The tl:taskList and tl:task tags output a set of tasks to the response and are used as follows:
11.
<tl:taskList>
12.
<tl:task name="Mow the lawn" />
13.
<tl:task name="Feed the dog" />
14.
<tl:task name="Do the laundry" />
15.
</tl:taskList>
The tl:task tag supplies information about a single task while the tl:taskList tag does the final output. The tag handler for tl:taskList is TaskListTag. The tag handler for tl:task is TaskTag. Both tag handlers extend BodyTagSupport.
Which allows the tl:taskList tag to get the task names from its nested tl:task children?

A. It is impossible for a tag handler that extends BodyTagSupport to communicate with its parent and child tags.

B. In the TaskListTag.doStartTag method, call super.getChildTags() and iterate through the results. Cast each result to a TaskTag and call getName().

C. Create an addTaskName method in TaskListTag. Have the TaskListTag.doStartTag method, return BodyTag.EVAL_BODY_BUFFERE In the TaskTag.doStartTag method, call super.getParent(), cast it to a TaskListTag, and call addTaskName().

D. Create an addTaskName method in TaskListTag. Have the TaskListTag.doStartTag method, return BodyTag.EVAL_BODY_BUFFERED. In the TaskTag.doStartTag method, call findAncestorWithClass() on the PageContext, passing TaskListTag as the class to find. Cast the result to TaskListTag and call addTaskName().

E. In the TaskListTag.doStartTag method, call getChildTags() on the PageContext and iterate through the results. Cast each result to a TaskTag and call getName().

One of the use cases in your web application uses many session-scoped attributes. At the end of the use case, you want to clear out this set of attributes from the session object. Assume that this static variable holds this set of attribute names:
201.
private static final Set<String> USE_CASE_ATTRS;
202.
static {
203.
USE_CASE_ATTRS.add("customerOID");
204.
USE_CASE_ATTRS.add("custMgrBean");
205.
USE_CASE_ATTRS.add("orderOID");
206.
USE_CASE_ATTRS.add("orderMgrBean");
207.
}
Which code snippet deletes these attributes from the session object?

A. for ( String attr : USE_CASE_ATTRS ) {
session.remove(attr);
}

B. session.removeAll(USE_CASE_ATTRS);

C. for ( String attr : USE_CASE_ATTRS ) {
session.deleteAttribute(attr);
}

D. session.deleteAllAttributes(USE_CASE_ATTRS);

E. for ( String attr : USE_CASE_ATTRS ) {

What is true about Java EE authentication mechanisms?

A. If you want your web application to support the widest possible array of browsers, and you want to perform authentication, the best choice of Java EE authentication mechanisms is DIGEST.

B. If your deployment descriptor correctly declares an authentication type of CLIENT_CERT, your users must have a certificate from an official source before they can use your application.

C. If your deployment descriptor correctly declares an authentication type of BASIC, the container automatically requests a user name and password whenever a user starts a new session.

D. To use Java EE FORM authentication, you must declare two HTML files in your deployment descriptor, and you must use a predefined action in the HTML file that handles your user's login.

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 doStartTag() {
Tag docTag = findAncestor(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 doTag() {
JspTag docTag = findAncestorWithClass(this, DocumentTag.class);
((DocumentTag)docTag).addCitation(this.docID);
}
