Component adaptation becomes a critical problem in component-based software engineering (CBSE). This problem appears during assembling and reusing of components into new system. The interoperability among components needs to use adaptation technique to solve this problem. Usually, there are mismatches between interfaces of reusable components. This research will focus on detecting fully semantic component interface mismatch by proposing a solution including return value match next to other match such as operation name, method of operation and parameter type match. This research just explains return value mismatch that are not considered in other solutions. The proposed solution also concerns about system performance that is neglected in previous solutions by proposing a ‘Detector’ tool that is responsible to assign and delete unwanted functions from reusable component before integration.
