Information processing apparatus and method

An information processing method of a first computer in a system including a plurality of computers each connected to a network, a second computer executing a directory service program, the directory service program including a remote reference representing a network address of each of the plurality of computers, comprising:

• executing a server program described as an object-oriented language executed by a platform independent machine language;
• creating a remote reference of the first computer when the server program is generated in the first computer, the remote reference including the network address and a port number of the first computer;
• registering the remote reference in the directory service program of the second computer, a third computer referring to the remote reference in the second computer through the network to access the server program;
• monitoring a chance of a network address of the first computer while the server program is operating;
• acquiring a new network address of the first computer when the change of the network address of the first computer is detected;
• updating the network address of the remote reference in the second computer by using the new network address;
• storing a stub class describing a procedure necessary for the third computer to process the server program received from the first computer;
• and
• storing a location address of the stub class in a codebase.

A computer program product comprising:

• a computer readable program code embodied in said product for causing a first computer in a system including a plurality of computers each connected to a network, a second computer executing a directory service program, the directory service program including a remote reference representing a network address of each of the plurality of computers, said computer readable program code having:
• a first program code to execute a server program described as an object-oriented language executed by a platform independent machine language;
• a second program code to create a remote reference of the first computer when the server program is generated in the first computer, the remote reference including the network address and a port number of the first computer;
• a third program code to register the remote reference in the directory service program of the second computer, a third computer referring to the remote reference in the second computer through the network to access the server program;
• a fourth program code to monitor a change of a network address of the first computer while the service program is operating;
• a fifth program code to acquire a new network address of the first computer when the change of the network address of the first computer is detected;
• a sixth program code to update the network address of the remote reference in the second computer by using the new network address;
• a seventh program code to store a stub class describing a procedure necessary for the third computer to process the server program received from the first computer;
• and
• an eighth program code to store a location address of the stub class in a codebase.
