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.
Industry:Computer
A software unit that consists of one or more classes and an application client deployment descriptor.
Industry:Computer
The most popular protocol for maintaining cache coherency is called snooping. Cache controllers monitor or snoop on the bus to determine whether or not the cache contains a copy of a shared block.
For reads, multiple copies can reside in the cache of different processors, but because the processors need the most recent copy, all processors must get new values after a write. See also cache, competitive-caching, false sharing, write-invalidate, write-update.
For writes, a processor must have exclusive access to write to cache. Writes to unshared blocks do not cause bus traffic. The consequence of a write to shared data is either to invalidate all other copies or to update the shared copies with the value being written. See also cache, competitive-caching, false sharing, write-invalidate, write-update.

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.
Industry:Computer
The mechanism whereby security information needed for signing on to a resource is supplied by the container.
