This functionality 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 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 Application Server function guide have been separated 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 the Web containers and the Web servers.
  
• Functionality for executing the Enterprise Bean (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 the Enterprise Beans.
  
• Functions 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 running on the Web containers and the EJB containers respectively.
  

This includes the functionality for the execution and development environment of Web Services.

The following engines are provided with Application Server:

• JAX-WS engine that binds the SOAP messages in accordance with the JAX-WS specifications
• JAX-RS engine that binds the RESTful HTTP messages in accordance with the JAX-RS specifications

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

On 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.

This is the functionality used for ensuring the security of an Application Server-based system. This includes functionality such as the authentication functionality used for preventing unauthorized access and the encryption functionality used for preventing information leakage from communication channels.
