What methods are available for building custom portlets?
Custom portlets can be generated from Portal Application Components (forms, reports, charts, and dynamic pages), or built with the APIs contained in the Portal Development Kit (PDK). Application components can also call the PDK’s PL/SQL APIs. For an introduction to using Portal Applications as portlet providers, please see the white paper “Enhancing Oracle9iAS Portal with Data-Driven Portlets”. For more information on building portlet providers with the PDK, please visit http://technet.oracle.com/products/iportal/listing.htm#portlet_develop.
