SUN Sun Certified Web Component Developer for J2EE 5 Sample Questions:

Question 1

In a JSP-centric shopping cart application, you need to move a client's home address of the Customer object into the shipping address of the Order object. The address data is stored in a value object class called Address with properties for: street address, city, province, country, and postal code. Which two JSP code snippets can be used to accomplish this goal? (Choose two.)

A. <c:set var='order' property='shipAddress'>
< jsp:getProperty name='client' property='homeAddress' />
< /c:store>
B. <c:set var='order' property='shipAddress'
value='${client.homeAddress}' />
C. <c:set target='${order}' property='shipAddress'>
< jsp:getProperty name='client' property='homeAddress' />
< /c:set>
D. <c:set target='${order}' property='shipAddress'
value='${client.homeAddress}' />
E. <c:setProperty name='${order}' property='shipAddress'>
< jsp:getProperty name='client' property='homeAddress' />
< /c:setProperty>
F. <jsp:setProperty name='${order}' property='shipAddress'
value='${client.homeAddress}' />


Question 2

In which two locations can library dependencies be defined for a web application? (Choose two.)

A. the /META-INF/dependencies.xml file
B. the web application deployment descriptor
C. the /META-INF/MANIFEST.MF manifest file
D. the /META-INF/MANIFEST.MF manifest of a JAR in the web application classpath


Question 3

Which two about WAR files are true? (Choose two.)

A. WAR files must contain the web application deployment descriptor.
B. WAR files must be created by using archive tools designed specifically for that purpose.
C. The web container must allow access to resources in JARs in the web application library directory.
D. The web container must serve the content of any META-INF directory located in a WAR file.
E. WAR files must be located in the web application library directory.


Question 4

You have built a web application that you license to small businesses. The webapp uses a context parameter, called licenseExtension, which enables certain advanced features based on your client's license package. When a client pays for a specific service, you provide them with a license extension key that they insert into the <context-param> of the deployment descriptor. Not every client will have this context parameter so you need to create a context listener to set up a default value in the licenseExtension parameter. Which code snippet will accomplish this goal?

A. String ext = context.getInitParameter('licenseExtension');
if ( ext == null ) {
context.setInitParameter('licenseExtension', DEFAULT);
}
B. String ext = context.getAttribute('licenseExtension');
if ( ext == null ) {
context.setAttribute('licenseExtension', DEFAULT);
}
C. You cannot do this because context parameters CANNOT be altered programmatically.
D. String ext = context.getInitParameter('licenseExtension');
if ( ext == null ) {
context.resetInitParameter('licenseExtension', DEFAULT);
}
E. String ext = context.getParameter('licenseExtension');
if ( ext == null ) {
context.setParameter('licenseExtension', DEFAULT);
}


Question 5

Which statement is true if the doStartTag method returns EVAL_BODY_BUFFERED ?

A. The doAfterBody method is NOT called.
B. The setBodyContent method is called once.
C. The tag handler must implement BodyTag.
D. It is never legal to return EVAL_BODY_BUFFERED from doStartTag.
