If organizations require additional portlets they can build and deploy them along with Oracle's pre-built portlets, as follows:
| Build the portlets in a familiar language, such as Java, PL/SQL, or XML. |
| Define provider procedures according to published API specifications, and register the procedures with Oracle Portal. |
| Retrieve portlet content from Web providers, using XML to send or receive structured data through the HTTP protocol. |
| Retrieve portlet content from database providers using SQL*Net to execute Java or PL/SQL stored procedures. |
Developers can speed development and testing using the Portal Development Kit (PDK) and the Java PDK.
