3.e-Service Composition in a Behavior based Framework: e-Service is an operation of outputting and inputting parameters. Under the conditions and effects of both message-based and activity-based, the interactive e-Service can have different combinations. The result of composition can be divided into one-time and reusable. One-time means that the combined results can only be used once and cannot be used for requests from other users. Reusable means that the combined result can be used multiple times and can be used for requests from other users.
