Abstract:
1. A method comprising: creating a Custom Class Loader from a Base Class Loader in a JAVA™ environment, wherein the Custom Class Loader is able to load JAVA™ class files either using a JAVA™ “import” mechanism or a JAVA™ Class.forName( ) mechanism, wherein the JAVA™ environment operates within an IBM™ 4690 Operating System environment, and wherein the Custom Class Loader operates in a first Point Of Sale (POS) device that is coupled to a controller; using the Custom Class Loader to dynamically load JAVA™ Classes from the controller to the first POS device, wherein the first POS device requests the JAVA™ Classes in response to a request from an application running on the first POS device, wherein the first POS device is coupled to other POS devices, the other POS devices including a second POS device and a third POS device; upon an interruption in communication between the controller and the first POS device, sending a request from the first POS device to the other POS devices requesting the JAVA™ Class; storing in the second POS device a record of JAVA™ Classes stored in the third POS device; sending a request for the JAVA™ Class from the first POS device to the second POS device, wherein the requested JAVA™ Class is not stored in the second POS device, and wherein the requested JAVA™ Class is stored in the third POS device; and in response to the second POS device not having the requested JAVA™ Class, sending the first POS device information identifying the third POS device as having the requested JAVA™ Class.
