- 12. CHEF Implementation Architecture - More Detail Tomcat Servlet Container Jetspeed Portal Turbine Framework Tool Turbine Service Velocity CSS Turbine Service Turbine Service Servlet In addition to Jetspeed, CHEF operates within a Servlet container called Jakarta Tomcat. Whereas portlets operate in one “recatangle” which is a subset of the screen, Servlets control the entire HTTP response or even talk non-HTTP protocols.

Notes de l'éditeur
- An advanced users view of SPARC; lots of information in multiple SPARC pages! The typical SPARC collaboration features down the left hand side, page information, resource list, active user list, and chat Streaming video in the lower left. Lots of data and model views throughout the rest of the screen shot.
- Web-based file-system
- The UserDirectory and GroupDirectory services also use Turbine to find the appropriate UserDirectoryProvider and GroupDirectoryProvider at run-time using the same configuration mechanism as the Service API and Service Components.
