A virtual runtime module that omits an internal functional implementation of an associated executable module and that includes a runtime-resolvable public interface of the associated executable module is obtained using a processor within a module-based system. The virtual runtime module within the module-based system is resolved, using the runtime-resolvable public interface of the virtual runtime module, to satisfy dependencies associated with the executable module within the module-based system. At least a portion of the internal functional implementation of the associated executable module within the module-based system is installed during runtime using the resolved virtual runtime module.

A method of ordering multiple resources in a transaction includes receiving a transaction for a plurality of resources and determining, for each resource, the work embodied by the transaction. The work includes at least one identified parameter relating to an operation for the resource. The method further may include specifying an order of the resources according to the determination of the work, committing the transaction, and invoking the resources in the selected order. Specifying the order of the resources may include specifying the resource to be invoked last. Alternatively, or additionally, specifying the order of the resources also may include specifying that each resource carrying out read-only work be invoked first.

A method and system are provided for concurrent message processing. The system includes: an input queue capable of receiving multiple messages in a given order; an intermediary for processing the messages; and an output queue for releasing the messages from the intermediary. Means are provided for retrieving a message from an input queue for processing at the intermediary and starting a transaction under which the message is to be processed. The intermediate logic processes the transactions in parallel and a transaction management means ensures that the messages are released to the output queue in the order of the messages in the input queue.

A method, apparatus, and a computer program product are disclosed for selectively activating a trace function in a computer program in response to a call of a predetermined trigger code element so that trace data is produced only for those subroutines that call the trigger code element or are called by the trigger code element. The computer program product provides one or more trace code elements for one or more selected subroutines of the computer program stored on internal memory of a digital computer. The trace code elements provide trace data for said selected subroutines. The computer program product also selects a subroutine as a trigger code element, processes the computer program, monitors the call stack for the trigger code element, and enables the trace code elements for each selected subroutine simultaneously present in the call stack if the trigger code element is identified in the call stack.

Transforming an original message from an application executed by a physical computing device to create a message readable by a plurality of heterogeneous recipients includes: creating with the physical computing device a first sub-message having data from the original message that is readable by each of the heterogeneous recipients; creating with the physical computing device a second sub-message having data from the original message that is not readable by each of the heterogeneous recipients; and generating with the physical computing device a composite message including both the first sub-message and the second sub-message.

Creating a message readable by a plurality of heterogeneous recipients

Message type validation occurs at a message producer before a message is sent to a message destination. A message producer system includes an administrator component, which stores message type parameters associated with a message destination. A message is created for the message destination and a validation component at the message producer system checks the created message for conformity with the stored message type parameters for the message destination. An error is reported if the message type does not conform to the stored message type parameters associated with the message destination. The validation component checks the created message for conformity after a publish call by the message producer system and before a send call and, therefore, prevents an invalid or non-conforming message from being sent.

Input to a transformation engine is produced, responsive to a client computer providing a data access service (DAS) computer with XML data for transformation, by creating a graph shell and XML store for the XML data, determining if the graph has a store; and, if so, requesting an empty TrAX result; requesting to fill the empty TrAX result using TrAX source, and requesting a store parser for events related to the XML store; while avoiding wrapping by the TrAX DAS of a graph shell with TrAX source, requesting by a TrAX source of a graph for one or more nodes, requesting by a graph from a store for one or more nodes, parsing of a buffer by a store, returning events from a store to a graph, building of a graph by the same graph, returning nodes from a graph to a TrAX source; and building events by a TrAX source.

Provided are a method, system, and program for generating asynchronous interfaces and methods from synchronous interfaces and methods receiving a synchronous interface to a target component having a synchronous method used by a client component to synchronously invoke the target component. An asynchronous interface is generated for the synchronous interface of the target component. An asynchronous method is generated for the generated asynchronous interface having arguments to invoke the target component, wherein the client calls the generated asynchronous method to cause an asynchronous execution of the synchronous method.

A data processing method, apparatus, computer program product, and service for assuring timely execution of compensation for non-transactional work which is carried out in a transaction under which a data item is processed. A lock is taken before the data item is processed and, in the event the transaction fails, the same lock is also obtained before the data item is re-processed. As a result, re-processing of the data item is held until the lock obtained by the failed transaction is released and this is only done once compensation of non-transactional work is complete. Thus, compensation completes before the message is re-processed.

Compensation of data item processing

A workflow application is represented by a graph comprising a plurality of components, some of which may be processes. At least two of the processes are interpreted according to different respective sets of rules. The sets of rules are implemented in either a plurality of respective navigation engines or in a single engine implementing multiple sets of rules.

Disclosed is apparatus for processing business data processing activities, the apparatus comprising: an activity instance; and a descriptor for the activity instance associated uniquely with the activity instance; wherein the descriptor includes parameters for determining lifecycle behaviors of said activity instance. The descriptor may be programmable to modify the lifecycle behaviors according to a use made of said activity instance. The use of the activity instance may be responsive to a request by a client. It may also be responsive to a request by an activity instance. The descriptor may be programmable to modify the lifecycle behaviors according to a position in a system hierarchy of the activity instance.

Data processing activity lifecycle control

Disclosed is data processing apparatus comprising: means for receiving inputs indicative of results from one or more participants of said one or more sets of data processing tasks; means for mapping each of said inputs to a corresponding mapped value by accessing a mapping table; outcome processor means for accepting the mapped values as inputs and determining an outcome for said one or more sets of data processing tasks; and means, responsive to said means for determining, for transmitting an indicator of said outcome to said one or more participants; wherein the inputs and mapped values of the mapping table are programmably changeable to thus provide a high degree of flexibility with respect to said inputs.
