METHOD AND DEVICE FOR CONTROLLING PERIPHERAL DEVICE BY JAVA APPLET, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a data control system capable of simply evading operation limit items formed in a Java applet. SOLUTION: A reader/writer(R/W) driver 122 is stored by a library format in a library storing area 121 for storing libraries started by a Java interpreter 110. In the case of interpreting a Java applet 41, the interpreter accesses the driver 122 from the area 121 in accordance with a library access code and controls a reader/writer 20 in accordance with the driver 122 through an I/O port 14 to operate data stored in an IC card 30.
