Method for updating chip card applications
First Claim
1. Method for loading a new application release allowing to an earlier application release into a computer device in a programming language using objects and permitting, among others, an introduction of additional classes, a class hierarchy modification and a definition of further fields and methods, said method comprising the steps of:
- computing, prior to that loading, a piece of information for matching the classes of said earlier application release to the classes of the new application release;
computing, prior to that loading, a piece of information for matching the static field identifiers of the earlier application release to the static field identifiers of the new application release;
linking said matching information to the new application release as loaded into the computer device;
using said matching information to modify the objects so that they point at the classes of the new application release and they use the new static field identifiers of the new application release.

Abstract
The invention relates to a method for enabling a new version of an application to be loaded onto a computer processing device. According to said method, information on the correspondence (I1, I3, I4, I6) between the classes (A to D) of the old version of the application and the classes (A to F) of the new version of the application, and information about correspondence between the static fields of the old version of the application and static fields of the new version of the application, is calculated prior to the loading. Said correspondence information is then associated in order to modify the objects in such a way that they point towards classes of the new version and use the new identifiers of the static fields of the new version of the application.
