Abstract
Grids have become a critical asset in large-scale scientific and engineering research. Accessing to distributed data is typically as important as access to distributed computational resources. In this pa- per, we present the design of Java CoG Kit compo- nents and APIs that make handling of data accessed through Grids easier for the novice Grid user and programmer. We introduce the design and archi- tecture of a component for file transfers that sep- arates issues related to requesting, performing and visualizing the actual file transfer. The design of our component is based on object and component based methodologies. Hence, it is assembled from a collection of reusable components promoting cus- tomization and reuse. We integrated the drag-and- drop paradigm. Protocol-independent interfaces al- low easy adaptation to a variety of data sources. Hence, we not only have developed a GUI but so- phisticated middleware to develop advanced Grid file transfer services. These components are dis- tributed with the Java CoG Kit.
