Sun Java System Application Server (Application Server) provides a J2EE compatible platform for developing and delivering server-side Java applications and web services. Key features include scalable transaction management, container-managed persistence runtime, web services performance, clustering, high availability session state, security, and integration capabilities.
Application Server includes the following subcomponents:
Domain Administration Server. Provides server-side administration functions, such as managing and configuring Application Server and deploying J2EE components and applications.
Application Server Node Agent. A lightweight process that runs on every machine that hosts server instances and performs a number of administrative tasks, including stopping, starting, and restarting server instances.
Command Line Administration Tool. Provides command-line administration clients that enable you to manage and configure Application Server installations and hosted applications. The tool also assists with deploying applications.
Load Balancing Plug-in. Used to evenly distribute the workload among multiple Application Server instances (either stand-alone or clustered), thereby increasing the overall throughput of the system. Also used to enable requests to fail over from one server instance to another.
Sample Applications. Installed with the full installation of Application Server.
