Consider the following code snippet of servlet code:

public void doGet (HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

PrintWriter out = response.getWriter();
String dbValue = getValueFromDB ();
if (dbValue == null) response.sendError (HttpServletResponse.SC_NOT_FOUND, "DB Lookup Failed");
response.sendRedirect ("Form.jsp"); }
If the getValueFromDB () method returns null , which of the following statements are true?
  • A) The code will work without any errors or exceptions
  • B) An IllegalStateException will be thrown
  • C) An IOException will be thrown
  • D) A NullPointerException will be thrown
    • [Ans: B]

    • When the sendError() API is called, the response is considered committed and should not be written to subsequently. Once the response is considered committed, any subsequent redirect operations will throw an IllegalStateException.

      In this example, the sendError() is invoked when the dbValue is null, which will cause the response to be committed. Hence, the subsequent response.sendRedirect () method will then cause an IllegalStateException to be thrown.
