A system for use in a distributed environment comprising a first data processing system having a first entity (e.g. an object) and a second data processing system having a second entity. The first entity sends a request for an operation associated with the second entity. The request comprises an operation identifier in a first format (e.g. a first national language) and the operation comprises an operation identifier in a second format (e.g. a second national language). The environment also comprises a data structure comprising an association between the operation identifier in the first format and the operation identifier in the second format. The system comprises an intercept component for intercepting the request, a search component for searching the data structure for the operation identifier in the first format and a map component for mapping the operation identifier in the first format to the operation identifier in the second format.
