What is DTD
Document type definition. An optional part of the XML document prolog, as specified by the XML standard. The DTD specifies
constraints on the valid tags and tag sequences that can be in the document. The DTD has a number of shortcomings, however,
and this has led to various schema proposals. For example, the DTD entry says that the XML
element called username contains parsed character data-that is, text alone, with no other structural elements under it. The
DTD includes both the local subset, defined in the current file, and the external subset, which consists of the definitions
contained in external DTD files that are referenced in the local subset using a parameter entity.

An object that can transform the header or content (or both) of a request or response. Filters differ from Web components in
that they usually do not themselves create responses but rather modify or adapt the requests for a resource, and modify or
adapt responses from a resource. A filter should not have any dependencies on a Web resource for which it is acting as a
filter so that it can be composable with more than one type of Web resource.

An object that identifies an enterprise bean. A client can serialize the handle and then later deserialize it to obtain a
reference to the enterprise bean.
What is home handle
An object that can be used to obtain a reference to the home interface. A home handle can be serialized and written to stable
storage and deserialized to obtain the reference.
What is home interface

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.
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.

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.
What is life cycle (JavaServer Faces)

What is mutual authentication
An authentication mechanism employed by two parties for the purpose of proving each other's identity to one another.
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
What is naming context
A set of associations between unique, atomic, people-friendly identifiers and objects.
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.

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.
<
What is normalization
The process of removing redundancy by modularizing, as with subroutines, and of removing superfluous differences by reducing them to a common denominator. For example, line endings from different systems are normalized by reducing them to a single new line, and multiple whitespace characters are normalized to one space.
What is North American Industry Classification System (NAICS)
A system for classifying business establishments based on the processes they use to produce goods or services.
What is notation

What is request-response messaging
A method of messaging that includes blocking until a response is received.
What is resource adapter
A system-level software driver that is used by an EJB container or an application client to connect to an enterprise information system. A resource adapter typically is specific to an enterprise information system. It is available as a library and is used within the address space of the server or client using it. A resource adapter plugs in to a container. The application components deployed on the container then use the client API (exposed by the adapter) or tool-generated high-level abstractions to access the underlying enterprise information system. The resource adapter and EJB container collaborate to provide the underlying mechanisms-transactions, security, and connection pooling-for connectivity to the enterprise information system.
What is resource adapter module
A deployable unit that contains all Java interfaces, classes, and native libraries, implementing a resource adapter along with the resource adapter deployment descriptor.
What is resource manager
Provides access to a set of shared resources. A resource manager participates in transactions that are externally controlled and coordinated by a transaction manager. A resource manager typically is in a different address space or on a different machine from the clients that access it. Note: An enterprise information system is referred to as a resource manager when it is mentioned in the context of resource and transaction management.
What is resource manager connection
An object that represents a session with a resource manager.

The process of associating the groups or principals (or both), recognized by the container with security roles specified in the deployment descriptor. Security roles must be mapped by the deployer before a component is installed in the server.
What is role (security)
An abstract logical grouping of users that is defined by the application assembler. When an application is deployed, the roles are mapped to security identities, such as principals or groups, in the operational environment.
In the J2EE server authentication service, a role is an abstract name for permission to access a particular set of resources. A role can be compared to a key that can open a lock. Many people might have a copy of the key; the lock doesn't care who you are, only that you have the right key.
What is rollback
The point in a transaction when all updates to any resources involved in the transaction are reversed.
What is root
The outermost element in an XML document. The element that contains all other elements.

An event-driven interface in which the parser invokes one of several methods supplied by the caller when a parsing event occurs. Events include recognizing an XML tag, finding an error, encountering a reference to an external entity, or processing a DTD specification.
What is schema
A database-inspired method for specifying constraints on XML documents using an XML-based language. Schemas address deficiencies in DTDs, such as the inability to put constraints on the kinds of data that can occur in a particular field. Because schemas are founded on XML, they are hierarchical. Thus it is easier to create an unambiguous specification, and it is possible to determine the scope over which a comment is meant to apply.
What is Secure Socket Layer (SSL)
A technology that allows Web browsers and Web servers to communicate over a secured connection.
What is security attributes
A set of properties associated with a principal. Security attributes can be associated with a principal by an authentication protocol or by a J2EE product provider or both.

