Abstract: The present invention relates to a method and system for dynamically loading program logic into an application. The method comprises the following steps. The client computer launches an application to issue a request to a server. The server receives the request and transfers a configuration file to the client computer based on the request. The configuration file comprises a program logic file name and a program logic file address. The program logic file address corresponds to a storage apparatus where the program logic file corresponding to the program logic file name is located. The program logic file comprises the program logic required to execute the application. The client computer receives the configuration file, links to the storage apparatus corresponding to the program logic file address and downloads the program logic file. The client computer executes the application in accordance with program logic in the program logic file.
