A computer program product comprises a computer useable medium. The computer useable medium has a computer readable program such that when the computer readable medium is executed on a computer, the computer is caused to provide a data interface between an adapter component and one or more application interface components for a runtime application. Further, the computer is caused to establish a cursor that iterates over a plurality of data objects within a data set of the runtime application. In addition, the computer is caused to establish an accessor that provides access to a data element of the data object. The computer is also caused to provide the cursor and the accessor to the adapter component so that the adapter component accesses data through the one or more application interface components of the runtime application.

An apparatus and system are disclosed for receiving a data set from a data-exchange server, generating methods for accessing and performing operations on data in the data set from metadata defining the data set, using the access methods to generate a method for transforming the bidirectional format of the text data between the format of the server and a format defined in the metadata of the data set, and automatically employing the transformation method to transform the bidirectional format of text data in the data set, prior to performing an operation on the data, to the format appropriate to the particular operation.

Presented herein is a method and computer program product for generating, in an Integrated Development Environment (IDE), a software application that is designed to exploit services of multiple Enterprise Information Systems (EISs). In one embodiment, the method associates each of multiple Resource and Tooling Adapters (RTAs) with a selected one of multiple Enterprise Information Services (EISs). A software application, which uses multiple EISs and is developed through development facilities of an Integrated Development Environment (IDE), is identified. Source code that is used to access the services of the multiple EISs is generated by plugging multiple corresponding RTAs into the IDE. Using plugged-in multiple corresponding RTAs in the IDE, data is provided, to the IDE, that describes services available from the multiple EISs to the software application.

Automated interface generation for computer programs operating in different environments is provided. An automated interface generation system, method, computer program product and article of manufacture is provided comprising an import utility and a runtime environment. The import utility imports a COBOL IMS transaction source file, parses the specified input and output message records, and generates an application programming interface. The application programming interface operates with the runtime environment to take the data values from the language of a different environment and translate them to a formatted IMS input message. This format is derived from the definition of the input message record in the COBOL IMS transaction source file. After the IMS transaction has executed, the resulting IMS output message is translated back to the data values of the language of the different environment, said values including the results of the transaction. The translation step handles data conversion between different code pages, machine architectures, and program semantics, and handles the dynamic nature of IMS messages.

A computer system and method including commands to permit interaction between a client and a component in a backend system. The command has an input object, for transformation by the backend system, and defines one or more output objects, representing the input object after transformation by the backend system. The command includes a connection specification, for identification of the backend system with which the client is to interact, and an interaction specification, for identification of the component in the backend system with which the client is to interact. The command also includes a communication object, for carrying out a connection between the client and the component of the backend system. The input object is supplied to the component of the backend system in accordance with the interaction specification and the connection specification. The command is driven by an execute method and the command signals a successfully or an unsuccessful event depending on exceptions being encountered by the component of the backend system in processing the input object. Navigators are built for constructing an interaction flow. Navigators contain chained commands and other navigators.

A computer program product comprises a computer useable medium. The computer useable medium has a computer readable program such that when the computer readable medium is executed on a computer, the computer is caused to configure an adapter such that the adapter is specific to a data source, provides a communication link to the data source, converts a format of the data source to a format native to a middleware system, and converts a format of metadata of the data source to a standard metadata format. Further, the computer is caused to configure an application interface component to convert an invocation of a function in the middleware system to an invocation of a function provided by an Enterprise Information System through the adapter, convert the data format of the middleware system to a format native to the Enterprise Information System accessed through the adapter, and maintain metadata describing a message format and a function provided by the adapter.

A servlet for enabling communications between a client having an Atom feed reader and an Enterprise Information System (EIS). The servlet enables communications between the client and the EIS by acting as a proxy for an J2CA resource adapter deployed on an application server. The servlet receives HTTP requests from the Atom feed reader and translates those requests into appropriate adapter function calls based on the specified HTTP function and the provided key information. The servlet then invokes the appropriate functions and receives the response from the adapter. If a single object is returned by the adapter, the servlet translates the object into Atom-compliant XML and transmits it to the Atom feed reader as the response. If multiple objects are returned, the servlet generates a list of URLs which uniquely specify and identify each object returned by the adapter and provides this list to the Atom feed reader.

The invention relates to Web Services Invocation Framework (WSIF) operations. “interactionSpec” and “connectionSpec” are Java 2 Enterprise Edition Java Connector Architecture interfaces. Their properties are exposed as data in WSIF operations. Thus WSIF support for the Java 2 Enterprise Edition Java Connector Architecture is made functionally more complete.

A method and apparatus are disclosed for discovering and selecting faults where more than one programming model is involved. The present invention enables selection of faults and the mappings necessary to handle exceptions across multiple code environments.
摘要:
An apparatus, system, and method are disclosed for accessing enterprise information system (EIS) resources in a service component architecture (SCA) for an integration server by selectively binding a service import to a low-level EIS resource adapter (RA) resource of an EIS service provider in response to a declarative binding definition, selectively binding a service import to an EIS service of the EIS service provider in response to a declarative binding definition, and selectively binding a service import to one or more EIS resources through an EIS service mapping configured to transform a service request from the service component client to satisfy an interface pattern of the EIS service provider. By allowing access to resources at different levels and allowing mappings of resources, the requirements of service clients can be met.