What is security permission set
The minimum set of security permissions that a J2EE product provider must provide for the execution of each component type.
What is security policy domain
A scope over which security policies are defined and enforced by a security administrator. A security policy domain has a collection of users (or principals), uses a well-defined authentication protocol or protocols for authenticating users (or principals), and may have groups to simplify setting of security policies.
What is security role
See role (security).
What is security technology domain
A scope over which the same security mechanism is used to enforce a security policy. Multiple security policy domains can exist within a single technology domain.
What is security view

What is servlet container
A container that provides the network services over which requests and responses are sent, decodes requests, and formats responses. All servlet containers must support HTTP as a protocol for requests and responses but can also support additional request-response protocols, such as HTTPS.
What is servlet container, distributed
A servlet container that can run a Web application that is tagged as distributable and that executes across multiple Java virtual machines running on the same host or on different hosts.
What is servlet context
An object that contains a servlet's view of the Web application within which the servlet is running. Using the context, a servlet can log events, obtain URL references to resources, and set and store attributes that other servlets in the context can use.
What is servlet mapping
Defines an association between a URL pattern and a servlet. The mapping is used to map requests to servlets.
What is session
An object used by a servlet to track a user's interaction with a Web application across multiple HTTP requests.
What is session bean
An enterprise bean that is created by a client and that usually exists only for the duration of a single client-server session. A session bean performs operations, such as calculations or database access, for the client. Although a session bean can be transactional, it is not recoverable should a system crash occur. Session bean objects either can be stateless or can maintain conversational state across methods and transactions. If a session bean maintains state, then the EJB container manages this state if the object must be removed from memory. However, the session bean object itself must manage its own persistent data.
What is SGML
Standard Generalized Markup Language. The parent of both HTML and XML. Although HTML shares SGML's propensity for embedding presentation information in the markup, XML is a standard that allows information content to be totally separated from the mechanisms for rendering that content.
What is SOAP
Simple Object Access Protocol. A lightweight protocol intended for exchanging structured information in a decentralized, distributed environment. It defines, using XML technologies, an extensible messaging framework containing a message construct that can be exchanged over a variety of underlying protocols.

What is stateless session bean
A session bean with no conversational state. All instances of a stateless session bean are identical.
What is system administrator
The person responsible for configuring and administering the enterprise's computers, networks, and software systems.
What is tag
In XML documents, a piece of text that describes a unit of data or an element. The tag is distinguishable as markup, as opposed to data, because it is surrounded by angle brackets (< and >). To treat such markup syntax as data, you use an entity reference or a CDATA section.
What is template
A set of formatting instructions that apply to the nodes selected by an XPath expression.
What is tool provider
An organization or software vendor that provides tools used for the development, packaging, and deployment of J2EE applications.
What is topic
See publish-subscribe messaging system.

An atomic unit of work that modifies data. A transaction encloses one or more program statements, all of which either complete or roll back. Transactions enable multiple users to access the same data concurrently.
What is transaction attribute
A value specified in an enterprise bean's deployment descriptor that is used by the EJB container to control the transaction scope when the enterprise bean's methods are invoked. A transaction attribute can have the following values: Required, RequiresNew, Supports, NotSupported, Mandatory, or Never.
What is transaction isolation level
The degree to which the intermediate state of the data being modified by a transaction is visible to other concurrent transactions and data being modified by other transactions is visible to it.
What is transaction manager
Provides the services and management functions required to support transaction demarcation, transactional resource management, synchronization, and transaction context propagation.
What is Unicode
A standard defined by the Unicode Consortium that uses a 16-bit code page that maps digits to characters in languages around the world.

