150. What is Java Server 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.
149. What is Java Server Faces validation model
A mechanism for validating the data a user inputs to aJavaServer Faces UI component.
148. What is Java Server Faces UI component class
A Java Server Faces class that defines the behavior and properties of a Java Server Faces UI component.
147. What is Java Server Faces UI component
A user interface control that outputs data to a client allows a user to input data to a Java Server Faces application.
145. What is Java Server Faces navigation model
A mechanism for defining the sequence in which pages in a Java Server Faces application are displayed.
144. What is Java Server Faces _expression language
A simple _expression language used by a Java Server 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 EL expressions, Java Server Faces EL expressions are evaluated by the Java Server Faces implementation rather than by the Web container.

138. What is Java Transaction Service (JTS)
Specifies the implementation of a transaction manager that supports JTA and implements the Java mapping of the Object Management Group Object Transaction Service1.1 specification at the level below the API.
137. What is Java Transaction API (JTA)
An API that allows applications and J2EE servers to access transactions.
136. What is Java Secure Socket Extension (JSSE)
A set of packages that enable secure Internet communications.
135. What is Java Naming and Directory Interface (JNDI)
An API that provides naming and directory functionality.
134. What is Java Message Service (JMS)
An API for invoking operations on enterprise messaging systems.
133. What is Java IDL
A technology that provides CORBA interoperability and connectivity capabilities for the J2EE platform. These capabilities enable J2EE applications to invoke operations on remote network services using the Object Management Group IDL and IIOP.
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
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.
128. What is Java 2 Platform, Micro Edition (J2ME)
