Abstract: Web interfaces provide convenient access to e-Science services. Discovery Net allows users to construct a reusable workflow for a particular problem, then 'deploy' that workflow as a service accessible through the Discovery Net web portal. The use of JSR168-compliant portlets allows our services to be easily integrated into existing Virtual Research Environments. In this paper we discuss our experiences in adopting and extending portlet technologies in the second generation of our portal. In addition to providing an overview of our deployment system, we identify missing features of the portlet specification and discuss our solutions. We also highlight technical issues and differences encountered when migrating JSR168 portlets between different Portal implementations.
