Patent ID: 8903704

Claim:
An information processing system, comprising: a platform development device including an application platform of an image forming device and a simulator which simulates one or more hardware functions including a printer, a copier, a facsimile machine, and a scanner of the image forming device; and an information processing device connected to the platform development device via a network, the information processing device including a platform emulator that emulates the application platform of the image forming device, the platform emulator including: an implementing information acquiring part to receive a list of information items of interfaces implemented on the application platform in the platform development device from the platform development device via the network and store the list of information items in an implementing information holding part; a determining part to determine, in response to an interface calling request from an application that uses the platform emulator, whether an interface is implemented in the platform development device based on the list of information items stored in the implementing information holding part; an emulator part to perform emulation of the interface called by the application when a result of the determination from the determining part indicates that the interface is not implemented in the platform development device, and send a result of the emulation to the application; and an external calling part to receive a request of calling of the interface from the emulator part when the determination result indicates that the interface is implemented in the platform development device, and send the request of calling of the interface to the platform development device.
