Oracle Java Enterprise Edition 5 Web Component Developer Certified Professional Sample Questions:
1. In a JSP-centric shopping cart application, you need to move a client's home address of the Customer object into the shipping address of the Order object. The address data is stored in a value object class called Address with properties for: street address, city, province, country, and postal code. Which two JSP code snippets can be used to accomplish this goal? (Choose two.)
A) <c:set var='order' property='shipAddress' value='${client.homeAddress}' />
B) <c:set var='order' property='shipAddress'> <jsp:getProperty name='client' property='homeAddress' /> </c:store>
C) <c:set target='${order}' property='shipAddress'> <jsp:getProperty name='client' property='homeAddress' /> </c:set>
D) <c:set target='${order}' property='shipAddress' value='${client.homeAddress}' />
E) <jsp:setProperty name='${order}' property='shipAddress' value='${client.homeAddress}' />
F) <c:setProperty name='${order}' property='shipAddress'> <jsp:getProperty name='client' property='homeAddress' /> </c:setProperty>
2. You are building your own layout mechanism by including dynamic content for the page's header and footer sections. The footer is always static, but the header generates the <title> tag that requires the page name to be specified dynamically when the header is imported. Which JSP code snippet performs the import of the header content?
A) <jsp:include page='/WEB-INF/jsp/header.jsp'> <jsp:param name='pageName' value='Welcome Page' /> </jsp:include>
B) <jsp:include page='/WEB-INF/jsp/header.jsp'> <jsp:attribute name='pageName' value='Welcome Page' /> </jsp:include>
C) <jsp:import page='/WEB-INF/jsp/header.jsp'> <jsp:param name='pageName' value='Welcome Page' /> </jsp:import>
D) <jsp:import page='/WEB-INF/jsp/header.jsp'> <jsp:attribute name='pageName' value='Welcome Page' /> </jsp:import>
3. Given:
3.class MyServlet extends HttpServlet {
4.public void doPut(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
5.// servlet code here ...
26.
}
27.
}
If the DD contains a single security constraint associated with MyServlet and its only <httpmethod> tags and <auth-constraint> tags are:
<http-method>GET</http-method>
<http-method>PUT</http-method>
<auth-constraint>Admin</auth-constraint>
Which four requests would be allowed by the container? (Choose four.)
A) A user whose role is Member can perform a GET.
B) A user whose role is Admin can perform a PUT.
C) A user whose role is Admin can perform a GET.
D) A user whose role is Admin can perform a POST.
E) A user whose role is Member can perform a POST.
F) A user whose role is Member can perform a PUT.
4. Which two are characteristics of the Transfer Object design pattern? (Choose two.)
A) It reduces network traffic by collapsing multiple remote requests into one.
B) It increases the complexity of the remote interface by removing coarse-grained methods.
C) It increases network performance introducing multiple fine-grained remote requests which return very small amounts of data.
D) It increases the complexity of the design due to remote synchronization and version control issues.
5. Given the security constraint in a DD:
101.
<security-constraint>
102.
<web-resource-collection>
103.
<web-resource-name>Foo</web-resource-name>
104.
<url-pattern>/Bar/Baz/*</url-pattern>
105.
<http-method>POST</http-method>
106.
</web-resource-collection>
107.
<auth-constraint>
108.
<role-name>DEVELOPER</role-name>
109.
</auth-constraint>
110.
</security-constraint>
And given that "MANAGER" is a valid role-name, which four are true for this security constraint? (Choose four.)
A) MANAGER can do a TRACE on any resource in the /Bar/Baz directory.
B) DEVELOPER can do only a POST on resources in the /Bar/Baz directory.
C) MANAGER can do a GET on resources in the /Bar/Baz directory.
D) DEVELOPER can do a TRACE on any resource in the /Bar/Baz directory.
E) DEVELOPER can do a GET on resources in the /Bar/Baz directory.
F) MANAGER can do a POST on any resource in the /Bar/Baz directory.
