Making applications Grid-aware (or Grid-enabled) requires the knowledge of the API of different Grid middlewares. The complexity of these systems, both in terms of underlying technology and functionality, remains high. Moreover, Grid middlewares like Globus and UNICORE are still undergoing many changes. Grid Application Toolkit (GAT), a high-level API for accessing Grid services, provides application developers with a unified, simple and middleware-independent interface to the Grid. In this paper, we present a newly developed adaptor for GAT to access UNICORE services. We also describe how the data management client DataFinder has been Grid-enabled with GAT to access remote files and submit computational jobs to the Grid. DataFinder provides primarily an easy-to-use tool for scientific data management in distributed environments. Within the project AeroGrid, a BMBF-funded project in the German D-Grid initiative, DataFinder is being used as user interface for performing complex simulations in a UNICORE-based Grid infrastructure.
