Solaris threads are implemented as a user-level library, using the kernel's threads of control, that are called light-weight processes (LWPs). In the Solaris environment, a process is a collection of LWPs that share memory. Each LWP has the scheduling priority of a UNIX process and shares the resources of that process. LWPs coordinate their access to the shared memory by using synchronization mechanisms such as locks. An LWP can be thought of as a virtual CPU that executes code or system calls. The threads library schedules threads on a pool of LWPs in the process, in much the same way as the kernel schedules LWPs on a pool of processors. Each LWP is independently dispatched by the kernel, performs independent system calls, incurs independent page faults, and runs in parallel on a multiprocessor system. The LWPs are scheduled by the kernel onto the available CPU resources according to their scheduling class and priority.

A method of messaging that includes blocking until a response is received.

Software that provides services to an EJB container. For example, an EJB container typically relies on a transaction manager that is part of the EJB server to perform the two-phase commit across all the participating resource managers. The J2EE architecture assumes that an EJB container is hosted by an EJB server from the same vendor, so it does not specify the contract between these two entities. An EJB server can host one or more EJB containers.

A method of an enterprise bean that implements the business logic or rules of an application.

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.
Industry:Computer
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.
