A servlet, which extends HttpServlet, needs to read various initialization parameters relating to a database, such as the database name, user ID and password. The servlet contains the following code to read the database.dbname parameter: String dbname = getInitParameter("database.dbname"); Where MUST the value of this parameter be entered? A. In a file called database.properties, located in the WEB-INF directory within the web module. B. In a file called database.dbname.properties, located in the WEB-INF directory within the web module.

If flag is false and no HttpSession object currently exists for this client, session is null. D. If flag is false and no HttpSession object currently exists for this client, an exception is thrown. E. If flag is false, a new HttpSession object cannot be created because the session manager's maximum limits have been reached. Answer: BC 21. A production web application contains many servlets, each representing one operation, which a user can perform in the application. The developer responsible for the application finds that it is hard to maintain and provides few opportunities for reuse of classes. Which of the following would be the BEST way to address these shortcomings? A. Replace the many servlets with a single servlet and use objects implementing the Command design pattern to manage request processing. B. Relocate the business logic to reside in the servlet classes, to reduce the number of classes in the application. C. Add a single servlet to receive requests from the user and then use a rules-based mechanism for deciding which of the many servlets to forward the request to. D. Move the controller logic from the servlets to the JSPs, to reduce the number of addressable resources in the application. Answer: A 22. A developer is writing a task() method, in a session bean, which makes use of several entity beans to perform a task. The session bean must record the invocation of the task using a LogEntry entity bean. The log entry must NOT be made if the task fails. Assume that the LogEntry bean is configured with 'Supports'. In order to GUARANTEE this behavior, the task() method of the session bean should be configured as: A. bean-managed transaction and explicitly begin an UserTransaction before creating the LogEntry instance and performing the task logic. Finally, have the task() method commit or rollback the transaction based on the success/failure of the task. B. 'Supports'. Within the task() method, create the LogEntry instance and perform the task logic. Finally, have the task method() call sessionContext.setRollBackOnly() if the task logic fails. C. 'RequiresNew'. Within the method, create the LogEntry instance and perform the task logic. Finally, have the task() method call sessionContext.setRollBackOnly() if the task fails. D. 'Mandatory'. Within the method, create the LogEntry instance and perform the task logic. Finally, have the task() method call sessionContext.setRollBackOnly() if the task fails. Answer: AC 23.

Slide 7: the transaction to rollback; a rollback was expected. What would correct this problem? A. Ensure that the business method throws an instance of javax.jts.TransactionRolledbackException. B. Ensure that the business method marks the current transaction for rollback by calling the setRollbackOnly() method on the EJBContext. C. Call rollback() on the current UserTransaction object. D. Call rollback() on the EJBContext. E. call setRollbackOnly() on the UserTransaction object. Answer: B 25. Customer and Address are BMP entity beans. The ejbCreate method for Customer is passed values for the properties of the Customer's address and it is necessary to ensure that an Address Entity is created as part of the same transaction that creates the Customer. Assuming the Address requires a reference to the Customer and there are no foreign key constraints enforced by the database, the BEST way to create the Address is to: A. Insert the Address data into the address table in the ejbCreate method of Customer. B. Insert the Address data into the address table in the ejbPostCreate method of Customer. C. Invoke the create() method of AddressHome from the ejbCreate method of Customer. D. Invoke the create() method of AddressHome from the ejbPostCreate method of Customer. Answer: D 26. A developer is writing a session bean which makes use of several entity beans to perform a task. The session bean must record the invocation of the task using a LogEntry entity bean. The log entry must be made regardless of the success of the task. What supports BEST this behavior? A. Provide two distinct operations on the session bean that would be invoked in sequence by the client code; one for creating the LogEntry and one for performing the task. B. Use 'RequiresNew' transaction attribute on the LogEntry bean to ensure that the creation of the LogEntry occurs on a separate transaction. C. Use 'Mandatory' transaction attribute on the LogEntry bean to ensure that the creation of the LogEntry occurs on a separate transaction. D. Have the task session bean invoke a createLogEntry() method on another session bean to ensure that the LogEntry is created outside the task transaction. Answer: B 27. Examination of the logs of a production web application have revealed that some servlets, which form part of an internal testing framework, are being invoked by external users, even though the test servlets are not mapped to URLs in the web.xml file. Which of the following would be the BEST way to fix this problem? A. Uncheck the "Serve servlets by classname" checkbox in the Extensions page of the Web Deployment Descriptor editor. B. Check the "Only serve mapped servlets" checkbox in the Servlets page of the Web Deployment Descriptor editor. C. Add mappings for the test servlets to the web.xml file. D. Remove the classnames for the test servlets from the MANIFEST.MF file for the web application. Answer: A 28. Part of the "page template", to be returned to the browser as a result of executing a JSP, is HTML which is updated daily, e.g., a "Press Releases" section. This is BEST done using which of the following tags? A. <%@ forward file="/pages/press_releases.html" %> B. <%@ include file="/pages/press_releases.html" %> C. <jsp:include page="/pages/press_releases.html" /> D. <jsp:forward page="/pages/press_releases.html" /> Answer: C 29. An IBMCampusOnline.com enterprise application retrieves and stores information about students and courses. Student and course entities are modeled as CMP entity beans. Students can see their courses and the tutor can see which students have enrolled in a course. To design the appropriate container-managed relationship:
Slide 8: A. the CMP beans have to provide a local interface B. the CMP beans are to be declared in the same package C. the beans have to expose remote interfaces for servlet access D. foreign keys must exist on the appropriate database tables Answer: AD 30.

The tag library URI must be specified in a taglib directive. C. Custom tags must be enabled in the web deployment descriptor. D. The mapping for the custom tag must be defined in the web deployment descriptor. E. The taglib module must be placed in the web application's lib directory.
