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).

Abstract: A method for generating one or more satisfaction records for an expression in a software application, the expression including at least one criterion relating to the application wherein the satisfaction of the criterion can be determined only at application execution time, the method comprising: analysing the application to generate a first set of locations in the application where the at least one criterion is potentially satisfied; executing the application; monitoring the application to generate a second set of locations in the application where the at least one criterion is actually satisfied; for each location in the second set of locations generating a satisfaction record indicating that the application satisfied the at least one criterion at the location; and for each location in the first set not in the second set generating a satisfaction record indicating that the application did not satisfy the at least one criterion at the location.

Abstract: A method for generating an application software library comprising the steps of: a static analyser processing a binary input library to identify one or more locations in the binary input library which satisfy a semantic analysis condition; inserting metadata into the binary input library at the one or more locations which satisfy the semantic analysis condition; and linking the binary input library with a binary aspect library to generate the application software library, wherein the binary aspect library includes an aspect definition using the metadata.
