6 OGCE Project The Open Grid Computing Environments (OGCE) project consists of the following core constituent areas for developing powerful, Web-based Science Gateways to Grid resources such as the TeraGrid. Development of interoperable, standards-based Web components (portlets) for Grid computing. Grid client programming libraries and tools development. Development of Web Services to support Grid portals’ information, metadata, and job execution and management requirements.

7 Highlights and Major Contributions OGCE Grid Portal Grid Programming Interfaces and Abstraction Layers: Java CoG Kit, Grid Tag Libraries and Beans (GTLAB) Portlet Development: Portlet bridge, inner-portlet communication …

8 Java CoG Kit End users will be able to access the Grid through standalone applications, a desktop, or a portal. Command line tools allow users to define workflow scripts easily. Programming is achieved through services, abstractions, APIs, and workflows.

9 Grid Tag Libraries and Beans The goal of GTLAB is to make it possible to develop Grid Web applications entirely through reusable tag libraries with no additional coding. GTLAB extends Java Server Faces and encapsulates the [Java_COG_Kit | Java COG Kit's Abstraction Layer]. Can convert the GTLAB applications into portlets
