A session-scoped attribute, product, is stored by a servlet. That servlet then forwards to a JSP
page. This attribute holds an instance of the com.example.Product class with a name property of
"The Matrix" and price property of 39.95.
Given the JSP page code snippet:
1. <jsp:useBean id='product' class='com.example.Product'>
2. <jsp:setProperty name='product' property='price' value='49.95'/>
3. </jsp:useBean>
4. <%= product.getName() %> costs <%= product.getPrice() %>
What is the response output of this JSP page code snippet?
A. Default costs 0.0
B. Default costs 49.95
C. Default costs 39.95
D. The Matrix costs 0.0
E. The Matrix costs 49.95
F. The Matrix costs 39.95

QUESTION NO: 225
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 requestscoped
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 page='${bodyURL}' />
B. <jsp:insert file='${bodyURL}' />
C. <jsp:include page='${bodyURL}' />
D. <jsp:include file='${bodyURL}' />
E. <jsp:insert page='<%= bodyURL %>' />
F. <jsp:include page='<%= bodyURL %>' />

PageContext.SESSION_SCOPE);

QUESTION NO: 227
You are creating a content management system (CMS) with a web application front-end. The JSP
that displays a given document in the CMS has the following general structure:
1. <%-- tag declaration --%>
2. <t:document>
...
11. <t:paragraph>... <t:citation docID='xyz' /> ...</t:paragraph>
...
99. </t:document>
The citation tag must store information in the document tag for the document tag to generate a
reference section at the end of the generated web page.
The document tag handler follows the Classic tag model and the citation tag handler follows the
Simple tag model. Furthermore, the citation tag could also be embedded in other custom tags that
could have either the Classic or Simple tag handler model.
Which tag handler method allows the citation tag to access the document tag?
A. public void doTag() {
JspTag docTag = findAncestorWithClass(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
}
B. public void doStartTag() {
JspTag docTag = findAncestorWithClass(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
}
C. public void doTag() {
Tag docTag = findAncestor(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
}
D. public void doStartTag() {
Tag docTag = findAncestor(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
}

QUESTION NO: 230
You web application uses a lot of Java enumerated types in the domain model of the application.
Built into each enum type is a method, getDisplay(), which returns a localized, user-oriented string.
There are many uses for presenting enums within the web application, so your manager has
asked you to create a custom tag that iterates over the set of enum values and processes the
body of the tag once for each value; setting the value into a page-scoped attribute called,
enumValue. Here is an example of how this tag is used:
10. <select name='season'>
11. <t:everyEnum type='com.example.Season'>
12. <option value='${enumValue}'>${enumValue.display}</option>
13. </t:everyEnum>
14. </select>
You have decided to use the Simple tag model to create this tag handler.
Which tag handler method will accomplish this goal?
A. public void doTag() throw JspException {
try {
for ( Enum value : getEnumValues() ) {
pageContext.setAttribute("enumValue", value);
getJspBody().invoke(getOut());
}
} (Exception e) { throw new JspException(e); }
}
B. public void doTag() throw JspException {
try {
for ( Enum value : getEnumValues() ) {
getJspContext().setAttribute("enumValue", value);
getJspBody().invoke(null);
}
} (Exception e) { throw new JspException(e); }
}
C. public void doTag() throw JspException {
try {
for ( Enum value : getEnumValues() ) {
getJspContext().setAttribute("enumValue", value);
getJspBody().invoke(getJspContext().getWriter());
}
} (Exception e) { throw new JspException(e); }
}
D. public void doTag() throw JspException {
try {
for ( Enum value : getEnumValues() ) {
pageContext.setAttribute("enumValue", value);
getJspBody().invoke(getJspContext().getWriter());
}
} (Exception e) { throw new JspException(e); }
}
