A method in a computer system is disclosed for discovering host-based legacy screen assets. The system has a client, a server and a host, including a repository. The method comprises the steps of creating an application object comprising a collection of the legacy screen assets; and, creating a recognition file for storing constituent elements of the legacy screen assets. After this, a first stream of data representative of the legacy screen asset is received from the host in response to a request by the client for data fields. Next, the first data stream is parsed into constituent elements and stored in the recognition file and then the constituent elements are associated with the screen assets. The constituent elements of the first data stream are appended to the recognition file for the screen assets; and, then they are associated with data names that are stored in the repository, thereby creating a specification for each of said legacy screen assets.

System and method for discovering host-based application assets for the development of business-centric software components

A method in a computer system, having a client, a server and a host, is disclosed which provides access to host-based legacy screen applications. The method includes the steps of receiving a stream of data representative of the legacy screen application from the host in response to a request by the client for data fields. Next, the data stream is parsed into its constituent elements. The constituent elements are then matched with a recognition file for the screen application. The results of the preceding step are used for retrieving a type library, which stores field information for the screen application. After this, the constituent elements are associated with data names that are stored in the type library. Finally, field objects are created based on the information retrieved from the type library and stored in the server, thereby providing access to them by the client.

System and computer-implemented method for providing access to host-based screen applications using business-centric software components

A system and method in a computer system having coupled thereto a repository for storing data, which method is implemented by the computer system. The method encodes display, entry fields and static text of a screen application (screen data) into Host Reply Definition (HRD), Request (REQ) and recognition files, which are then stored in the repository. A graphical user interface program is used for building and transforming the HRD, REQ and files stored in the repository into components. Next, the HRD, REQ and recognition files are extracted from the repository and associated with the screen application. The attributes of these files are written into a type library, thereby forming the software components. After this, the recognition file is stored in a directory structure independent of the repository. Finally, the components are registered in a registry for recognition by other applications and components.
