Answer / venu bandla
dao design pattern is used to seperate data access logic from bussiness logic so the dao class contains only database connection related code,Dto design pattern is used to transfer the data from one component to another component and dto is a simple javabean.Vo design pattern is used to store the data in the form of objects and tranfer it

Answer / srikanth addani
DAO refers Data Access Object exclusively to write the code of data base server i.e establish connection with data base writing sql queries.DTO meant for DataTransferObject the main advantage is in order to resolve the problems of method parameters.VO meant for Value Object in order to display the output..

Interact with the action and set the request parameter on the action 3. Provide post-processing logic after invoking the action 4. Modify the result 1, 2, 3 2, 3, 4 1, 2, 4 1, 2, 3, 4 2.Interceptors can be used for which of the following tasks? 1. Checking security and bottleneck 2. Tracing the log 3. Validating user input 4.

Apache Struts is a Java based framework that separates the application logic from the presentation layer. Action is based on pull-MVC framework which means that the data to be displayed is pulled from the action class which is a POJO class acting as a model in the Web application. OGNL is a powerful expression language that allows you to refer and manipulate the data present on the ValueStack. Declarative architecture enables you to integrate the different components present in the Web application either using XML files or Annotations. 5.Which of the following are the examples of helpers? 1. Action Interface 2. ActionSupport Class 3. ActionImplement Interface 1, 2 2, 3 1, 3 1, 2, 3 6.The Struts 2 filter performs which of the following tasks? 1. Installation of the Action class 2.

The execute () method of the action class defines business logic implementations. ActionSupport class adds useful utilities to the class that extends it. Set of Interceptors are grouped into a stack known as Interceptor Stack. All of the above. 9.Which of the following annotation helps to set the path of the action URL? It is placed before the action class and it applies to all actions defined in the class, even if the fully qualified URLs are not supplied. @Namespace @Result @Results @ParentPackage 10.Which of the following statements are correct related to OGNL and Annotations? OGNL is an expression and binding language that is used for getting and setting the properties of the Java objects. Annotations acts as an alternative to HTML and Java properties configuration file. Action Annotations are available when the framework scans the classpath for action classes. Lifecycle callback annotations are invoked at any time during the processing of an action. 11.Which of the following are the features of the new unified Expression Language? Deferred evaluation of expression Support expressions that can set values and invoke methods Provides a pluggable API for resolving expressions All of the above. 12.By introducing the new feature by JSF, improvements have been made in which of the following areas? Set of standard converter messages Addition of requiredMessage, converterMessage, and validatorMessage attribute for input components. Displaying the error message using the input component name with the help of label attribute added to the input components All of the above. 13.Which of the following statements are correct about the 'label' attribute? In JSF 2.1, the label attribute have been introduced with the input components. The label attribute can accept literal or value expressions. The Literal or value expressions accepted by label attribute is prefixed before the components error message. All of the above. 14.Which of the following statements are correct? EL allows developers to use simple expressions to dynamically access data from JavaBeans components. EL supports only deferred evaluation. A value expression can either yield a value or set a value and can be used for both read and write. In immediate evaluation, the expression is evaluated immediately. 15.Which of the following statements are correct? Method expression invokes as arbitrary private method of an arbitrary object by passing a specified set of parameters and returning results from the calling method. JSTL is a part of Java EE 5 platform. JSF 1.2 includes a set of messages for standard converters. The requiredMessage, converterMessage, or the validatorMessage attribute of the input components are used to provide custom error messages.
