A synchronization mechanism for coordinating tasks even when data accesses are not involved. A barrier is analogous to a gate. Processors or threads operating in parallel reach the gate at different times, but none can pass through until all processors reach the gate. For example, suppose at the end of each day, all bank tellers are required to tally the amount of money that was deposited, and the amount that was withdrawn. These totals are then reported to the bank vice president, who must check the grand totals to verify debits equal credits. The tellers operate at their own speeds; that is, they finish totaling their transactions at different times. The barrier mechanism prevents tellers from leaving for home before the grand total is checked. If debits do not equal credits, all tellers must return to their desks to find the error. The barrier is removed after the vice president obtains a satisfactory grand total.

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 <name> should be interpreted according to your DTD rather than using the definition for an element <name> in a different DTD.

A standard extension mechanism for containers that provides connectivity to enterprise information systems. A connector is specific to an enterprise information system and consists of a resource adapter and application development tools for enterprise information system connectivity. The resource adapter is plugged in to a container through its support for system-level contracts defined in the Connector architecture.

A standard defined by the Unicode Consortium that uses a 16-bit code page that maps digits to characters in languages around the world. Because 16 bits covers 32,768 codes, Unicode is large enough to include all the world's languages, with the exception of ideographic languages that have a different character for every concept, such as Chinese. For more information, see http://www.unicode.org/.
Industry:Computer
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.
