103.
<auth-constraint><role-name>SALES</role-name></auth-

<role-name>SALES</role-name>
105.

106.
</security-constraint>

<security-constraint>
108.
<!--a correct url-pattern and http-method goes here-->
109.

- B. getClass().getResource("/WEB-INF/myconfig.xml")
- C. context.getResource("/WEB-INF/myconfig.xml")

Question #3
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() {
Tag docTag = findAncestor(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
} - B. public void doStartTag() {
Tag docTag = findAncestor(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
} - C. public void doStartTag() {
JspTag docTag = findAncestorWithClass(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
} - D. public void doTag() {
JspTag docTag = findAncestorWithClass(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
}
Correct Answer: D 🗳️
Question #4
Given:
1.package com.example;
2.3.
public abstract class AbstractItem {

Which two are valid standard action invocations that expose a scripting variable to the JSP page? (Choose two.)
- A. <jsp:useBean id="com.example.ConcreteItem"
scope="session" /> - B. <jsp:useBean id="item" class="com.example.ConcreteItem"
scope="session" /> - C. <jsp:useBean id="item" type="com.example.ConcreteItem"
class="com.example.AbstractItem"
scope="session" /> - D. <jsp:useBean id="item" type="com.example.ConcreteItem"
scope="session" />
Correct Answer: B,D 🗳️

<%= request.getParameter( "body" ) %>
</forum:message> - B. <forum:message from="My Name"
subject="<%= request.getParameter( "subject" ) %>">
My message body.
</forum:message> - C. <forum:message subject="My Subject">
My message body.
</forum:message> - D. <forum:message from="My Name" subject="My Subject" />
