The invention provides a method, system and computer program product for caching dynamic portal pages without changing the existing caching proxy infrastructure or the transportation protocol used by providing an advanced caching component. An advanced caching component provides the functionality that additional dynamic page specific cache information is provided as part of the response including the portal page. Each component in the portal that dynamically contributes page fragments to be aggregated to a portal page provides dynamic component specific cache information which includes component specific cache scope and expiration values. The component specific cache scope and cache expiration values are used to calculate dynamic page specific cache information resulting in a common minimum cache scope and a common minimum cache expiration values for a portal page to be aggregated. The dynamic page specific cache information ensures that the minimum cache scope is correctly chosen as contributed from the components and the minimum cache expiration does not exceed any of the component specific cache expiration values.

A method whereby packages of data, and particularly Java objects, are represented in serialized form on a storage medium before they are transmitted or stored. The packages of data are examined for non-application-dependent identifications and are altered whereby the non-application-dependent identifications are replaced by substitutes which require little storage space. In a further embodiment, the application-dependent identifications too are represented by special substitutes. The data package is represented so that it can be stored on storage media and can be restored unchanged at any desired time on any desired system. The restoration is performed by applying the algorithm in a similar way but in reverse, once again in a black box.

The present invention provides a Dynamic Portal Assembly for Portals which provides the function to manipulate whole topology tree of a Portal at runtime. Topology Fragments, that are partial topology trees, are computed by software components called Adapters and are merged with existing trees at run time. The Adapters themselves can base the computation on the states of External Systems, e.g. Workflow Systems. The introduction of an Independent Adapter Interface allows for easy deployment of new Adapters into the Portal. In a preferred embodiment of the present invention the Dynamic Portal Assembly is adapted to integrate Workflow into Portal without giving awareness to the Portal user.

The present invention discloses a method allowing dynamically integrating remote portlets into each Portal by providing local portlets as remote portlet Web-Services by providing, to each Portal-Server, a publishing functionality allowing electronic creation of a service description for each single local portlet and publishing it into a Central-Registry and a find/binding functionality to find remote portlet Web-Services via the Central-Registry and bind them using the service description for accessing the remote portlet. Preferably, each Portal-Server includes a Portlet-Registry component as well as a Portlet-Proxy. The Portlet-Registry provides service description to the Portlet-Proxy that establishes a SOAP-communication with a remote Portal-Server providing the remote portlet Web-Service to be selected. The main advantage of the present invention is that local portlets become available for all Portal-Server without requiring local installation of the portlet code itself. Furthermore, new remote portlets can be included into a portal by finding them in a registry and binding them.

Techniques are disclosed for incrementally rendering content in a content framework (such as a portal page provided by a portal system). Upon receiving a request for a portal page, a portal server immediately returns a response including the results from portlets which have acquired their content. If some portlets have not yet finished, subsequent content is delivered at a later time through use of one of several alternative programmatically-generated mechanisms. Capabilities of existing browsers are leveraged for several embodiments, including use of refresh headers, multipart MIME (“Multi-purpose Internet Mail Extensions”) types, and portal pages structured using frames.

The present invention describes a method for downloading application components, so-called on-card application components, from a server via a client to a chipcard, wherein the server and the client communicate with each other via a distributed system, in particular an Intranet or the Internet. The advantages of the present invention lie in the fact that downloading of the application components is divided into two stages: The first stage occurs on the server only, and ensures that not every command to download the application component is sent individually over the network. This is effected by means of a broadband-optimized protocol which bundles the individual commands to download the application component into a command sequence and sends it as a complete data packet over the network. This reduces the time required for downloading application components over the network. Each command within the command sequence is assigned a digital signature and, where appropriate, encrypted. This ensures that only authenticated commands are accepted by the chipcard. In this way this invention meets security requirements for the transfer of data via distributed systems, in particular over the Internet. The second stage occurs between the client and the chipcard, and ensures that the data packets are unpacked and sent individually to the chipcard. All security-relevant keys and certificates are stored on the secure server. Communication between the client and the server runs preferentially via SSL (Secure Sockets Layer) as the transfer protocol. Misuse of the inventive system/method is thereby rendered much more difficult.
摘要:
A method for differential rendering a portal page that includes a plurality of page elements (10, 12, 14) and refreshing the portal page. The method includes providing a complete portal page (20, 22). A request for the portal page is then sent and/or received (28). The request can represent user events. In a next step, page elements (10, 12, 14) of the portal page to be updated are identified (30, 31) on the basis of the user events. A page delta is then calculated (32), wherein each page element (10, 12, 14) is associated with a refresh policy depending on the semantics of the respective page element (10, 12, 14). The page delta can include the markup elements of the page elements to be updated. Next the page delta is transferred (34) to the existing portal page and merged (40) with the existing portal page.

The present invention provides a system and method for dynamically integrating remote Portal fragments into a local Portal while maintaining the look and feel of the local Portal by receiving Meta-information of the remote Portal fragment, integrating said Meta-information into the existing navigation tree of the local Portal resulting in an new navigation tree, traversing the new navigation tree for rendering the integrated Portal page, identifying references in the new navigation tree for remote Portal fragments, establishing Communication with the remote Portal, and receiving and including remote Portal fragments into the local Portal page. The present invention secures a seamless integration of Portal fragments into the local Portal while maintaining the local Portal's look and feel.
摘要:
A system providing a bi-directional feedback loop that assists project management to make timely decisions and alterations based on personal calendar data retrieved from team members' calendars. The system provides a project manager user with perceptible alerts in a project manager user interface in response to detecting a conflict between proposed or actual personal calendar events of a team member user and deliverables assigned to that team member user. The project manager user interface enables the project manager to take an action in the event such a conflict is detected. Project manager actions in this regard may include permitting a conflicting personal calendar event, forbidding the conflicting personal calendar event, delegating the conflicting deliverable to another team member, adjusting the deliverable requirements, and/or escalating the conflict to a higher level of management.
