1. Which statement is correct?  bag permits duplicate element values 2. The Spring MVC framework:  Implements validators as application otlects.  Supports several view technologies, such as JSP, Velocity, 111es, and JSF  Provides a clear separation between the controllers, models, and views. 3. The following figure shows the interaction between the presentation and business layers of a Web  Not All 4. Spring is a modular framework and has the following features:  Lightweight  Dependency Injection (DI)  Pluggability 5. The following table shows the comparison between Spring and EJB.  The spring framework is a popular . .  EJB does not provide . .  Spring enables you . . 6. What does “” means?  generate primary key 7. what does hibernate.hbm2ddl.auto create this means?  create tables automatically 8. Wath is JSF architecture?  Was developed using mvc . . .  Is driven by java . . . 9. Which statement is correct?  Only the Session that you obtained with sf.getCurrentSession() is flushed and closed automatically 10. Which component of the MVC design pattern represents data that an application persists?  Model 11. The cross-cutting concerns of an application can be modularized into special objects, called  Aspects 12. The following figure shows how the Spring beans are exposed to the JSF pages.  13. How can get a session object ?  SessionFactory.openSession(); 14. Which Spring class allows you to define pointcuts by using regular expressions?  15. Which of the following components of AOP is a point or a location in the application, where an advice can be plugged in?  Jointpoint 16. The features of Hibernate are:  It operates in only non-managed enwonments it can run outside an appIcation server container and within 17. Which of the following classes of the Hibernate API enables you to add a restriction in a criteria query?  18. Which of thc following elcmcnts is the parent element of the clcmcnt in the Spring configuration file?  19. What does sess.delete() do?  remove from database 20. Which of the following code snippets can be used to set the isolation level as read committed?  21. . Which of the following actions must be taken to make the directory structure valid and resources accessible?  Move the program JAR file  Move the Header tag file 22. How can you make a property be read from the database but not modthed in anyway?  By using the insert=”faIse” and update= “false” attributes. 23. The MVC design pattern is made up of the following components:  Model  Controller  View 24. What is HQL?  HQL stands for Hibernate Query Language 25. Which of the following features of Spring enables you to create separate modules for each cross-cutting concern?  AOP 26. What are POJOs?  POJO stands for plain old Java objects 27. The most important part of Web application development is  Implementation of the business layer 28. The core module:  Contains the most important component of the Spring framework, the bean factory container.  Provides the fundamental functionality of the Spring framework. 29. An object in the persistent state can be transformed into the detached state by invoking any of the class  org.hibernate.Session 30. The following figure shows the integration of Spring with Hibernate.  31. A Web application is spread across the following architectural layers:  Relational database layer  Presentation layer  Business layer 32. Using EJB and servlets to implement the business logic for a Web application may lead to the following :  The code for these applications is dependent on the J2EE container.  Unit testing ¡s difficult for such Web applications because the application code is closely associated with the J2EE 33. What do you map in the ORM process?  Tables with classes 34. There are core interface are used in just about every Hibernate application Using these interface, you can store and retrieve persistent objects and control transactions. Select the interface that you see  Configuration interface 35. The second parameter of the get () method accepts a ____________ reference, which is an identifier  Serializabe 36. Hibernate:  Enables the application to access data from any database.  Provides data persistence.  Is a powerful Object Relation Mapping (ORM) tool. 37. Problem Statement: You have to develop a Web application for ICHD Bank. Using This application, title customers of the bank should Costumer: To store information about the customers of the bank Account To store information about the existing accounts of the bank FundTransfer: To store information about the funds that are transferred from one account to the other The preceding entities need to work together to achieve the desired goal of the Web application. For this, you To develop a Web application for ICHD Bank, you need to perform, the following tasks.  Create a new project  Create the Customer  Create Account class 38. The database layer:  Communicates with the relational database.  Provides data persistence. 39. What does session.evict() method do?  remove the object and its collections from the first level cache 40. The Spring framework:  Takes care of all the Hibernate transactions.  Is placed between the application classes and the ORM tool  Enables you to use its features, such as DI and AOP to configure objects in your application.
