4.Which of the following statements are correct?


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.

7.Which of the following value for the debug parameter
displays an OGNL console to test OGNL expressions against
the value stack?


xml
console
command
All of the above.

8.Which of the following are correct statements?


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.
