Abstract: A method provides real world contexts to computer applications for outputting data describing one or more real world contexts. Components are identified in a computer application which implement instances of real world contexts and application components are updated so that a real world context instance is active during the execution by the application of a function for the real world context instance. Each real world context instance may have an instance identifier and is referenced by type of real world context.

Abstract: A JMS implementation integrates into an application server based on the JCA Architecture. A JMS Connection is integrated based on one implementation of a JCA which sets transactional context for the JMS Connection to “no transaction”, and the JMS Session is integrated based on a second implementation of the JCA which ignores any security credentials provided. The application is unaware that it is dealing with a JCA implementation and not directly with the JMS implementation and the JMS implementation is unaware that it is being called via the JCA implementation and not directly from the application.

Abstract: 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.

Abstract: A JMS implementation integrates into an application server based on the JCA Architecture. A JMS Connection is integrated based on one implementation of a JCA which sets transactional context for the JMS Connection to “no transaction”, and the JMS Session is integrated based on a second implementation of the JCA which ignores any security credentials provided. The application is unaware that it is dealing with a JCA implementation and not directly with the JMS implementation and the JMS implementation is unaware that it is being called via the JCA implementation and not directly from the application.

Abstract: Thus the present invention provides a method which enables a JMS implementation to be integrated into an application server based on the JCA Architecture. In this method the JMS Connection is integrated based on one implementation of the JCA which sets transactional context for the JMS Connection to no transaction, and the JMS Session is integrated based on a second implementation of the JCA which sets the security property to no security. In the method the application is unaware that is it dealing with a JCA implementation and not directly with the JMS implementation and the JMS implementation is unaware that it is being called via the JCA and not directly from the application. The method thus provides an architecture for integration of a JMS into an application server which takes advantage of the JCA such as provision of security properties and transactional context to the JMS in a standard way, and JMS connection pooling and sharing.

Abstract: Compensation of workflow applications represented by a graph is achieved by including graphical representations of paired primary and compensation tasks and of completion steps indicating success or failure of a process. Execution of a completion step indicating failure of the process causes one or more compensation tasks to run and execution of a completion step indicating success causes commitment of the results of previously executed primary tasks. By associating both a successful and an unsuccessful completion step with a process end point, a compensation group is defined. By associating only an unsuccessful completion step with an inner process within a compensation group, compensation tasks within the inner process whose primary tasks have executed are run if the unsuccessful completion step is reached. Otherwise compensation is deferred pending the outcome of the completion steps of the compensation group.
