Question 1 :
What is JavaServer Pages (JSP) ?
An extensible Web technology that uses static data, JSP elements, and server-side Java objects to generate dynamic content for a client. Typically the static data is HTML or XML elements, and in many cases the client is a Web browser.

A language used to write expressions that access the properties of JavaBeans components. EL expressions can be used in static text and in any standard or custom tag attribute that can accept an expression.
Question 25 :
What is JSP page ?
A text-based document containing static text and JSP elements that describes how to process a request to create a response. A JSP page is translated into and handles requests as a servlet.
Question 26 :
What is JSP scripting element ?
A JSP declaration, scriptlet, or expression whose syntax is defined by the JSP specification and whose content is written according to the scripting language used in the JSP page. The JSP specification describes the syntax and semantics for the case where the language page attribute is "java".
Question 27 :
What is JSP scriptlet ?
A JSP scripting element containing any code fragment that is valid in the scripting language used in the JSP page. The JSP specification describes what is a valid scriptlet for the case where the language page attribute is "java".
Question 28 :
What is JSP standard action ?
An action that is defined in the JSP specification and is always available to a JSP page.
Question 29 :
What is JSP tag file ?
A source file containing a reusable fragment of JSP code that is translated into a tag handler when a JSP page is translated into a servlet.
Question 30 :
What is JSP tag handler ?
A Java programming language object that implements the behavior of a custom tag.
Question 31 :
What is JSP tag library ?
A collection of custom tags described via a tag library descriptor and Java classes.
Question 32 :

Abbreviate of JavaServer Pages Standard Tag Library.
Question 33 :
What is JTA ?
Abbreviate of Java Transaction API.
Question 34 :
What is JTS ?
Abbreviate of Java Transaction Service.
Question 35 :
What is keystore ?
A file containing the keys and certificates used for authentication
Question 36 :
What is life cycle (J2EE component) ?
The framework events of a J2EE component's existence. Each type of component has defining events that mark its transition into states in which it has varying availability for use. For example, a servlet is created and has its init method called by its container before invocation of its service method by clients or other servlets that require its functionality. After the call of its init method, it has the data and readiness for its intended use. The servlet's destroy method is called by its container before the ending of its existence so that processing associated with winding up can be done and resources can be released. The init and destroy methods in this example are callback methods. Similar considerations apply to the life cycle of all J2EE component types: enterprise beans, Web components (servlets or JSP pages), applets, and application clients.
Question 37 :
What is life cycle (JavaServer Faces) ?
A set of phases during which a request for a page is received, a UI component tree representing the page is processed, and a response is produced. During the phases of the life cycle: The local data of the components is updated with the values contained in the request parameters. Events generated by the components are processed. Validators and converters registered on the components are processed. The components' local data is updated to back-end objects. The response is rendered to the client while the component state of the response is saved on the server for future requests.
Question 38 :
What is local subset ?
That part of the DTD that is defined within the current XML file.
Question 39 :
What is managed bean creation facility ?
A mechanism for defining the characteristics of JavaBeans components used in a JavaServer Faces application.
Question 40 :
What is message ?
In the Java Message Service, an asynchronous request, report, or event that is created, sent, and consumed by an enterprise application and not by a human. It contains vital information needed to coordinate enterprise applications, in the form of precisely formatted data that describes specific business actions.
Question 41 :
What is message consumer ?
An object created by a JMS session that is used for receiving messages sent to a destination.
Question 42 :
What is message-driven bean ?
An enterprise bean that is an asynchronous message consumer. A message-driven bean has no state for a specific client, but its instance variables can contain state across the handling of client messages, including an open database connection and an object reference to an EJB object. A client accesses a message-driven bean by sending messages to the destination for which the bean is a message listener.
Question 43 :
What is message producer ?
An object created by a JMS session that is used for sending messages to a destination.
Question 44 :
What is mixed-content model ?
A DTD specification that defines an element as containing a mixture of text and one more other elements. The specification must start with #PCDATA, followed by diverse elements, and must end with the "zero-or-more" asterisk symbol (*).
Question 45 :
What is method-binding expression ?
A Java Server Faces EL expression that refers to a method of a backing bean. This method performs either event handling, validation, or navigation processing for the UI component whose tag uses the method-binding expression.
Question 46 :
What is method permission ?
An authorization rule that determines who is permitted to execute one or more enterprise bean methods.
Question 47 :
What is mutual authentication ?
An authentication mechanism employed by two parties for the purpose of proving each other's identity to one another.
Question 48 :
What is namespace ?
A standard that lets you specify a unique label for the set of element names defined by a DTD. A document using that DTD can be included in any other document without having a conflict between element names. The elements defined in your DTD are then uniquely identified so that, for example, the parser can tell when an element should be interpreted according to your DTD rather than using the definition for an element in a different DTD.
Question 49 :
What is naming context ?
A set of associations between unique, atomic, people-friendly identifiers and objects.
Question 50 :
What is naming environment ?
A mechanism that allows a component to be customized without the need to access or change the component's source code. A container implements the component's naming environment and provides it to the component as a JNDI naming context. Each component names and accesses its environment entries using the java:comp/env JNDI context. The environment entries are declaratively specified in the component's deployment descriptor.
