Method and apparatus for session initiation protocol application design, development, execution and integration

The computer program product of clam 8, wherein the descriptor comprises an extensible markup language deployment descriptor.

A data processing system for executing a signaling protocol application, comprising:

• a memory that contains a set of instructions comprising a signaling protocol application, a controller, and application data comprising global application data and global application state data required for execution of the application;
• and
• a processing unit, responsive to execution of the set of instructions, that receives a descriptor that defines a plurality of state transitions that may occur during execution of the application and a request message, wherein the controller parses the request message, and wherein the set of instructions comprise logic for examining the application data to determine if a precondition is met, examine the application data to determine if a postcondition is met, and transition handler logic including instance variables, wherein the transition handler logic is adapted to receive and process the request message.
