Portlet container
- Portlets
Portlets are reusable web modules that provide access to Web-based content, applications, and other resources. Portlets can run on the application server because it has an embedded JSR 286 Portlet container. The JSR 286 API provides backwards compatibility. We can assemble portlets into a larger portal page, with multiple instances of the same portlet displaying different data for each user.
- Portlet filters
Since the release of JSR 286: Portlet Specification 2.0, it is possible to intercept and manipulate the request and response before they are delivered to a portlet in a given phase. Using Portlet filters you can block the rendering of a portlet if a specific condition occurs. Also, you can use portlet filters to decorate a request and a response within a wrapper to modify the behavior of the portlet.
- Portlet container
The portlet container is the runtime environment for portlets using the JSR 286 Portlet specification, in which portlets are instantiated, used, and finally destroyed. The JSR 286 Portlet API provides standard interfaces for portlets and backwards compatibility for JSR 168 portlets. Portlets that are based on this JSR 286 Portlet Specification are referred to as standard portlets.