A schema that classifies and identifies commodities. It is used in sell-side and buy-side catalogs and as a standardized account code in analyzing expenditure.
What is unparsed entity
A general entity that contains something other than XML. By its nature, an unparsed entity contains binary data.
What is URI
Uniform resource identifier. A globally unique identifier for an abstract or physical resource. A URL is a kind of URI that specifies the retrieval protocol (http or https for Web applications) and physical location of a resource (host name and host-relative path). A URN is another type of URI.
What is URL
Uniform resource locator. A standard for writing a textual reference to an arbitrary piece of data in the World Wide Web. A URL looks like this: protocol://host/localinfo where protocol specifies a protocol for fetching the object (such as http or ftp), host specifies the Internet name of the targeted host, and localinfo is a string (often a file name) passed to the protocol handler on the remote host.
What is URL path
The part of a URL passed by an HTTP request to invoke a servlet. A URL path consists of the context path + servlet path + path info, where Context path is the path prefix associated with a servlet context of which the servlet is a part. If this context is the default context rooted at the base of the Web server's URL namespace, the path prefix will be an empty string. Otherwise, the path prefix starts with a / character but does not end with a / character.
Servlet path is the path section that directly corresponds to the mapping that activated this request. This path starts with a / character.
Path info is the part of the request path that is not part of the context path or the servlet path.
What is URN
Uniform resource name. A unique identifier that identifies an entity but doesn't tell where it is located. A system can use a URN to look up an entity locally before trying to find it on the Web. It also allows the Web location to change, while still allowing the entity to be found.
What is user data constraint
Indicates how data between a client and a Web container should be protected. The protection can be the prevention of tampering with the data or prevention of eavesdropping on the data.
What is user (security)
An individual (or application program) identity that has been authenticated. A user can have a set of roles associated with that identity, which entitles the user to access all resources protected by those roles.
What is valid
A valid XML document, in addition to being well formed, conforms to all the constraints imposed by a DTD. It does not contain any tags that are not permitted by the DTD, and the order of the tags conforms to the DTD's specifications.
What is validating parser
A parser that ensures that an XML document is valid in addition to being well formed. See also parser.
What is value-binding expression
A JavaServer Faces EL expression that refers to a property of a backing bean. A component tag uses this expression to bind the associated component's value or the component instance to the bean property. If the component tag refers to the property via its value attribute, then the component's value is bound to the property. If the component tag refers to the property via its binding attribute then the component itself is bound to the property.
What is virtual host
Multiple hosts plus domain names mapped to a single IP address.
What is W3C
World Wide Web Consortium. The international body that governs Internet standards. Its Web site is http://www.w3.org/.
What is WAR file
Web application archive file. A JAR archive that contains a Web module.
What is warning
A SAX parser warning is generated when the document's DTD contains duplicate definitions and in similar situations that are not necessarily an error but which the document author might like to know about, because they could be. See also fatal error, error.
What is Web application
An application written for the Internet, including those built with Java technologies such as JavaServer Pages and servlets, as well as those built with non-Java technologies such as CGI and Perl.
What is Web application, distributable
A Web application that uses J2EE technology written so that it can be deployed in a Web container distributed across multiple Java virtual machines running on the same host or different hosts. The deployment descriptor for such an application uses the distributable element.
What is Web component
A component that provides services in response to requests; either a servlet or a JSP page.
What is Web container
A container that implements the Web component contract of the J2EE architecture. This contract specifies a runtime environment for Web components that includes security, concurrency, life-cycle management, transaction, deployment, and other services. A Web container provides the same services as a JSP container as well as a federated view of the J2EE platform APIs. A Web container is provided by a Web or J2EE server.
What is Web container, distributed
A Web container that can run a Web application that is tagged as distributable and that executes across multiple Java virtual machines running on the same host or on different hosts.
What is Web container provider
A vendor that supplies a Web container.
What is Web module
