Portlet container

The portlet container is the runtime environment for portlets using the JSR 168 Portlet Specification, in which portlets are instantiated, used, and finally destroyed. The JSR 168 Portlet API provides standard interfaces for portlets. Portlets based on this JSR 168 Portlet Specification are referred to as standard portlets.

A simple portal framework is provided by the PortletServingServlet servlet. The PortletServingServlet servlet registers itself for each Web application that contains portlets. You can use the PortletServingServlet servlet to directly render a portlet into a full browser page by a URL request and invoke each portlet by its context root and name. See Portlet Uniform Resource Locator (URL) addressability for additional information. If you want to aggregate multiple portlets on the page, you need to use the aggregation tag library. See the article Portlet aggregation using JavaServer Pages for additional information. The PortletServingServlet servlet can be disabled in an extended portlet deployment descriptor called the ibm-portlet-ext.xmi file.

Remote request dispatcher support for portlets

The remote request dispatcher (RRD) support allows the invocation of portlets outside of the current Java virtual machine (JVM) within an Network Deployment single core group environment. The request related data is passed to the remote JVM where the portlet is invoked. The response is transmitted back and processed on the local JVM. Thus it guarantees that URLs contained in the portlet markup are created according to the local portal context.
