from another, regardless of whether any output has been sent to the server. It does not depend on the presence or absence of output.

Option C) The statement is correct. The getRequestDispatcher(String URL) method is indeed defined in both the ServletContext and HttpServletRequest classes. This allows for obtaining a request dispatcher from either the application context or a specific request.

Option D) The statement is incorrect. The getNamedDispatcher(String) method is not defined in the HttpServletRequest class. It is only defined in the ServletContext class. This method allows for obtaining a request dispatcher by specifying the name of the servlet.

Therefore, the correct statements are A and C.
