Abstract: Message oriented middleware publish/subscribe technology and wireless push protocol is used to provide wireless messaging services for wireless devices. In the exemplary embodiment, a messaging system brokers messages between publisher applications (i.e. content providers) and wireless client devices (i.e. content subscribers), receiving and distributing messages to subscribers having subscribed to particular content. Messages are pushed to clients via a wireless gateway using a wireless push protocol. Message content subscription is used to filter messages to subscribers with fine granularity to provide a higher quality of service.

Abstract: A technique for serializing both logical and physical meta-model information in a single file is disclosed. In an embodiment, the logical meta-model information is serialized in an Extensible Marking Language (XML) schema compliant format, and the physical meta-model information is inserted into the logical meta-model in suitable locations such that the mappings between the logical and physical meta-models are preserved. In an embodiment, an XML “appInfo” annotation is used to carry physical meta-model information used by multiple applications and suitably placed in a nested configuration with its corresponding logical meta-model information.

Abstract: A debugger allows debugging of applications using a flow paradigm. Breakpoints may be set based on the flow model. Similarly, variables used by the flow model may be queried. Debugging information may be presented in a graphical user interface, in conjunction with a depiction of the application using a flow diagram.

Abstract: A computer readable medium, method, and device for generating eXtensible Markup Language (XML) schema fragments for use in validating an XML message in a particular wire format is disclosed. The method uses as its input a custom XML schema based message model containing logical model extensions or wire format specific rendering options. The output of the method is an XML schema that includes XML schema fragments. The output schema complies with an accepted XML schema standard recognized by a standard schema validator. At run time, the output XML schema, along with the standard schema validator, may be used at a node which does not understand the custom message model to validate incoming XML messages. Depending upon the manner of generating of the XML schema fragments, the resultant validation may be strict or lax.

Abstract: In a development environment for message flows, a user defined flow may be processed into a more efficient optimized flow. However, debugging execution of the optimized flow may be confusing to the user where a correspondence between connections in the optimized flow and connections in the user defined flow are not direct. To mitigate this confusion, a connections mapping table is generated along with the optimized flow. The deploy document received by the runtime may include enough information to recreate the connections mapping table such that during debugging of the optimized flow, the user may follow the user defined flow. The use of a stack at the runtime allows a debugger to maintain awareness of previous pauses in execution caused by the placement of breakpoints on connections in the user defined flow while directing the runtime through execution of the optimized flow.
