Pluggable Engines Pluggable engines are custom Java classes written against a public API. Plugged into the server, these engines enhance the server with their functionality, as well as leverage the server's other features, such as
notification, and caching.
OracleAS Reports Services provides an out-of-the-box pluggable engine called the URL engine. The URL engine enables you to distribute content from any publicly available URL to such destinations as
OracleAS Portal, and WebDAV.
