K-Wf Grid application portal provides convenient web based user interface for the tools and applications being developed in the context of the K-Wf Grid project.
Users with valid portal account can access various portal sections focused on K-Wf Grid’s applications and associated knowledge, application monitoring and grid services.
The portal is built on the Gridsphere portal framework. The framework is an implementation of a portlet paradigm defined in JSR-168 Portlet API Specification – portlets are self-contained components generating just part of the portal page, independent from each other that are pluggable into the portal. The Gridsphere framework provides the environment for running the portlets, portlet state management, session management and various other tasks. The gist of the K-Wf Grid portal development lies in the development of the portlets providing user interfaces to various K-Wf Grid software components.
The following table shows the portal structure:
