118. What is J2EE application
Any deployable unit of J2EE functionality. This can be a single J2EE module or a group of modules packaged into an EAR file along with a J2EE application deployment descriptor. J2EE applications are typically
engineered to be distributed across multiple computing tiers.
119. What is J2EE component
A self-contained functional software unit supported by a container and configurable at deployment time. The J2EE specification defines the following J2EE components: Application clients and applets are components that run on the client. Java servlet and JavaServer Pages (JSP) technology components are Web components that run on the server. Enterprise JavaBeans (EJB) components (enterprise beans) are
business components that run on the server. J2EE components are written in the Java programming language and are compiled in the same way as any program in the language. The difference between J2EE
components and “standard” Java classes is that J2EE components are assembled into a J2EE application, verified to be well formed and in compliance with the J2EE specification, and deployed to production, where they are run and managed by the J2EE server or client container.
120. What is J2EE module
A software unit that consists of one or more J2EE components of the same container type and one deployment descriptor of that type. There are four types of modules: EJB, Web, application client, and resource adapter. Modules can be deployed as stand-alone units or can be assembled into a J2EE application.
121. What is J2EE product
An implementation that conforms to the J2EE platform specification.
122. What is J2EE product provider
A vendor that supplies a J2EE product.
123. What is J2EE server
The runtime portion of a J2EE product. A J2EE server provides EJB or Web containers or both.
124. What is J2ME
Abbreviate of Java 2 Platform, Micro Edition.
125. What is J2SE
Abbreviate of Java 2 Platform, Standard Edition.
126. What is JAR
Java archive. A platform-independent file format that permits many files to be aggregated into one file.
127. What is Java 2 Platform, Enterprise Edition (J2EE)
An environment for developing and deploying enterprise applications. The J2EE platform consists of a set of services, application programming interfaces (APIs), and protocols that provide the functionality for
developing multitiered, Web-based applications.
128. What is Java 2 Platform, Micro Edition (J2ME)
A highly optimized Java runtime environment targeting a wide range of consumer products, including pagers, cellular phones, screen phones, digital set-top boxes,and car navigation systems.
129. What is Java 2 Platform, Standard Edition (J2SE)
The core Java technology platform.
130. What is Java API for XML Processing (JAXP)
An API for processing XML documents. JAXP leverages the parser standards SAX and DOM so that you can choose to parse your data as a stream of events or to build a tree-structured representation of it. JAXP
supports the XSLT standard, giving you control over the presentation of the data and enabling you to convert the data to other XML documents or to other formats, such as HTML. JAXP provides namespace support, allowing you to work with schema that might otherwise have naming conflicts.
131. What is Java API for XML Registries (JAXR)
An API for accessing various kinds of XML registries.
132. What is Java API for XML-based RPC (JAX-RPC)
An API for building Web services and clients that use remote procedure calls and XML .
133. What is Java IDL
A technology that provides CORBA interoperability and connectivity capabilities for the J2EE platform. These capabilities enable J2EE pplications to invoke operations on remote network services using the Object Management Group IDL and IIOP.
134. What is Java Message Service (JMS)
An API for invoking operations on enterprise messaging systems.
135. What is Java Naming and Directory Interface (JNDI)

143. What is JavaServer Faces event and listener model
A mechanism for determining how events emitted by JavaServer Faces UI components are handled. This model is based on the JavaBeans component event and listener model.
144. What is JavaServer Faces _expression language
A simple _expression language used by a JavaServer Faces UI component tag attributes to bind the associated component to a bean property or to bind the associated component’s value to a method or an
external data source, such as a bean property. Unlike JSP EL expressions, JavaServer Faces EL expressions are evaluated by the JavaServer Faces implementation rather than by the Web container.
145. What is JavaServer Faces navigation model
A mechanism for defining the sequence in which pages in a JavaServer Faces application are displayed.
147. What is JavaServer Faces UI component
A user interface control that outputs data to a client or allows a user to input data to a JavaServer Faces application.
