  • Patent number: 8099501
    Abstract: An apparatus for and method of processing service requests having a number of formats within a single generic gateway. The service requests are received by the server and routed to the appropriate one of a number of adapters. Each of the adapters convert service requests to a standardized format for input to the single generic gateway. The output of the single generic gateway is coupled through a corresponding one of a number of connectors to the end service provider for honoring.

  • Patent number: 8041836
    Abstract: A system and method which automatically converts COBOL data definitions into view files which allows a user from an Internet terminal to access an On-Line Transaction Processing (OLTP) enterprise server. This conversion permits the Internet user to perform COBOL transactions using the enterprise legacy system.

  • Patent number: 7111077
    Abstract: An apparatus for and method of processing service requests provided by a user at a standard Internet work station. The service requests are received by the server and routed to a gateway. The gateway has the capability to convert the service request to a format acceptable by an enterprise server without the need of a view buffer. Thus, the conversion does not require a priori notification concerning the data formats employed. The output of the gateway is coupled through a corresponding one of a number of connectors to the end service provider for honoring. The response is transferred from the service provider to the appropriate connector to be formatted for the requesting gateway. The response is converted by the original adapter to an HTML or XML message for transfer back to the requester via the Internet.

  • Patent number: 6993585
    Abstract: An apparatus for and method of processing service requests presented as XML messages an-d having a number of formats within a single generic gateway. The service requests are received by the server and routed to the appropriate one of a number of adapters. Each of the adapters convert service requests to a standardized format for input to the single generic gateway. The output of the single generic gateway is coupled through a corresponding one of a number of connectors to the end service provider for honoring. The response is transferred from the service provider to the appropriate connector to be formatted for the common generic gateway. The response is converted by the original adapter to an XML message for transfer back to the requester via the Internet.

  • Patent number: 6721776
    Abstract: A generic server and gateway that run within a Distributed Component Object Model (DCOM) environment capable of receiving requests from one or more different types of DCOM clients for service by an On-Line Transaction Processing (OLTP) style application running on an enterprise server. The services on the OLTP system are designed to accomplish a specific task, for example, update a user's bank account balance following a debit or credit. In a preferred embodiment, the OLTP system is X/Open compliant. The DCOM Client can be any type of client, including a Visual Basic client, C++ client, or a Web Browser with Active Server Pages (ASP). The generic server and generic gateway are vendor supplied components which tend to insulate the client developer from the details of the communication protocol with the OLTP system.

  • Patent number: 6715080
    Abstract: A system and method which allows the interchange of Cookie information and standard Common Gateway Interface (CGI) variables between a user system and an On-Line Transaction Processing (OLTP) enterprise server. The present invention also discloses a specialized form of a transaction gateway, known as a security gateway, which runs on a Windows NT or UnixWare Web Server machine, and is built as a client application to interoperate with an enterprise-based OLTP security service. Finally, the present invention discloses an enterprise-based OLTP security service, which is used in conjunction with the security gateway described above, which processes user generated authentication requests, and if successful, calls an end service requested by a user.

  • Patent number: 6643679
    Abstract: A preprocessing DLL which may be appended to a service request for transfer to a gateway that runs within a Distributed Component Object Model (DCOM) environment, and is capable of receiving requests from one or more different types of DCOM clients for service by an On-Line Transaction Processing (OLTP) style application running on an enterprise server. The services on the OLTP system are designed to accomplish a specific task, for example, update a user's bank account balance following a debit or credit. In a preferred embodiment, the OLTP system is X/Open compliant. The DCOM Client can be any type of client, including a Visual Basic client, C++ client, or a Web Browser with Active Server Pages (ASP). The preprocessing DLL permits the efficient web server side preprocessing of data associated with the service request before the service request is transferred to and honored by the enterprise OLTP system.
