A system, method and program product for inserting targeted content into a portlet content stream is provided. Specifically, the present invention provides a portal program that includes a container-managed portlet filter for inserting targeted web content into a portlet content stream based on a desired display mode of the portal user. Under the present invention, web content is obtained by a portlet from a content provider. Once obtained, the portlet outputs the web content as a portlet content stream to the portlet filter. The portlet filter then inserts the targeted content based on the desired display mode of the user. The combined targeted content and portlet content stream is then outputted to an aggregator where it is organized for display as a portal page.

Inserting targeted content into a portlet content stream

A portlet state maintenance system can include a portal page setup component configured to generate a logical form in a single portal page from a multiplicity of forms defined within portlet markup aggregated into the single portal page. A portal state save component further can be configured to save state values for selected portlets defined within the logical form. Finally, a portal state restore component can be configured to restore the saved state values in refreshed portlet markup for the selected portlets. Notably, a refresh timing component further can be configured to embed submit auto-initiation logic in the single portal page responsive to identifying a dynamic refresh requirement associated with the portlet markup in the single portal page. Finally, a portlet markup cache can be coupled to the portal state restore component.

Maintaining screen and form state in portlets

An event to initialize a portlet palette within a user interface having an open portal to which the portlet palette is associated can be detected. The portlet palette can be a user interface control that includes a portlet set of at least one portlet. The portlet palette can be configured so that a selection of a portlet from the portlet set causes the portlet to be added to the open portal. A set of portlets can be automatically determined from a set of stored portlets that are relevant to the open portal based upon previously defined programmatic rules and contextual information associated with the open portlet. The portlet palette can be dynamically populated with the determined set of portlets. The populated portlet palette can be presented within the user interface.

Dynamically adaptive portlet palette having user/context customized and auto-populated content

The present invention describes an adaptive control system being preferably part of the portal, which provides a sophisticated method for a partial sequential and parallel invocation of portlets depending on the available resources and system utilization. Based on defined time mark for rendering content (maximum invocation time for displaying a portal page or a portal-wide portlets rending time mark), a number of available threads, and estimated invocation time for each portlet the inventive method determines and invokes a first group of portlets () providing the maximum number of portlets to be invoked sequentially without exceeding defined time mark for rending content, and then all remaining portlets () are to be invoked parallel to that first group of portlets. The invention guarantees reasonable response times and high scalability and performance. ().

Adaptive control system and method for optimized invocation of portlets

Techniques are disclosed for improving navigation through content in a user interface that has been rendered in a content aggregation framework (such as in a portal page provided by a portal system). The navigation order for the aggregated content is set dynamically, using programmatic operations, based on input supplied in a markup language document. The navigation order may therefore be efficiently controlled, even though the content which is aggregated may originate from multiple independent sources.
