Abstract:
A computer device (200) includes a deployment unit (220) which deploys an application program (100) into a runtime execution environment (203) based on configuration information from a plurality of configuration files (120), including at least one base configuration file (122) and one or more supplementary configuration files (123), wherein a merge unit (220) uses the one or more supplementary configuration files (123) to act upon and modify the configuration information provided in the base configuration file (122). A method of providing configuration files in a computer device (200) includes modifying configuration information provided in the base configuration file (122) using the one or more supplementary configuration files (123) to provide a merged configuration file (124), and deploying the application program (100) into the runtime execution environment (203) based on configuration information from the merged configuration file (124).
