Oracle Java Enterprise Edition 5 Web Component Developer Certified Professional Sample Questions:

1. Every page of your web site must include a common set of navigation menus at the top of the page. This menu is static HTML and changes frequently, so you have decided to use JSP's static import mechanism. Which JSP code snippet accomplishes this goal?

A) <%@ include file='/common/menu.html' %>
B) <%@ include page='/common/menu.html' %>
C) <%@ page import='/common/menu.html' %>
D) <%@ page include='/common/menu.html' %>
E) <%@ import file='/common/menu.html' %>
F) <%@ import page='/common/menu.html' %>


2. You have built a web application with tight security. Several directories of your webapp are used for internal purposes and you have overridden the default servlet to send an HTTP 403 status code for any request that maps to one of these directories. During testing, the Quality Assurance director decided that they did NOT like seeing the bare response page generated by Firefox and Internet Explorer. The director recommended that the webapp should return a more user-friendly web page that has the same look-and-feel as the webapp plus links to the webapp's search engine. You have created this JSP page in the /WEB-INF/jsps/error403.jsp file. You do NOT want to alter the complex logic of the default servlet. How can you declare that the web container must send this JSP page whenever a 403 status is generated?

A) <error-page>
<error-code>403</error-code>
<url>/WEB-INF/jsps/error403.jsp</url>
</error-page>
B) <error-page>
<error-code>403</error-code>
<location>/WEB-INF/jsps/error403.jsp</location>
</error-page>
C) <error-page>
<status-code>403</status-code>
<url>/WEB-INF/jsps/error403.jsp</url>
</error-page>
D) <error-page>
<status-code>403</status-code>
<location>/WEB-INF/jsps/error403.jsp</location>
</error-page>


3. DRAG DROP
Click the Task button.
Place the events in the order they occur.


4. You have created a web application that you license to real estate brokers. The webapp is highly customizable including the email address of the broker, which is placed on the footer of each page. This is configured as a context parameter in the deployment descriptor:
10.
<context-param>
11.
<param-name>footerEmail</param-name>
12.
<param-value>[email protected]</param-value>
13.
</context-param>
Which EL code snippet will insert this context parameter into the footer?

A) <a href='mailto:${initParam.footerEmail}'>Contact me</a>
B) <a href='mailto:${footerEmail}'>Contact me</a>
C) <a href='mailto:${contextParam.footerEmail}'>Contact me</a>
D) <a href='mailto:${initParam@footerEmail}'>Contact me</a>
E) <a href='mailto:${contextParam@footerEmail}'>Contact me</a>


5. A custom JSP tag must be able to support an arbitrary number of attributes whose names are unknown when the tag class is designed. Which two are true? (Choose two.)

A) The <dynamic-attributes>true</dynamic-attributes> element must appear in the echo tag TLD.
B) The <body-content> element in the echo tag TLD must have the value JSP.
C) The class implementing the echo tag handler must implement the javax.servlet.jsp.tagext.DynamicAttributes interface.
D) The class implementing the echo tag handler must implement the javax.servlet.jsp.tagext.IterationTag interface.
E) The echo tag handler must define the setAttribute(String key, String value) method.
