A method defined in the home interface and invoked by a client to locate an entity bean.
Industry:Computer
Small, fast, hardware-controlled memory that acts as a buffer between a processor and main memory. Cache contains a copy of the most recently used memory locations--addresses and contents--of instructions and data. Every address reference goes first to cache. If the desired instruction or data is not in cache, a cache miss occurs. The contents are fetched across the bus from main memory into the CPU register specified in the instruction being executed and a copy is also written to cache. It is likely that the same location will be used again soon, and, if so, the address is found in cache, resulting in a cache hit. If a write to that address occurs, the hardware not only writes to cache, but can also generate a write-through to main memory.

Industry:Computer
A messaging system in which clients address messages to a specific node in a content hierarchy, called a topic.

Industry:Computer
A medium that can retain information for subsequent retrieval. The term is most frequently used for referring to a computer's internal storage that can be directly addressed by machine instructions. See also cache, distributed memory, shared memory.
Industry:Computer
A mechanism that allows a component to be customized without the need to access or change the component's source code. A container implements the component's naming environment and provides it to the component as a JNDI naming context. 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.
Industry:Computer
Provides the services and management functions required to support transaction demarcation, transactional resource management, synchronization, and transaction context propagation.
