The present invention prepares the parameter conversion identification files as the definition information of parameter description for the execution environment setting files for use in a program development server and a connection test server, respectively. In the connection test server, a parameter conversion table is created on the basis of the parameter conversion identification files, and the execution environment parameters of the execution environment setting file acquired from the program development server are converted on the basis of the parameter conversion table to create an execution environment setting file suitable for its own apparatus. Using a location identification file, each file acquired from the program development server is copied into a designated directory to construct an execution environment for the connection test server.
