An apparatus for and method of predefining a series of messages between a client application and a server application which needed to be transferred and honored in sequence to perform a compound service request. The sequence of messages is predefined through the use of an Action Control List, whereby the event handler defines the messages to the administrative object.

Method and apparatus for sequenced message processing between an event handler and an administrative object

An apparatus for and method of utilizing an existing predefined messaging protocol to convey additional data in application-to-application communication. Instead of utilizing a plurality of the existing predefined messages or defining a new unique message type to convey the needed data, a single preexisting message type is used to define location and format of the data objects to be communicated. The receiving application unpacks these definitions from the single message received and accesses the defined data objects as required.

Method and apparatus for combining extended markup language and key/value pairs into the format of an interprocess message payload

An apparatus for and method of improving the efficiency of service request/response activity requiring security functions. A security facility, such as Security Support Provider Interface is embedded in a communication class library which controls the communication between client and server applications. A context token is associated with the service request which specifies the security functions to be provided in honoring that particular request without any particular attention by either client or server application, as the security functions are exclusively concerned with the communication process rather than the service request/response activity.
