摘要：A method and a system for decoupling a calling application from an externalapplication in a manufacturing execution system, wherein the calling application interacts
with the external application by requesting the execution of one or more externalmethods defined within the external application. First, the calling application obtainsthree lists from the external application, namely, the available external method listcontaining the ordered list of the available external methods, the usable parameter listcontaining the ordered list of the parameters usable by the external methods, and thesignature list containing the list of signatures of the external method. The term signatureindicated a coded way to define a method interface. The calling application requests acommand to call a given external method from the external application by performingthe following sub-steps: assigning, for the requested given method, a value to theposition index within the available method list; getting the signature of the given methodfrom the signature list by applying its position index; gathering, from the usableparameter list, the required parameters of the given method as indicated from itssignature; and generating the command to call the external method with its requiredparameters.
