This classification includes the basic functionality for operating 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 as well as functionality that is unique to 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 the functionality. The Application Server functionality guide manuals have been arranged according to this classification.

The following is an overview of each classification:

• Functionality for executing Web applications (Web containers)
  This classification includes the Web container functionality that serves as an execution platform for Web applications and the functionality executed by linking Web containers and Web servers.
  
• Functionality for executing 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 functionality)
  This classification includes the functionality that can be used in the Web applications and the Enterprise Beans that run Web containers and EJB containers respectively.
  

This classification corresponds to the functionality that serves as an execution environment and a development environment for Web Services.

Application Server provides the following engines:

• JAX-WS engine, which binds SOAP Messages according to the JAX-WS specifications
• JAX-RS engine, which binds RESTful HTTP messages according to the JAX-RS specifications

This classification includes functionality that is expanded uniquely for Application Server unique . This classification also includes the functionality executed by using non-J2EE server processes such as a batch server, CTM, or database.

Various Application Server functionality is expanded to improve the reliability of the system and to execute stable operations. Furthermore, the functionality is also expanded to operate applications other than J2EE applications (batch applications) in a Java environment.

This classification includes the functionality for maintaining security of a system centered around Application Server. This classification comprises functionalities such as authentication functionality for preventing access by unauthorized users and encryption functionality for preventing information leakage in the communication channel.