A deployable unit that consists of one or more Web components, other resources, and a Web application deployment descriptor contained in a hierarchy of directories and files in a standard Web application format.
What is Web resource
A static or dynamic object contained in a Web application that can be referenced by a URL.
What is Web resource collection
A list of URL patterns and HTTP methods that describe a set of Web resources to be protected.
What is Web server
Software that provides services to access the Internet, an intranet, or an extranet. A Web server hosts Web sites, provides support for HTTP and other protocols, and executes server-side programs (such as CGI scripts or servlets) that perform certain functions. In the J2EE architecture, a Web server provides services to a Web container. For example, a Web container typically relies on a Web server to provide HTTP message handling. The J2EE architecture assumes that a Web container is hosted by a Web server from the same vendor, so it does not specify the contract between these two entities. A Web server can host one or more Web containers.
What is Web server provider
A vendor that supplies a Web server.
What is Web service
An application that exists in a distributed environment, such as the Internet. A Web service accepts a request, performs its function based on the request, and returns a response. The request and the response can be part of the same operation, or they can occur separately, in which case the consumer does not need to wait for a response. Both the request and the response usually take the form of XML, a portable data-interchange format, and are delivered over a wire protocol, such as HTTP.
What is well-formed
An XML document that is syntactically correct. It does not have any angle brackets that are not part of tags, all tags have an ending tag or are themselves self-ending, and all tags are fully nested. Knowing that a document is well formed makes it possible to process it. However, a well-formed document may not be valid. To determine that, you need a validating parser and a DTD.
What is Xalan
An interpreting version of XSLT.
What is XHTML
An XML look-alike for HTML defined by one of several XHTML DTDs. To use XHTML for everything would of course defeat the purpose of XML, because the idea of XML is to identify information content, and not just to tell how to display it. You can reference it in a DTD, which allows you to say, for example, that the text in an element can contain etc tags rather than being limited to plain text.
What is XLink
The part of the XLL specification that is concerned with specifying links between documents.
What is XLL
The XML Link Language specification, consisting of XLink and XPointer.
What is XML
Extensible Markup Language. A markup language that allows you to define the tags (markup) needed to identify the content, data, and text in XML documents. It differs from HTML, the markup language most often used to present information on the Internet. HTML has fixed tags that deal mainly with style or presentation. An XML document must undergo a transformation into a language with style tags under the control of a style sheet before it can be presented by a browser or other presentation mechanism. Two types of style sheets used with XML are CSS and XSL. Typically, XML is transformed into HTML for presentation. Although tags can be defined as needed in the generation of an XML document, a document type definition (DTD) can be used to define the elements allowed in a particular type of document. A document can be compared by using the rules in the DTD to determine its validity and to locate particular elements in the document. A Web services application's J2EE deployment descriptors are expressed in XML with schemas defining allowed elements. Programs for processing XML documents use SAX or DOM APIs.
What is XML registry
See registry.
What is XML Schema
The W3C specification for defining the structure, content, and semantics of XML documents.
What is XPath
An addressing mechanism for identifying the parts of an XML document.
What is XPointer
The part of the XLL specification that is concerned with identifying sections of documents so that they can be referenced in links or included in other documents.
What is XSL
Extensible Stylesheet Language. A standard that lets you do the following:
Specify an addressing mechanism, so that you can identify the parts of an XML document that a transformation applies to (XPath).
Specify tag conversions, so that you can convert XML data into different formats (XSLT).
Specify display characteristics, such page sizes, margins, and font heights and widths, as well as the flow objects on each page. Information fills in one area of a page and then automatically flows to the next object when that area fills up. That allows you to wrap text around pictures, for example, or to continue a newsletter article on a different page (XSL-FO).
What is XSL-FO
A subcomponent of XSL used for describing font sizes, page layouts, and how information flows from one page to another.
What is XSLT
XSL Transformations. An XML document that controls the transformation of an XML document into another XML document or HTML. The target document often has presentation-related tags dictating how it will be rendered by a browser or other presentation mechanism. XSLT was formerly a part of XSL, which also included a tag language of style flow objects.
What is XSLTC
A compiling version of XSLT.
