A computer implemented method, apparatus, and computer-usable program product for exchanging data using data transformation are provided. A first data binding component receives data from a function selector. A set of data bindings capable of invocation by the first data binding component is available. The function selector determines a content type associated with the data. The first data binding component receives the data and the content type from the function selector. The first data binding component invokes a data binding corresponding to the content type from the set of data bindings to transform the data into a data object. The data object has an object name. A target application is determined based on the object name, and the data object is then routed to a target application.

Exchanging data using data transformation

For seamlessly abstracting metadata in multiple formats, an abstraction module converts first metadata of an incoming object and additional metadata for the incoming object from an annotation map contained by the first metadata into a common format useable. The additional metadata is not part of an original format of the first metadata. A communication module communicates the converted metadata to an adapter in the common format, the adapter processing the first metadata and the additional metadata independent of the original format of the first metadata.

Seamless multiple format metadata abstraction

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.

Method and system for providing a data exchange service provider interface

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 receive a request from a database driver that is compatible with a software application. The request is in a database language format. Further, the computer is caused to parse the request. In addition, the computer is caused to convert the request into an intermediary data format. The computer is also caused to provide the request in the intermediary data format to a common client interface builder that reformats the request into a format that is compatible with a system resource adapter and invokes the system resource adapter with the reformatted request.

Method and system for providing access to adapters

An apparatus, system, and method are disclosed for assuring delivery of an Enterprise Information System (EIS) event to a client. An adapter apparatus polls at least one EIS for an event. The event is staged to a staging table, consisting of an XA-compliant database, in preparation for delivery to the client. The status of the event is marked and the event is delivered to the client. Events delivered to clients that are unresponsive or otherwise unavailable are held until the clients become responsive and then the events are delivered. Delivery of events is confirmed using a transaction service.

Apparatus, system, and method for facilitating communication between an enterprise information system and a client

An apparatus, system, and method are disclosed for providing seamless multiple format metadata abstraction. A metadata application programming interface (API) is provided to abstract metadata from an incoming business object and provide it to an adapter for processing. The metadata API is configured to operate on multiple metadata formats such as SDO and JavaBean such that the adapter receives the metadata from the metadata API in a common format that is compatible with the adapter. In this manner, the multiple metadata formats may be plugably used with 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.

Apparatus and system for producing atom feeds with J2CA adapters

An apparatus and method for improving event delivery efficiency in a polling adapter system is configured to poll an enterprise information system (EIS) to obtain a list of events occurring in the EIS. Each event may be associated with an object key. These events may then be allocated to multiple delivery lists wherein events associated with the same object key are allocated to the same delivery list. Multiple delivery threads may then be generated, with each delivery thread being associated with a delivery list. Each delivery thread is configured to retrieve, from the EIS, events listed in the delivery list associated with the thread and deliver the events to a client.

Polling adapter providing high performance event delivery

An apparatus, system, and method is disclosed for receiving a hierarchical data structure, analyzing the hierarchical data structure to determine what actions are needed to correctly process the hierarchical data structure in a data repository, generating a hierarchical command structure comprising a series of repository-specific commands needed to interface with the data repository, and executing the repository-specific commands to process the hierarchical data structure with respect to the data repository. In selected embodiments, the hierarchical command structure is represented as a series of nodes including a parent node and at least one child node.

Apparatus, system, and method for processing hierarchical data in disparate data repositories

An apparatus, system, computer program product and method are disclosed for the hierarchical rollback of business objects on a datastore. The hierarchical rollback method utilizes a non-linear process designed to restore data to a previous point in the case of a data modification failure in order to prevent incorrect linking and data corruption. The hierarchical rollback methods are generated by retrieving existing data and creating commands in an order that will prevent orphan data in a datastore.

Apparatus, system, and method for hierarchical rollback of business operations

An apparatus, system, and method for providing command manager support for pluggable data formats. The present invention accepts arbitrary hierarchical input data structures even when the hierarchical input data structure represents hierarchical data in a structure independent of a specific type of data repository. A data mediator receives a hierarchical input data structure and determines whether if it is a snapshot structure or a delta structure. If it is a snapshot update, the command manager creates an in-memory map object structure populated with values from a data repository and compares it with the snapshot. Based on the comparison, it generates a DESPI hierarchical command structure in a format-specific mediation module, and the commands are executed in the data repository. If the hierarchical input data structure is a delta structure, the command manager generates a hierarchical command structure and then translates it to a DESPI-compliant command structure. The commands are then executed in the data repository.

Apparatus, system, and method for command manager support for pluggable data formats

An apparatus, system, and method are disclosed for implementing failover in a polling adapter without support from an application server. A priority list is stored as part of an adapter configuration that specifies the server names that will participate in a group cluster. Adapters associated with the servers, in addition to accessing the event table when active, access a failover table which contains information about which adapter is currently active and when it last polled the event table. When a preconfigured failover interval has elapsed since the last poll of the event table by the active adapter, a next highest priority takes over the processing duties by polling the event table and logging its last poll time in the failover table.

Provided are a method, system, and article of manufacture for generating from application modifications commands to modify the objects in a repository. An input object including an update to at least one of a plurality of objects in a repository object is received. At least one maintain property associated with at least one of the objects is received. The at least one maintain property indicates whether to maintain the at least one object associated with the maintain property in the repository object that is not indicated in the input object. A determination is made of an object in the repository object that are not indicated in the input object. For the determined object, the maintain property associated with the determined object is used to determine whether to maintain the determined object in the repository object.

Generating from application modifications commands to modify the objects in a repository
