  • Publication number: 20080123668
    Abstract: Dynamic inter-operability of nodes in services grids can be provided. In some cases, different version service nodes in a service grid can communicate using an inter-operability service to, for example, convert messages from one format associated with a version of a service node to another format associated with another version of a service node. Also, the message format may be converted from a current (e.g., newer) version of a node to another format which is compatible with an older version of a service node. The inter-operability service can be provided as a web service that is separate from the service nodes in the grid. The inter-operability service is associated with at least one of the service nodes in the grid and is available thereto via, for example, an administrative call by the associated service node.

  • Patent number: 7249178
    Abstract: The present invention is a method and system for non-intrusively dispatching service requests in a service node nested in a service topology. The method can include receiving a service request in the service node and identifying a requested operation and corresponding parameters for the requested operation from the received service request. A port end point address can be obtained for the requested operation and a service list can be located for the requested operation. It can be determined whether the service node is a destination hub. If so, an operation corresponding to THE service request can be invoked. Otherwise, a service node at a different level in the service topology can be selected and the foregoing process can be recursively performed.

  • Patent number: 7246146
    Abstract: A method and apparatus for navigating screens in a legacy host system. In a preferred embodiment, requests for specific legacy host screens are received by a server. The server then navigates to the appropriate screen within the legacy host system and retrieves the host screen. Any intermediate screens navigated by the server in reaching the host screen are not displayed to the user. If variable data need be entered to access the host screen, the server sends the user a submittable form on which to enter the appropriate information, which, once entered and sent to the server, is used by the server to retrieve the host screen. Once the host screen has been retrieved, the server formats it into a web page format using a hypertext language and sends the screen to the user. Other screens within the legacy host system are accessed by user selection of selectable links displayed to the user.

  • Patent number: 7134075
    Abstract: A method, system, and computer program product for efficient processing of Extensible Markup Language (XML) documents in Content Based Routing (“CBR”) networks. Specifically, the method involves converting existing XML documents to a machine-oriented notation (“mXML”) which is significantly more compact than XML, while still conveying the content and semantics of the data and the structure of the document. Documents are converted from XML to mXML upon entering a CBR subnetwork and/or upon receipt by an mXML-capable device. The documents are then processed in mXML format. Devices within the inventive system are provided with an awareness of whether target devices or processes are mXML-capable. Documents being routed to a target which is mXML-capable are passed in mXML format while documents being routed to a target which is not mXML-capable are converted to XML before they are passed.

  • Patent number: 7130964
    Abstract: The present invention provides a method, system, and computer program product for caching objects to improve performance and resource utilization of software applications which interact with a back-end data source, such as a legacy host application and/or legacy host data store or database. Read-only requests for information are satisfied from the cache, avoiding the overhead of a network round-trip and the computing overhead of repeating an interaction with the back-end data source. Refreshes of cached objects and update requests to objects may be queued for delayed processing (for example, at a time when the system is lightly loaded), thereby improving system resource utilization. A sequence of actions that may be required to initiate, and interact with, the refresh and update processes is also preferably stored in the cached objects. This technique is applicant-independent, and may therefore be used for objects having an arbitrary format.

  • Patent number: 6941511
    Abstract: The present invention provides a method, system, and computer program product for applying transformations to extensible documents, enabling reductions in the processing time required to transform arbitrarily-structured documents having particular well-defined elements. Signatures for structured document types are defined, along with one or more transformations to be performed upon documents of that type. The transformations are specified using syntax elements referred to as maps. A map specifies an operation code for the transformation to be performed, and describes the input and output of the associated transformation. A special map processing engine locates an appropriate transformation object to a particular input document at run-time, and applies the transformation operation according to the map definition. This technique is preferably used for a set of predetermined core transformations, with other transformations being processed using stylesheet engines of the prior art.

  • Publication number: 20050172013
    Abstract: Operational rules are transmitted from a first service node that receives a request for service to a second service node that is configured to apply the operational rule to requests for service in response to the request. For example, operational rules can be propagated from a primary node to a secondary node that operates responsive to the primary node, wherein the operational rule defines how the secondary node is to process the request for service from the primary node. Furthermore, the operational rules provided by the primary node can be propagated in a hierarchical fashion throughout the grid to other nodes.

  • Patent number: 6904562
    Abstract: A machine-oriented notation for representation and interchange of extensible documents: a method, system, and computer program product for operating upon (e.g. parsing, and storing documents in) this notation. The notation, referred to herein as “mXML” for “machine-oriented XML”, is designed to be more compact than the Extensible Markup Language (XML), while still conveying the content and semantics of the data and the structure of the document. Documents may be created directly in mXML. In general case, a document represented using mXML notation can be processed more efficiently than when using the existing human-friendly XML notation, requires less storage space, and has a lower transmission cost for data interchange. XML documents can be converted to mXML using techniques of the present invention, and vice versa. Techniques disclosed herein are also applicable to notations other than XML.
