Developing portal/portlets using Enterprise JavaBeans for Grid users
R Allan (CCLRC Daresbury Lab.)
A web based portal acting as a presentation layer to the Grid allows us to provide a transparent means of access to Grid resources. Our previous experiences in developing Grid portals have shown that there is a need to draw a clear high-level picture of the architecture. This could be defined using the J2EE component-oriented architecture, which enables a clear separation between the presentation, business logic and data layers. Additional benefits come with J2EE 1.4 making it possible to build up advanced service-based Grid portals by exposing stateless session beans as web services. In this paper, lessons learnt from our prototype portal/portlet development using Enterprise JavaBeans (EJB) are reported.
