B. DataSource ds;
try {
ctx = new InitialContext(env);

C. DataSource ds;
try {
ctx = new InitialContext(env);
ds = (DataSource) ctx.getConnection("MyDataSource");
} catch (NamingException ne) { }
D. DataSource ds;

Question #2
A developer wants to make use of a pre-existing tag library in a JSP. One of the tags in the library takes in two numbers, adds them together and outputs the result. The following directive appears at the top of the JSP that will use the tag:
<%@ taglib uri="http://www.mycorp/addition" prefix="calculate" />
Given the following except from the tag library descriptor, what syntax would the developer use in order to use the tag called add that adds the two numbers together?
<tag>
<name>add</name>
<tagclass>com.examples.Calculator</tagclass>
<attribute>
<name>first</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
<attribute>
<name>second</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>

A. <addition:add first="5" second="10" />
B. <calculator:add first="5" second="10" />
C. <calculate:add first="5" second="10" />
D. <calculate:add>first="5",second="10"</calculate:add>

Question #3
Why is it important to use an ALT attribute within an image tag in an HTML document?

A. It allows for an alternate image to be displayed if the primary image is not displayable in the requesting device.
B. It allows for an alternate image to be displayed if the primary image cannot be found.
C. It allows for animated images to be displayed by making use of the primary image and the image specified in the ALT attribute.
D. It allows for descriptive text to be displayed if the requesting device does not display inline images.

Question #4
In the JMS API for the publish-subscribe domain, how does a durable subscriber differ from a non-durable subscriber?

A. The application server delivers each message in a transactional context so that if a durable subscriber then rolls back the transaction, the state of the message reverts to that prior to delivery.
B. If a topic has a durable subscriber, the JMS provider logs all messages in a persistent media so that an application can inspect the log and extract messages at a later time.
C. Messages in topics that have durable subscribers remain in the topic until they expire or the subscriber connection to the JMS provider is closed.
D. If a durable subscriber becomes disconnected without unsubscribing and later reconnects, the subscriber receives messages that arrived while the subscriber was not active.

Question #5
