Abstract

An application flow control apparatus receives a first message based on a transmission trigger when receiving the transmission trigger indicating a transmission of the first message containing flow definition information for specifying an execution sequence of a plurality of applications performing a cooperative processing; calls an application to be executed according to the flow definition information contained in the first message; and transmits the second message containing the flow definition information and a result of execution by the called application to the transmission addressee executing the next application.

Claims

1. An application flow control apparatus having a part of a plurality of applications performing cooperative processing, comprising:

a queue device for receiving a transmission trigger indicating a transmission of first message containing flow definition information for specifying an execution sequence of the plurality of applications; and

a message process device for receiving the first message based on the transmission trigger, calling an application to be executed according to the flow definition information contained in the first message, and transmitting a second message containing the flow definition information and a result of processing by the called application to a transmission addressee executing the next application.

2. A computer readable storage medium storing a program for a computer having a part of plurality of applications performing a cooperative processing, wherein

the program makes the computer execute the processing of

receiving a first message based on a transmission trigger when a queue device receives the transmission trigger indicating a transmission of the first message containing flow definition information for specifying an execution sequence of the plurality of applications;

calling an application to be executed according to the flow definition information contained in the first message; and

transmitting a second message containing the flow definition information and a result of processing by the called application to a transmission addressee executing the next application.

3. The storage medium according to claim 2, wherein said first message contains state management information for indicating the current position of flow, and said program makes said computer execute a processing of specifying said application to be executed according to said flow definition information and the state management information.

4. The storage medium according to claim 3, wherein said state management information contains information for indicating an already executed application, and said program makes said computer execute a processing of creating state management information in said second message by adding said called application to the already executed application.

5. The storage medium according to claim 2, wherein said flow definition information contains information for indicating a branching condition of flow, and said program makes said computer execute a processing of specifying said application to be executed according to the branching condition and a result of processing by the called application.

6. The storage medium according to claim 2, wherein said first message is stored in the same data base as data renewed by said called application, and said program makes said computer execute the processing of renewing the first message to said second message by using the same transaction as the one in which the called application renews data and transmitting a transmission trigger indicting a transmission of the second message to said transmission addressee.

7. An application flow control method for an apparatus having a part of a plurality of applications performing a cooperative processing, comprising the steps of

receiving a first message based on a transmission trigger when a queue device receives the transmission trigger indicating a transmission of the first message containing flow definition information for specifying an execution sequence of the plurality of applications;

calling an application to be executed according to the flow definition information contained in the first message; and

transmitting a second message containing the flow definition information and a result of processing by the called application to a transmission addressee executing the next application.

8. A carrier signal for carrying a program for a computer having a part of plurality of applications performing a cooperative processing, wherein

the program makes the computer execute the processing of

receiving a first message based on a transmission trigger when a queue unit receives the transmission trigger indicating a transmission of the first message containing flow definition information for specifying an execution sequence of the plurality of applications;

calling an application to be executed according to the flow definition information contained in the first message; and

transmitting a second message containing the flow definition information and a result of processing by the called application to a transmission addressee executing the next application.
