<p>A system for patching an applet and a method thereof are provided to call out a function between applets through a client SIO interface unit. A patch applet(120) corresponds to a client applet(110), and a JCRE(Java Card Runtime Environment)(130) calls out a function defined by the patch applet and the client applet. A function realizing unit(113) realizes a patch possible function and a function of the client applet or the patch applet, and a client SIO interface unit(111) shares a function with the patch applet. A patch SIO interface unit(121) shares a function with the client applet.</p> |
