Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
A system-level software driver that is used by an EJB container or an application client to connect to an enterprise information system. A resource adapter typically is specific to an enterprise information system. It is available as a library and is used within the address space of the server or client using it. A resource adapter plugs in to a container. The application components deployed on the container then use the client API (exposed by the adapter) or tool-generated high-level abstractions to access the underlying enterprise information system. The resource adapter and EJB container collaborate to provide the underlying mechanisms-transactions, security, and connection pooling-for connectivity to the enterprise information system.
Industry:Computer
A set of properties associated with a principal. Security attributes can be associated with a principal by an authentication protocol or by a J2EE product provider or both.
Industry:Computer
A set of formatting instructions that apply to the nodes selected by an XPath expression.
Industry:Computer
A set of auditing options that an administrator can enable or disable. These options include which events will be recorded and whether to record certain kinds of audit data. The options also include whether to suspend audible actions when the audit trail is full. This term is used in XSCF firmware.
Industry:Computer
The function performed by a party in the development and deployment phases of an application developed using J2EE technology. The roles are application component provider, application assembler, deployer, J2EE product provider, EJB container provider, EJB server provider, Web container provider, Web server provider, tool provider, and system administrator.
Industry:Computer
The framework events of a J2EE component's existence. Each type of component has defining events that mark its transition into states in which it has varying availability for use. For example, a servlet is created and has its init method called by its container before invocation of its service method by clients or other servlets that require its functionality. After the call of its init method, it has the data and readiness for its intended use. The servlet's destroy method is called by its container before the ending of its existence so that processing associated with winding up can be done and resources can be released. The init and destroy methods in this example are callback methods. Similar considerations apply to the life cycle of all J2EE component types: enterprise beans, Web components (servlets or JSP pages), applets, and application clients.
Industry:Computer
The execution of two or more active threads or processes in parallel. On a uniprocessor apparent concurrence is accomplished by rapidly switching between threads. On a multiprocessor system true parallel execution can be achieved. See also asynchronous control, multiprocessor system, thread.
Industry:Computer
A self-contained functional software unit supported by a container and configurable at deployment time. The J2EE specification defines the following J2EE components:
*Application clients and applets are components that run on the client.
*Java servlet and JavaServer Pages (JSP) technology components are Web components that run on the server.
*Enterprise JavaBeans (EJB) components (enterprise beans) are business components that run on the server.
J2EE components are written in the Java programming language and are compiled in the same way as any program in the language. The difference between J2EE components and "standard" Java classes is that J2EE components are assembled into a J2EE application, verified to be well formed and in compliance with the J2EE specification, and deployed to production, where they are run and managed by the J2EE server or client container.
