A process allowing communication between a java code and an executable software file which permits the java code to receive an access to the internal system resources of the user's computer. The java code is arranged to be configured as a server in the client's configuration, by means of the establishment of a server socket communication channel. Once established, that socket communication channel is used for allowing a full ordered, error-free communication between the java code and the local executable file, thereby allowing the java code to take profit of the internal system resources of the user's computer. Preferably, the java code is received by the user through an Internet/Intranet network as an applet which thus receives an effective and powerful access to the system resources of the user's machine.
