SUN Sun Certified Web Component Developer for J2EE 5 認定 310-083 試験問題:

1. You have built a web application with tight security. Several directories of your webapp are used for internal purposes and you have overridden the default servlet to send an HTTP
403 status code for any request that maps to one of these directories. During testing, the
Quality Assurance director decided that they did NOT like seeing the bare response page generated by Firefox and Internet Explorer. The director recommended that the webapp should return a more user-friendly web page that has the same look-and-feel as the webapp plus links to the webapp's search engine. You have created this JSP page in the
/WEB-INF/jsps/error403.jsp file. You do NOT want to alter the complex logic of the default servlet. How can you declare that the web container must send this JSP page whenever a
4 03 status is generated?

A) <error-page>
< status-code>403</status-code>
< url>/WEB-INF/jsps/error403.jsp</url>
< /error-page>
B) <error-page>
< error-code>403</error-code>
< location>/WEB-INF/jsps/error403.jsp</location>
< /error-page>
C) <error-page>
< status-code>403</status-code>
< location>/WEB-INF/jsps/error403.jsp</location>
< /error-page>
D) <error-page>
< error-code>403</error-code>
< url>/WEB-INF/jsps/error403.jsp</url>
< /error-page>

2. Which three are true about TLD files? (Choose three.)

A) The web container recognizes TLD files placed in any subdirectory of WEB-INF.
B) When deployed inside a JAR file, TLD files must be in the META-INF directory, or a subdirectory of it.
C) A tag handler's attribute must be included in the TLD file only if the attribute can accept request-time expressions.
D) The web container can generate an implicit TLD file for a tag library comprised of both simple tag handlers and tag files.
E) The web container can automatically extend the tag library map described in a web.xml file by including entries extracted from the web application's TLD files.

3. DRAG DROP
Click the Task button.
Place the corresponding resources and directories in the proper web application deployment structure.

4. The Squeaky Beans Inc. shopping application was initially developed for a non-distributed environment. The company recently purchased the Acme Application Server, which supports distributed HttpSession objects. When deploying the application to the server, the deployer marks it as distributable in the web application deployment descriptor to take advantage of this feature.
Given this scenario, which two must be true? (Choose two.)

A) The J2EE web container must support migration of objects that implement Serializable.
B) As per the specification, the J2EE web container ensures that distributed HttpSession objects will be stored in a database.
C) The J2EE web container must use the native JVM Serialization mechanism for distributing HttpSession objects.
D) Storing references to Enterprise JavaBeans components in the HttpSession object might
NOT be supported by J2EE web containers.

5. Squeaky Beans Inc. hired an outside consultant to develop their web application. To finish the job quickly, the consultant created several dozen JSP pages that directly communicate with the database. The Squeaky business team has since purchased a set of business objects to model their system, and the Squeaky developer charged with maintaining the web application must now refactor all the JSPs to work with the new system. Which pattern can the developer use to solve this problem?

A) Intercepting Filter
B) Transfer Object
C) Business Delegate
D) Service Locator
