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

Question 1

You have built your own light-weight templating mechanism. Your servlets, which handle each request, dispatch the request to one of a small set of template JSP pages. Each template JSP controls the layout of the view by inserting the header, body, and footer elements into specific locations within the template page. The URLs for these three elements are stored in request-scoped variables called, headerURL, bodyURL, and footerURL, respectively. These attribute names are never used for other purposes. Which JSP code snippet should be used in the template JSP to insert the JSP content for the body of the page?

A. <jsp:insert file='${bodyURL}' />
B. <jsp:include page='<%= bodyURL %>' />
C. <jsp:insert page='${bodyURL}' />
D. <jsp:include file='${bodyURL}' />
E. <jsp:include page='${bodyURL}' />
F. <jsp:insert page='<%= bodyURL %>' />

Question 2

Which JSTL code snippet produces the output "big number" when X is greater than 42, but outputs "small number" in all other cases?

A. <c:choose test='<%= (X > 42) %>'>
<c:then>big number</c:when>
<c:else>small number</c:otherwise>
</c:choose>
B. <c:if test='<%= (X > 42) %>'>
<c:then>big number</c:then>
<c:else>small number</c:else>
</c:if>
C. <c:choose test='<%= (X > 42) %>'>
<c:when>big number</c:when>
<c:otherwise>small number</c:otherwise>
</c:choose>
D. <c:if>
<c:then test='<%= (X > 42) %>'>big number</c:then>
<c:else>small number</c:else> </c:if>
E. <c:choose>
<c:when test='<%= (X > 42) %>'>big number</c:when>
<c:otherwise>small number</c:otherwise>
</c:choose>

Question 3

You have built a web application that you license to small businesses. The webapp uses a context parameter, called licenseExtension, which enables certain advanced features based on your client's license package. When a client pays for a specific service, you provide them with a license extension key that they insert into the <context-param> of the deployment descriptor. Not every client will have this context parameter so you need to create a context listener to set up a default value in the licenseExtension parameter. Which code snippet will accomplish this goal?

A. String ext = context.getAttribute('licenseExtension');
if ( ext == null ) {
context.setAttribute('licenseExtension', DEFAULT);
}
B. You cannot do this because context parameters CANNOT be altered programmatically.
C. String ext = context.getInitParameter('licenseExtension');
if ( ext == null ) {
context.resetInitParameter('licenseExtension', DEFAULT);
}
D. String ext = context.getParameter('licenseExtension');
if ( ext == null ) {
context.setParameter('licenseExtension', DEFAULT);
}
E. String ext = context.getInitParameter('licenseExtension');
if ( ext == null ) { context.setInitParameter('licenseExtension', DEFAULT); }

Question 4

Which activity supports the data integrity requirements of an application?

A. using HTTPS as a protocol
B. using an LDAP security realm
C. using HTTP Basic authentication
D. using forms-based authentication

B. <jsp:useBean id="product" class="com.example.Product" />

C. <jsp:useBean id="product" class="com.example.Product">
<jsp:setProperty name="product" property="name"
value="${name}" />
<jsp:setProperty name="product" property="price"
value="${price}" />
</jsp:useBean>
D. <jsp:useBean id="product" class="com.example.Product" />
<% product.setName( request.getParameter( "name" ) ); %>
<% product.setPrice( request.getParameter( "price" ) ); %>
