Integration of Existing Grid Tools in Sakai VRE

Abstract

The integration of existing Grid tools into the Sakai VRE (Virtual Research Environment) will be discussed in this paper.In particular we describe the integration of the business logic and JSR 168 compliant portlets through presentationoriented Web Services, via WSRP (Web Services for Remote Portlets).A set of JSR 168 compliant portlets were developed for the UK NGS (National Grid Service) Portal and have been published using WSRP4J and consumed within Sakai successfully, which proves re-use of portlets as web components is a practical option.With the help of the WSRP consumer tool, the Sakai VRE has been successfully extended to support the JSR 168 specification.
