1.1.1 Functionality as an application execution platform

This functionality works as a platform for executing online businesses and batch businesses implemented as the applications. You choose functionality that you want to use according to the intended use of a system and your requirements.

You must determine whether you want to use functionality that serves as the execution platform for the applications, even before you perform the system building or application development.

The following are the classification-wise descriptions of functionality that serve as the application execution platform:

Organization of this subsection
(1) Basic functionality to operate applications (basic development functions)
(2) Functionality for developing Web Services
(3) Application Server independent functionality extended for improving reliability and performance (expansion functionality)
(4) Functionality for ensuring the security of a system (security management functionality)

(1) Basic functionality to operate applications (basic development functions)

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:

(2) Functionality for developing Web Services

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

The following engines are provided with Application Server:

(3) Application Server independent functionality extended for improving reliability and performance (expansion functionality)

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.

(4) Functionality for ensuring the security of a system (security management functionality)

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.
