This functionality includes the basic functionality for operating the applications (J2EE applications). This functionality is mainly the J2EE server functionality.

Application Server provides a Java EE 6-compliant J2EE server. The J2EE server provides functionality that is compliant with the standard specifications and is independent of Application Server.

The basic development functionality can be further classified into three types according to the types of the J2EE applications for which you use functionality. The manuals for the Application Server function guide have been divided according to this classification.

The following is an overview of each classification:

• Functionality for executing the Web applications (Web containers)
  This classification includes the Web container functionality that serves as the execution platform for Web applications and functionality executed by linking Web containers and Web servers.
  
• Functionality for executing the Enterprise Beans (EJB containers)
  This classification includes the EJB container functionality that serves as a platform for executing Enterprise Beans. This classification also includes the EJB client functionality for invoking Enterprise Beans.
  
• Functionality used in both Web applications and Enterprise Beans (Container common function)
  This classification includes functionality that can be used in the Web applications and the Enterprise Beans operating Web containers and EJB containers respectively.
  

This classification includes the functionality that can be used as the execution environment and development environment for Web Services.

Application Server provides the following engines:

• The JAX-WS engine that performs binding of SOAP messages in accordance with the JAX-WS specifications
• The JAX-RS engine that performs the binding of RESTful HTTP messages in accordance with the JAX-RS specifications

This includes the functionality extended independently for Application Server. This also includes functionality implemented by using non-J2EE server processes such as a batch server, CTM, and database.

With Application Server, various functionality are extended to improve reliability of the system and to implement stable operations. Furthermore, functionality is also extended to operate applications other than J2EE applications (batch applications) in the Java environment.

The functionalities that ensure system security with a focus on Application Server fall into this category. This includes functionalities such as the authentication functionality to prevent access by unauthorized users and encryption functionality to prevent information leakage in communication paths.
