(Graphical User Interfac
e) An X window system has been developed as a remote instruction processing method for the environment.

[0003] In addition, an applet (A
For example, a method of requesting a client, which is a user, to transfer processing contents such as pplet) from a remote location, or installing the processing contents is also considered. Further, a server that is a processing request source and a client that is a request destination individually prepare software for instruction processing and communication have been considered.

[0004]

However, with regard to some of the remote command processing described above, those using the X window system, for example, can display only a display processing part at a client located at another location. However, adopting UNIX or the like is a prerequisite for taking in the display processing software and displaying it on the client side. That is, there is a problem that this system is limited to only an environment in which an X window system such as a UNIX environment is mounted.

[0005] Further, a system for requesting a transfer of an applet owned by a server from a client has a problem that a large load is imposed on a network due to a large data capacity of the applet itself.

[0006] Further, in the case where the processing request source and the request destination individually prepare software related to instruction processing and communication, not only the development of an applet but also the study and development of a data communication method between the two are individually studied and developed. And there is a problem that the development cost increases.

The present invention has been made in view of the above circumstances, and separates an instruction processing main body portion and a specific function processing portion from each other.
It is an object of the present invention to provide a distributed processing environment system and a distributed processing environment method in which an instruction processing main body is left on a request destination machine and a specific function processing part can be processed by a request source machine.
