Question: 1
To take advantage of the capabilities of modern browsers that use web standards, such as
XHTML and CSS, your web application is being converted from simple JSP pages to JSP
Document format. However, one of your JSPs, /scripts/screenFunctions.jsp, generates a
JavaScript file. This file is included in several web forms to create screen-specific validation
functions and are included in these pages with the following statement:
10. <head>
11. <script src='/scripts/screenFunctions.jsp'
12. language='javascript'
13. type='application/javascript'> </script>
14. </head>
15. <!-- body of the web form -->
Which JSP code snippet declares that this JSP Document is a JavaScript file?
A. <%@ page contentType='application/javascript' %>
B. <jsp:page contentType='application/javascript' />
C. <jsp:document contentType='application/javascript' />
D. <jsp:directive.page contentType='application/javascript' />
E. No declaration is needed because the web form XHTML page already declares the MIME
type of the /scripts/screenFunctions.jsp file in the <script> tag.
Answer: D
Question: 2
Given the JSP code:
10. <html>

14. to Squeaky Beans, Inc.

Question: 3
You have built a collection of custom tags for your web application. The TLD file is located in the
file: /WEB-INF/myTags.xml. You refer to these tags in your JSPs using the symbolic name:
myTags. Which deployment descriptor element must you use to make this link between the
symbolic name and the TLD file name?
A. <taglib>
<name>myTags</name>
<location>/WEB-INF/myTags.xml</location>
</taglib>
B. <tags>
<name>myTags</name>
<location>/WEB-INF/myTags.xml</location>
</tags>
C. <tags>
<tags-uri>myTags</taglib-uri>
<tags-location>/WEB-INF/myTags.xml</tags-location>
</tags>
D. <taglib>
<taglib-uri>myTags</taglib-uri>
<taglib-location>/WEB-INF/myTags.xml</taglib-location>
</taglib>
Answer: D
Question: 4

You have created a JSP that includes instance variables and a great deal of scriptlet code.
Unfortunately, after extensive load testing, you have discovered several race conditions in your
JSP scriptlet code. To fix these problems would require significant recoding, but you are already
behind schedule. Which JSP code snippet can you use to resolve these concurrency problems?
A. <%@ page isThreadSafe='false' %>
B. <%@ implements SingleThreadModel %>
C. <%! implements SingleThreadModel %>
D. <%@ page useSingleThreadModel='true' %>
E. <%@ page implements='SingleThreadModel' %>

QUESTION NO: 9
You are building a web application that will be used throughout the European Union; therefore, it
has significant internationalization requirements. You have been tasked to create a custom tag
that generates a message using the java.text.MessageFormat class. The tag will take the
resourceKey attribute and a variable number of argument attributes with the format, arg<N>. Here
is an example use of this tag and its output:
<t:message resourceKey='diskFileMsg' arg0='MyDisk' arg1='1247' />
generates:
The disk "MyDisk" contains 1247 file(s).
Which Simple tag class definition accomplishes this goal of handling a variable number of tag
attributes?
A. public class MessageTag extends SimpleTagSupport
implements VariableAttributes {
private Map attributes = new HashMap();
public void setVariableAttribute(String uri,
String name, Object value) {
this.attributes.put(name, value);
}
// more tag handler methods
}
B. The Simple tag model does NOT support a variable number of attributes.
C. public class MessageTag extends SimpleTagSupport
implements DynamicAttributes {
private Map attributes = new HashMap();
public void putAttribute(String name, Object value) {
this.attributes.put(name, value);
}
// more tag handler methods
}
D. public class MessageTag extends SimpleTagSupport
implements VariableAttributes {
private Map attributes = new HashMap();
public void putAttribute(String name, Object value) {
this.attributes.put(name, value);
}
// more tag handler methods
}
E. public class MessageTag extends SimpleTagSupport
implements DynamicAttributes {
private Map attributes = new HashMap();
public void setDynamicAttribute(String uri, String name,
Object value) {
this.attributes.put(name, value);
}
// more tag handler methods
}
Answer: E
QUESTION NO: 10
Given the JSP code:
<% request.setAttribute("foo", "bar"); %>
and the Classic tag handler code:
5. public int doStartTag() throws JspException {
6. // insert code here
7. // return int
8. }
Assume there are no other "foo" attributes in the web application.
Which invocation on the pageContext object, inserted at line 6, assigns "bar" to the variable x?
A. String x = (String) pageContext.getAttribute("foo");
B. String x = (String) pageContext.getRequestScope("foo");
C. It is NOT possible to access the pageContext object from within doStartTag.
D. String x = (String)
pageContext.getRequest().getAttribute("foo");
E. String x = (String) pageContext.getAttribute("foo",
PageContext.ANY_SCOPE);
Answer: D
