UDDI

(Universal Description, Discovery, and Integration) (n.) Provides worldwide registry of web services for discovery and integration.

Unicode

(n.) A 16-bit character set defined by ISO 10646 and the Unicode Consortium that maps digits to characters in languages around the world.

All source code in the Java programming environment is written in Unicode. For more information, see http://www.unicode.org/.

URL mapping

(n.) The process of mapping a document directory’s physical path name to a user-defined alias so that files within the directory need only refer to the directory’s alias instead of the file’s full physical path name. Instead of identifying a file as usr/JES/servers/docs/index.html, you could identify the file as /myDocs/index.html. This mapping provides additional security for a server by eliminating the need for users to know the physical location of server files.

URL path

(n.) The part of a URL passed by an HTTP request to invoke a servlet. A URL path consists of the context path, servlet path, and path info, as follows:

• The 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.

• The servlet path is the path section that directly corresponds to the mapping that activated this request. This path starts with a / character.

• The path info is the part of the request path that is not part of the context path or the servlet path.

user session

(n.) A series of user application interactions that are tracked by the server. Sessions maintain user state, persistent objects, and identity authentication.
