21. <input type = radio name = hobbyEnum value = SKING> Sking <br>
22. <input type = radio name = hobbyEnum value = SCUBA> SCUBA <br>
23. <! - - and more options - - >>
After the user submits this form, a confirmation screen is displayed with these hobbies listed. Assume that an application-scoped hobbies, holds a map between the hobby enumerated type and the display name.
Which EL code snippet will display Nth element of the user's selected hobbles?

A ${hobbies [hobbyEnum[N]}
B ${hobbies [paramValues.hobbyEnum[N]]}
C ${hobbies [paramValues @ ‘hobbyEnum’ @N]
D ${hobbies.get(paramValues.hobbyEnum[N]) }
E ${hobbies [paramValues.hobbyEnum.get(N)] }

You are building a web application with a scheduling component. On the JSP, you need to show the current date, the date of the previous week, and the date of the next week.
To help you present this information, you have created the following EL functions in the d namespace:
✑ Name : curData; signature: java.util.utilDate CurrentDate()
✑ Name : curData; signature: java.util.utilDate addweek (java.util.Date, int)
✑ Name: dateString; signature: java.util.String getDataString (jave.util.Data)
Which EL code snippet will generate the string for the previous week?

A ${d:dateString(affWeek(curDate(), -1)) }
B ${d:dateString [addWeek[curDate[], - ]] }
C ${d:dateString [d:addWeek[d:curDate[], - 1]] }
D ${d:dateString (d:addWeek(d:curDate(), -1)) }

Given a header in an HI IP request:

X-Retries: 4 -
A Which two retrieve the value of the header from a given HttpServletRequest request? (Choose two)

A request-getHeader("X-Retries")
B request.getlntHeader("X-Retries")
C request.getRequestHeader("X-Retries")
D request.getHeaders{"X-Retries").get(0)
E request.getRequestHeaders("X-Retries").get(0)

Given an HttpServletRequestrequest and HttpResponseresponse, which sets a cookie "username" with the value "joe" in a servlet?

A request.addCookie("username", "joe")
B request.setCookie("username", "joe")
C response.addCookie("username", "joe")
D request.addHeader(new Cookie("username", "joe"))
E request.addCookie(new Cookie("username", "joe"))
F response.addCookie(new Cookie("username", "joe"))

Which annotation enables a servlet to efficiently process requests of typo multipart/form-data that involve large files being uploaded by the client?

A @AcceptMultipart
B @MultiPartConfig
C @MultiPartFormData
D @WebServlet (multipart = true)

APIs for dynamically registering servlets and filters can be called at:

A Context initialization time
B Any time
C There is no way to dynamically register servlets and filters
D Context destruction time
E Injected into a servlet context

ServletRegistration.Dynamic can be used to configure (Choose two)

A Filter mappings
B add init params
C set asyncSupported to true
D add Listeners

A web application wants to register a new servlet at runtime using one of the servletContext.addServlet methods.
In the implementation of which method is it legal to perform this operation?

A AsyncListner.oncomplete
B Servlet.init
C ServletContextListener.contextInitialize
D ServletrequestListener.contextInitialize

You want to create a filter for your web application and your filter will implement
.servlet.Filter.
Which two statements are true? (Choose two)

A Your filter class must implement an init method and a destroy method.
B Your filter class must also implement javax.sarvlat.FilterChain.
C When your filter chains to the next filter, it should pass the same arguments it received in its doFilter method.
D The method that your filter invokes on the object it received that implements javax servlet.Filterchain can invoke either another filter or a servlet.
E Your filter class must implement a doFilter method that takes, among other things, an HttpServletRequest object and an HttpServletresponse object.

In ServletContext.getNamedDispatcher(string arg0) arg0 is the

A url of a servlet relative to the ServletRequest
B url of a servlet relative to the Context
C name of a servlet
D absolute url to any servlet in any Context

When using Servlet asynchronous API if you want to dispatch the request back to a particular url -"/url" within the same Servlet Context which of the following API would you use?

A ASyncContext.dispatch();
B AsyncContext.dispatch("/url");
C AsyncContext.dispatch(servletContext, "/url");
D AsyncContext.start(runnable);
E RequestDispatcher.fotward("/url");
F RequestDispatcher.forward(servletContext, "/url");

Which describes a trigger that causes a call to an AsyncListener?

A Completion of processing
B Receipt of a new request from the same client
C Addition of a new filter to the processing stream for this request
D Completion of each timer interval

C <jsp:useBean id="com.example.Product" scope="page"> <%= product.getName() %> </jsp:useBean>
D <jsp:useBean id="product" type="com.example.Product" scope="page" /> <%= product.getName() %>

Name: <input type="text" name="i1"><br>
Price: <input type="text" name="i2"><br>
<input type="submit">
</form>
