Abstract
A method implemented by a Java Card device for updating a CAP file including at least one existing component on the Java Card device. The method includes: receiving from a terminal one or multiple first commands including an update file for updating the CAP file; determining at least one element type or location of at least one existing first element of the CAP file using type information or first location information included in the update file; searching the CAP file on the Java Card device for the at least one existing first element using the at least one determined element type or location; and if the at least one existing first element is found, replacing each of the at least one existing first element by one of at least one new first element included in the update file.
